Maine Water Restrictions 2026

Water restrictions across Maine right now

Maine enters 2026 in a position that many western states can only envy: no active water restrictions anywhere across the state. From the sandy beaches of York County to the remote timberlands of Aroostook County, municipal water systems are operating without mandatory conservation orders, voluntary appeals, or emergency curtailments. The two largest cities in the state — Portland and Bangor — both report unrestricted water use as of the most current monitoring period, a reflection of the abundant precipitation that characterized the preceding months across most of New England.

This is not an anomaly for Maine. The state's combination of relatively low population density, extensive freshwater resources, and a climate that delivers consistent rainfall across the year means that outright water restrictions are uncommon compared to states in the arid Southwest or drought-prone Southeast. Maine receives an average of 44 to 47 inches of precipitation annually, distributed fairly evenly across the calendar, which helps utilities maintain reservoir levels and aquifer recharge without requiring customers to significantly alter their water use habits.

The absence of restrictions, however, does not mean that Maine water managers are complacent. The Maine Drinking Water Program, which sits within the Maine Center for Disease Control and Prevention's Division of Environmental Health, continues to monitor supplies at public water systems throughout the state on a regular basis. Utilities in communities like Augusta, Lewiston, and Waterville submit operational reports that track daily production, storage capacity, and demand trends — data that would trigger early warnings if conditions began to deteriorate.

Portland Water District, one of the largest and most sophisticated utilities in northern New England, routinely communicates with its customers about long-term water stewardship even when no emergency exists. The district draws primarily from Sebago Lake, one of the cleanest large lakes in the eastern United States, and it monitors that system year-round. Even in normal years, the district encourages voluntary efficiency as a baseline practice rather than waiting for drought declarations to motivate behavioral change.

Bangor Water District, serving the greater Penobscot River region, similarly operates without current restrictions. The district's storage reservoirs in the hills west of the city are at healthy levels, and treated water demand has remained within expected seasonal ranges. No boil-water advisories, no pressure reduction orders, and no irrigation limitations are in effect.

For Maine residents planning landscaping projects, filling backyard pools, or running irrigation systems this season, 2026 presents no regulatory barriers at the state or local level. That said, water managers uniformly encourage residents to think about efficiency not as a crisis response but as a permanent habit — a message reinforced by the Maine Department of Environmental Protection and numerous local watershed councils throughout the state.

Fines and enforcement in Maine

Enforcement of water restrictions in Maine is handled at the utility or municipal level rather than through a uniform statewide penalty code. When restrictions are active, utilities derive their enforcement authority from their operating tariffs — the legally binding rate and service documents filed with and approved by the Maine Public Utilities Commission (MPUC). These tariffs authorize utilities to take specified actions against customers who violate conservation orders, including issuing fines and, in extreme cases, restricting or terminating service.

Typical penalty structures for publicly owned water utilities in Maine follow a progressive escalation. A first violation generally results in a written warning, delivered by mail or sometimes posted at the property. A second violation within the same restriction period commonly carries a fine in the range of $50 to $100. A third or subsequent violation can result in fines of $150 to $250 per incident, and persistent noncompliance may trigger a flow restrictor installation — a device fitted to the service line that limits the rate of water delivery to the property without fully terminating service.

Complaint pathways in Maine typically begin with neighbor reports or utility staff observation. Many Maine utilities do not yet deploy full smart-meter networks capable of real-time consumption monitoring, though the Portland Water District has made significant progress in advanced metering infrastructure (AMI) deployment across its service area. AMI allows the district to detect anomalous overnight usage patterns that might indicate irrigation running outside permitted hours, flagging accounts for follow-up investigation without requiring staff to physically observe the violation.

Smaller Maine utilities, particularly those serving rural communities, rely more heavily on visual observation by distribution system operators during their routine rounds. Staff members who observe active irrigation violations during restricted periods are authorized to document the incident, issue a verbal or written warning, and initiate the formal notice process through the utility's customer service office.

Appeals of penalties in Maine are first directed to the utility's customer service department. Customers who dispute a fine or enforcement action and cannot resolve it at that level may escalate to the MPUC's Consumer Assistance and Safety Division, which has jurisdiction over consumer complaints against regulated utilities. The MPUC does not typically become involved in individual restriction violations, but its oversight role provides a backstop avenue for customers who believe an enforcement action was arbitrary or erroneous.

