Sebago-Ossipee Hills and Plains

The Maine Emergency Management Agency received 156 reports of dry wells in 2026 as of October 15, up from 39 reports on September 3, a fourfold surge in just six weeks. Many households in the Sebago-Ossipee region and throughout York County are relying on laundromats and gyms for water, and well-drilling services have extended wait times to December 2026 or spring 2027, leaving families without stable home water supplies through the fall and winter.

Sebago-Ossipee Hills and Plains sits at the intersection of FEMA flood zones AE (a 1% annual chance floodplain) and Zone X (outside mapped flood hazard), including 3 polygons in the regulatory floodway where development is most restricted. The area contains 8 GAP 1 and 2 protected lands managed primarily for biodiversity by state and nonprofit organizations, plus 77 GAP 3 areas open to extraction, and is partly within Vernon S. Walker Wildlife Management Area and Waterboro Barrens Preserve.

Northern York County remains in severe drought, with water levels near record lows and groundwater below normal. The area stretching from northern York County south to Hancock County has been in severe drought for multiple weeks and showed no change in the latest Drought Monitor update. Wells continue to run dry across the region.

Severe drought (D2+) covers 33.83 percent of York County as of the week ending October 26, unchanged from mid-September. The rapid intensification the team observed in early September has halted; every acre of the county remains in at least moderate drought. October precipitation is running 1.5 inches below normal, sustaining the dry conditions that drove the earlier drought expansion.

The 3-month precipitation total ending September 2026 was 8.5 inches for York County, 1.8 inches below the 1901-2000 average of 10.3 inches, ranking as the 31st driest of 132 such periods on record. This confirms the dry summer and early autumn continue to stress water supply in the region.

October precipitation at Hollis, Maine totals 1.5 inches through October 22, running 1.5 inches below normal for this date. The shortfall continues the dry pattern established over the summer and early fall, keeping soil moisture depleted as autumn enters its driest months.

Northern red oak showing ripe fruits, recent fruit drop, and colored leaves observed on 2026-10-10 in the Sebago-Ossipee area. This timing is at the early end of the typical October 12-28 peak-color window for southern Maine coastal and lake regions, where oaks generally hold their green longer than earlier-turning species like maples and birches.

A third of York County, Maine is now in severe drought, and it got there in two weeks. On the drought map for the first week of September, severe drought covered a sliver of the county too small to register. By the September 8 map it covered about a quarter. On this week's map it covers 34 percent, and every acre of the county is now in at least moderate drought. No part of the county has reached extreme drought. The deficit that built this was July's. Averaged across the county, July brought 1.4 inches of rain, 2.2 inches under the 1901-2000 average and the fifth-driest July in a record that runs back to 1895. June had been wet, about an inch above its average. August came in eight-tenths of an inch short. The summer as a whole ran two inches under the long-term average for the county. The lag between a dry July and a severe-drought map in September is what sand does. The Ossipee and Sebago plains sit on glacial outwash, deep sand and gravel that stores rain and feeds it slowly to streams and ponds. That storage kept streams flowing through August. It is now drawing down, and the kettle ponds, which have no inlet stream and sit directly on the water table, drop with it. Brook trout meet this at spawning. They begin once water cools below about 48 degrees Fahrenheit, usually from late September on, and the females do not dig nests just anywhere. They choose gravel where groundwater seeps up through the bed, because that upwelling keeps the eggs oxygenated through the winter. Work on a Cape Cod outwash stream, the closest geological match to these plains, found trout returning year after year to a small set of seeps at meander bends where the flow was strongest and carried the most oxygen. A falling water table shrinks that set of usable seeps. Low water can also keep fish from reaching them at all, and fish held in shallow stagnant reaches under direct sun have nowhere cooler to go. The leaves now dropping into the streams are the winter food base. In normal flow, most leaf litter is chewed up by shredding insects, stoneflies and caddisflies among them. In an experimental study published last year, low flow cut total leaf breakdown by 39 percent and shredder densities by 73 percent. Where fine sediment had settled into the channel, clogging and low oxygen also shut down the streambed refuges those insects retreat into during drought. Sandy outwash channels collect exactly that kind of fine sediment as flow drops. On the uplands the same dryness reads as fuel. The Waterboro barrens grow pitch pine and scrub oak over as much as ninety feet of sand that sheds rain in hours, and their cured grass and dropped oak leaves respond to days of dry weather, not weeks. That barrens burned in 1947 and has not burned in wildfire since. Statewide, the 1947 fire season followed a wet spring, drought that set in during July, and ground that was dry by the end of September. Maine's Forest Service posts a daily fire danger rating by region through late November, and burn permits stop in any region rated high. The next weekly drought map will show whether severe drought keeps spreading across York County. At the pace of the last two weeks, it has room to.

There is a carnivorous plant drifting in the small ponds of the Ossipee and Sebago country, and almost nobody who swims past it knows it is there. Purple Bladderwort (*Utricularia purpurea*) has no roots at all. It floats free just under the surface as a loose tangle of fine submerged stems, and strung along those stems are hundreds of hollow bladders, each one only a couple of millimeters across. Every bladder is a trap, and it works by suction. Glands in the bladder wall pump water out until the inside is held under negative pressure, with a small door sealed watertight against that pressure. On the outside of the door sit mechanosensory bristles. When a swimming animal brushes one, the bristle flexes, the door inverts from convex to concave, and at that instant it can no longer hold; it springs, and the inrush of water carries the animal inside. It is one of the fastest movements known in the plant kingdom. The rootlessness is the reason for all that machinery. With no roots to draw nitrogen and phosphorus from the sediment, the plant has to take them from the water column, and the bladders are how it does it, catching zooplankton and other microinvertebrates. That fits where the species turns up: nutrient-poor pond and lake margins, the tea-colored, low-fertility water this glaciated country is full of. Purple Bladderwort then complicates its own story. Its traps are not sterile prey chambers. They hold a dense resident community of algae, ciliates and bacteria, and the literature on this species suggests it has partly relaxed its reliance on catching and digesting animals, drawing instead on what lives inside the bladders. Darwin was already looking into those traps and finding tenants. Twenty-six records have been logged in the surrounding ponds and lakes over the past two years, and they cluster in late summer: three at Chocorua on August 17 of this year, one at West Newfield across the Maine line on August 15, and three at Sebago on August 14 the summer before, with another at Naples on August 9. It is a native plant here and carries no federal listing. To find it, wade a quiet pond edge, lift a strand of submerged stem out of the water, and look closely at what is hanging off it.