Municipal water departments that are not rate-regulated by the MPUC — primarily those operated directly by town governments rather than incorporated water districts — derive enforcement authority from local ordinance. Violations in those systems are adjudicated through the district court system if the customer refuses to pay assessed penalties.

HOA protections in Maine

Maine does not have a statute that explicitly preempts homeowners association landscaping rules in favor of water conservation activities in the same sweeping fashion as states like California, Texas, or Colorado have enacted. However, Maine's legal framework provides meaningful context for understanding the relationship between HOA rules and water use during drought conditions.

Maine's primary statute governing homeowners associations for condominium communities is the Maine Condominium Act, 33 M.R.S. §§ 1601-101 et seq. For non-condominium planned communities, the Maine Planned Residential Development Act and recorded declaration documents control the relationship between the association and individual lot owners. Neither of these frameworks contains express provisions overriding HOA landscaping aesthetic requirements when a public water utility imposes mandatory conservation restrictions.

However, Maine courts have recognized a general principle that private contract provisions — including HOA covenants — cannot compel performance that requires a party to violate a lawful government order. When a Maine water utility activates mandatory Stage 2 or Stage 3 restrictions under an approved water shortage response plan filed with the MPUC, those restrictions carry the force of a regulatory order. A homeowner who allows their lawn to brown in compliance with a water utility's mandatory restriction order would likely have a strong common-law defense against an HOA attempting to enforce a green-lawn maintenance covenant under those circumstances.

As a practical matter, Maine HOAs have not generated significant reported litigation or regulatory action around this issue, likely reflecting the state's relatively infrequent imposition of serious water restrictions. The Maine Common Interest Ownership Act, which governs associations formed after 1984, requires that association rules be reasonable and applied consistently — a requirement that courts could use to scrutinize enforcement of appearance-based landscaping rules during a declared water shortage.

Residents of HOA communities who face pressure to maintain irrigation during a utility restriction period should first review their declaration's specific language regarding landscaping obligations. If the declaration includes a clause that the association's rules cannot require a unit owner to violate applicable law or government order, that language would provide direct protection. Maine residents may also contact the Maine Attorney General's Consumer Protection Division if they believe an HOA is acting unreasonably or in bad faith in enforcing landscaping requirements during a declared water emergency.

The absence of an explicit Maine statute on this topic means that residents and HOAs alike operate in a zone of some ambiguity, and the Legislature could clarify the law — as several other states have done — to expressly protect homeowners who allow drought-dormant lawns during utility-declared water shortages.

Where Maine gets its water

Maine is extraordinarily rich in freshwater, possessing more than 6,000 lakes and ponds, 32,000 miles of rivers and streams, and a deep glacially sculpted landscape that recharges groundwater prolifically. This abundance shapes where and how Maine communities obtain their drinking water supplies.

Sebago Lake, located in Cumberland County about 20 miles northwest of Portland, is the crown jewel of Maine's public water supply infrastructure. At roughly 45 square miles in surface area and with a maximum depth exceeding 300 feet, Sebago Lake holds an enormous volume of extraordinarily clean water. Portland Water District draws its supply directly from Sebago, treating it minimally compared to what would be required for a more turbid source. The lake's watershed encompasses the Sandy River inlet and multiple tributary streams draining the Sebago Lake basin. The federal EPA has granted Sebago a surface water treatment technique waiver — one of only a few such waivers in the Northeast — because of its exceptional natural water quality.

The Penobscot River, Maine's second-largest river system and one of the most ecologically significant rivers in the northeastern United States, provides the hydrological backbone for water supply in central and eastern Maine. Bangor Water District draws on impoundments within the Penobscot watershed, including Floods Pond near Ellsworth and storage reservoirs in the hills of Otis. The Penobscot drains an enormous swath of central Maine, receiving flows from the West Branch, the East Branch, and tributaries like the Piscataquis River and the Mattawamkeag River.

The Kennebec River, running southward through Augusta and into Merrymeeting Bay, serves communities including Augusta and Waterville. The Kennebec's watershed extends far into the western mountains of Maine and benefits from the high precipitation that falls across the Longfellow Mountains. Cobbosseecontee Lake in Kennebec County and Messalonskee Lake in Somerset County also contribute to regional water supply in that corridor.

In southern Maine, the Saco River and its tributaries drain the foothills of the White Mountains on both sides of the Maine-New Hampshire border. Communities in York County and parts of Cumberland County depend on wells and surface withdrawals tied to this watershed. Groundwater from glacial outwash plains along the Saco and its tributaries, particularly the Ossipee and Little Ossipee Rivers, supports private wells and some small public systems.

Snowpack in western Maine's mountains — particularly in Oxford and Franklin counties, where elevations exceed 4,000 feet on peaks like Sugarloaf and Old Speck — plays a genuine role in spring recharge of streams and shallow aquifers. Spring snowmelt typically drives reservoir refill events in April and May, setting baseline storage levels for the summer season. This makes late-winter snowpack readings in the western highlands a meaningful early indicator for summer water supply conditions.

Groundwater is critically important in rural Maine, where roughly 40 percent of the population relies on private wells tapping bedrock fractures or surficial sand-and-gravel aquifers. The fractured crystalline bedrock aquifer that underlies much of the state varies considerably in yield, with the most productive zones found along fault lines and in areas of granite intrusion.

How Maine's drought framework works

Maine does not operate a standalone statewide drought management agency with its own dedicated statute. Instead, drought monitoring and response in the state flows through a coordinated network anchored by the Maine Geological Survey, the Maine Emergency Management Agency (MEMA), and the Maine Drinking Water Program within the CDC. These agencies share data and consult with federal partners, particularly the U.S. Drought Monitor, which is produced jointly by the University of Nebraska-Lincoln, the National Oceanic and Atmospheric Administration, and the U.S. Department of Agriculture.

The U.S. Drought Monitor categorizes drought conditions on a five-step scale: D0 (Abnormally Dry), D1 (Moderate Drought), D2 (Severe Drought), D3 (Extreme Drought), and D4 (Exceptional Drought). Maine has historically rarely exceeded D2 in isolated pockets, and large-scale D3 or D4 conditions are essentially unprecedented in the modern observational record. The monitor updates every Thursday, and Maine water managers watch these weekly releases closely during the dry summer months of July and August.

At the utility level, individual water districts set their own conservation stage frameworks. Portland Water District, for example, maintains a multi-stage water shortage response plan that is triggered by Sebago Lake elevation readings and projected demand curves. Stage 1 typically involves voluntary requests for a 10 percent reduction in use. Stage 2 activates mandatory outdoor watering restrictions, limiting irrigation to specific days and hours. Stage 3 prohibits most outdoor water use entirely and may restrict certain commercial and industrial processes. Stage 4 represents a severe emergency requiring coordination with the Maine Drinking Water Program and potentially MEMA.

Trigger metrics at the Portland Water District include Sebago Lake elevation relative to historical norms for the date, the number of consecutive days below a defined threshold, and a 90-day precipitation deficit calculated from the National Weather Service office in Gray, Maine. The Bangor Water District uses a comparable framework tied to storage readings at its Floods Pond and other impoundments in the Lucerne watershed.

Maine's Drought Task Force, an informal interagency working group, convenes during periods of abnormal dryness to coordinate communications, share monitoring data, and advise the Governor's office on whether any executive action is warranted. The task force does not have permanent statutory standing but has convened several times in response to notable dry periods, including the 2001-2002 drought and the summer dryness of 2016. Its members typically include representatives from the Maine Geological Survey, the Maine Department of Agriculture, Conservation and Forestry, the Maine Forest Service, and key public water utilities.

Groundwater levels measured at index wells throughout the state serve as additional trigger indicators. The Maine Geological Survey maintains a network of observation wells, and readings at sites like the Kennebec County monitoring well near Augusta or the Oxford County index well provide early signals of aquifer stress before surface water deficits become critical.

Conservation programs in Maine

Maine offers a layered landscape of water conservation programs delivered through state agencies, regional water utilities, and federally funded rural assistance programs. These initiatives operate even when no restrictions are in force, reflecting the view that conservation investment during normal conditions prevents emergencies during dry ones.

Portland Water District's WaterSmart Program provides residential customers with free water use reports benchmarked against comparable households, along with personalized conservation tips delivered through the district's online customer portal. The district has distributed free WaterSense-certified showerhead kits valued at approximately $25 to $35 per kit to residential customers through periodic promotional campaigns. The kits typically include a high-efficiency showerhead, faucet aerators, and leak detection dye tablets. Portland Water District customers may also request a free indoor water use audit, in which a district representative visits the home to evaluate toilet performance, identify leaks, and assess appliance efficiency.

The Maine Rural Water Association (MRWA) operates a technical assistance program funded in part through a cooperative agreement with the U.S. Environmental Protection Agency. MRWA provides on-site assistance to small and rural water systems throughout Maine, helping them develop water loss control programs, identify distribution system leaks, and implement conservation pricing structures. For very small systems struggling with aging infrastructure, MRWA's assistance is often the primary pathway to reducing system-wide water losses.

The United States Department of Agriculture's Rural Development Water and Environmental Programs offer grants and low-interest loans to rural Maine communities for water system improvements, including infrastructure that reduces transmission losses. Several Maine towns have received USDA Rural Development funding in recent years for water main replacement projects that have cut system-wide water loss percentages significantly.

The Maine Department of Environmental Protection administers a voluntary water efficiency standard for large water users under its site location of development program. Commercial and industrial facilities above certain thresholds are encouraged to implement best management practices for water use and to document their water balance as part of facility permitting.

Bangor Water District offers rebates of up to $100 for customer replacement of older, high-flow toilets with WaterSense-certified models using 1.28 gallons per flush or less. The district's conservation program also provides free residential leak detection kits upon request, including dye tablets for toilet testing and illustrated guides to reading water meters to identify overnight losses.

The Maine State Housing Authority (MaineHousing) incorporates water efficiency standards into its weatherization and home energy assistance programs, through which eligible low-income households receive plumbing fixture upgrades including low-flow aerators and showerheads at no cost. Approximately 3,000 to 5,000 Maine households receive weatherization services annually, and plumbing efficiency improvements are a routine component of those visits.

Lawn care in Maine's climate

Maine sits firmly in the cool-season turfgrass zone, a climate classification that fundamentally determines what grass species thrive, how they should be managed seasonally, and how they respond to summer stress. Understanding this framework helps Maine homeowners maintain healthy turf with minimal supplemental irrigation, even during dry periods.

Kentucky bluegrass (Poa pratensis) is the dominant fine-lawn species across most of Maine. It produces a dense, attractive turf with excellent cold hardiness — an important trait in a state where frost can arrive in September in northern counties and ground freezing extends deep through the winter. Kentucky bluegrass has a moderate drought tolerance but goes summer-dormant readily during July and August dry spells, turning straw-brown. This dormancy is a survival adaptation, not death, and the grass reliably greens up when cooler temperatures and fall rains arrive. Maine homeowners who allow their Kentucky bluegrass lawns to go dormant during a hot, dry August are making an ecologically sound choice that requires no rescue watering.

Fine fescues — including creeping red fescue (Festuca rubra), Chewings fescue (F. rubra ssp. commutata), and hard fescue (Festuca brevipila) — are increasingly popular in Maine, particularly in shaded areas and on low-maintenance sites where fertilization and irrigation are minimal. Fine fescues genuinely tolerate drought better than Kentucky bluegrass on a shallow-soil basis and are well suited to the sandy, low-fertility soils found across much of coastal and central Maine.

Tall fescue (Festuca arundinacea), historically less common in Maine because of its marginal winter hardiness at the northern edge of its range, has gained ground in southern Maine as winters have moderated. Improved turf-type tall fescue varieties marketed as "Rebel" and "Jaguar" types offer deep root systems that improve drought access and maintain green color longer into summer dry spells than shallower-rooted Kentucky bluegrass.

Perennial ryegrass (Lolium perenne) is frequently included in Maine seed mixes for its fast germination and establishment, but it lacks the cold hardiness and drought tolerance of bluegrass and fescue and is best treated as a companion species rather than a primary lawn component in most of the state.

Maine's University of Maine Cooperative Extension recommends mowing cool-season lawns at a height of three to four inches throughout the summer — a critical water conservation practice, since taller grass shades soil, reduces surface evaporation, and encourages deeper root development. Leaving clippings on the lawn returns nitrogen to the soil, reducing fertilizer requirements and maintaining soil moisture-retaining organic matter.

Drought history and 2026 outlook in Maine

Maine's climate makes catastrophic, multi-year droughts unusual, but the state has experienced notable periods of water stress that have tested its infrastructure and driven lasting changes to water management policy and practice.

The drought of 2001-2002 was the most significant water supply emergency in Maine in recent memory. Precipitation deficits that began building in the summer of 2001 intensified through the following winter and into 2002. Sebago Lake dropped to historically low elevations, and Portland Water District issued its first mandatory water restrictions in decades, limiting outdoor irrigation and asking large commercial customers to reduce consumption. Several smaller community water systems in Oxford and York counties activated emergency interconnections or sought emergency supply agreements with neighboring utilities. The Saco River recorded some of its lowest late-summer flows in the period of record at the USGS gauge near Cornish.

The summer of 2007 brought a more localized but acute drought to parts of Aroostook and Washington counties in northern and eastern Maine. The St. John River watershed and the Machias River basin saw precipitation deficits that stressed agricultural irrigation for potato farmers and triggered voluntary conservation appeals from several small water systems. Fish mortality events in certain tributaries were reported by the Maine Department of Inland Fisheries and Wildlife.

In 2016, a significant summer drought affected much of southern and coastal Maine. York County experienced some of the most severe conditions, with the U.S. Drought Monitor classifying portions of the county at D2 (Severe Drought) through much of July and August. Groundwater levels in sand-and-gravel aquifers along the Saco and Mousam River corridors fell notably, affecting private well yields for some rural residents. Several municipalities issued voluntary conservation requests. The Mousam Lake and Great East Lake watersheds received particular attention from water managers during this period.

The fall drought of 2020 was unusual in its timing and geographic scope. Following a dry late summer, soil moisture deficits intensified through October and November across much of central and western Maine. The Kennebec River at Augusta recorded below-normal flows for an extended period, and Cobbosseecontee Lake fell below median levels for the date. The event resolved with substantial precipitation in late November and December, avoiding a sustained water supply emergency.

The hydrological baseline entering 2026 is favorable across virtually all of Maine. Reservoir storage at Sebago Lake, Floods Pond, and the Kennebec Water District's impoundments stands at or above seasonal norms following adequate fall and winter precipitation. Groundwater levels at the Maine Geological Survey's index monitoring wells are within normal ranges, suggesting healthy aquifer recharge over the preceding months.

NOAA's Climate Prediction Center seasonal outlook for the summer of 2026 does not indicate elevated drought probability for the northeastern United States, though probabilistic climate forecasts carry inherent uncertainty at seasonal timescales. The primary variable to watch in Maine this season is the July-August precipitation pattern. Maine's climate delivers most of its summer rainfall through convective thunderstorm activity, which can be spatially uneven — a wet July in Portland does not guarantee adequate rainfall in Aroostook County or the Downeast coast.

Water managers at Portland Water District will closely track Sebago Lake elevation weekly throughout the summer, comparing readings against the historical percentile record dating back to the early twentieth century. If the lake drops below the 25th percentile elevation for consecutive weeks during July or August, voluntary conservation messaging typically begins, and Stage 1 consideration moves onto the agenda.

Climate trend data for Maine shows a gradual increase in the frequency and intensity of summer dry spells even as annual precipitation totals remain broadly stable or slightly increasing. The state's coastal areas are experiencing warmer and longer summers, which elevate evapotranspiration demand and can translate modest precipitation deficits into more serious soil moisture stress than would have been expected from the same deficits in a cooler climate.

Residents with private wells in the sandy plains of York County and along the Androscoggin River valley in Androscoggin County should be particularly attentive to well yield during any sustained dry period, as shallow sand-and-gravel aquifers in those areas can respond relatively quickly to precipitation deficits. The Maine Geological Survey's drought monitoring page provides updated groundwater level data that private well owners can use as an early warning resource.

Frequently asked questions about Maine water restrictions

Are there any water restrictions currently active in Maine?

No. As of 2026, there are no active water restrictions — mandatory or voluntary — in effect anywhere in Maine. Both Portland and Bangor, the state's two largest cities, are operating under normal, unrestricted water service conditions. The absence of restrictions reflects adequate precipitation over the preceding months and healthy reservoir and groundwater levels across the state. Residents should continue to practice reasonable water efficiency as a baseline habit, but no regulatory limitations on water use are currently in force.

Who declares a water emergency in Maine?

Maine does not have a single statewide authority that issues universal water emergency declarations. Individual water utilities — including incorporated water districts like Portland Water District and Bangor Water District, as well as municipal water departments — activate their own shortage response plans based on internal trigger metrics such as reservoir elevation or 90-day precipitation deficits. The Maine Drinking Water Program within the CDC may provide guidance and coordination support, and the Maine Emergency Management Agency can become involved if a shortage threatens public health at a scale requiring executive branch response. The Governor's office has authority to issue emergency orders under Maine's Civil Emergency Preparedness Act, 37-B M.R.S. § 742, though this has not been invoked specifically for water supply in recent decades.

Does Sebago Lake ever run low enough to affect Portland's water supply?

Sebago Lake's enormous volume provides a substantial buffer against short-term precipitation deficits, but it is not immune to extended drought impacts. During the 2001-2002 drought, the lake dropped to notably low elevations and Portland Water District imposed mandatory restrictions for the first time in many years. The lake's elevation is monitored daily, and the Portland Water District publishes current and historical readings publicly. Because the lake's watershed encompasses a large area in southern Oxford County and northwestern Cumberland County, it typically recovers well from a single dry year as long as the following winter and spring deliver near-normal precipitation. Multi-year droughts, which are less common in Maine's climate than in the Southwest, pose the most serious risk to Sebago Lake storage.

Can a Maine HOA fine me for not watering my lawn during a drought?

This situation has not been definitively resolved in Maine statutory law, but the practical legal risk to homeowners who conserve water during a utility-declared mandatory restriction is very low. When a Maine water utility activates mandatory restrictions under its MPUC-approved tariff, those restrictions carry regulatory authority. HOA covenants requiring lawn maintenance are private contractual obligations, and courts generally do not enforce private contracts in ways that require violation of lawful government orders. Homeowners in this situation should document the utility's restriction notices, keep copies of any HOA communications, and if the HOA pursues enforcement, consult with a Maine attorney familiar with common interest community law. The Maine Attorney General's Consumer Protection Division can also provide general guidance on HOA conduct.

How do I know if my private well is affected by drought conditions in Maine?

Private well owners do not receive utility notifications, so monitoring falls entirely on the homeowner. Signs of drought stress on a private well include declining water pressure, the pump cycling more frequently than usual, air or sediment in the water, and complete loss of yield. Maine homeowners can proactively track drought conditions through the Maine Geological Survey's groundwater monitoring network, which publishes current depth-to-water readings at index wells around the state on its website. USGS stream gauge data for rivers like the Saco at Cornish, the Androscoggin at Auburn, and the Kennebec at Augusta provide complementary indicators of regional water table conditions. If a private well begins showing stress symptoms, reducing household water use and consulting a licensed Maine well driller for an assessment are the recommended first steps.

What rebates are available for water-efficient fixtures in Maine?

Rebate availability varies by utility. Bangor Water District offers rebates of up to $100 for WaterSense-certified toilet replacements. Portland Water District has distributed free water efficiency kits including WaterSense showerheads through its WaterSmart Program. Low-income Maine households may receive free fixture upgrades through MaineHousing's weatherization program at no cost. Residents should contact their specific water utility directly to ask about current rebate offerings, as programs change annually and are sometimes limited to specific appliance categories or customer income levels. The EPA's WaterSense program website also maintains a searchable rebate finder tool that includes Maine utility offerings.

What are the best grasses to plant in Maine to reduce irrigation needs?

Fine fescue blends — particularly mixes of creeping red fescue, hard fescue, and Chewings fescue — offer the best combination of drought tolerance, cold hardiness, and low maintenance in Maine's cool, humid climate. These species establish well from seed, tolerate shade and infertile soils, and require significantly less supplemental watering than Kentucky bluegrass once established. For full-sun lawns where a denser, finer texture is desired, selecting Kentucky bluegrass cultivars bred for improved drought tolerance — such as those in the "Midnight" or "Reveille" lineages — can help reduce irrigation frequency. University of Maine Cooperative Extension publishes updated turfgrass variety trial results for the state and can help residents select cultivars appropriate for their specific location, soil type, and maintenance expectations.

How often does Maine actually impose mandatory water restrictions?

Mandatory restrictions are rare in Maine's recorded history. The most significant modern example occurred during the 2001-2002 drought, when Portland Water District activated mandatory outdoor irrigation limits tied to low Sebago Lake levels. Isolated smaller systems have activated restrictions during intense localized dry spells, including some communities in York County during the 2016 summer drought and a handful of northern Maine systems during the 2007 drought event. Across the broader sweep of the state's water utility history, most years pass without any utility reaching Stage 2 mandatory restriction levels. This favorable record reflects both Maine's generally adequate precipitation and the large storage capacity of major surface water sources like Sebago Lake and the Penobscot watershed impoundments.
