Gray, ME – A worsening water shortage is raising concerns across Maine and New Hampshire Thursday, October 22, as meteorologists warn that recent autumn rainfall has done little to reverse deep groundwater losses threatening regional water supplies.
According to the National Weather Service NWS in Gray, Maine, the region's prolonged drought is transitioning from a meteorological drought, driven by insufficient precipitation, into a hydrologic drought affecting groundwater and water resources.
Maine Faces Rainfall Deficits Up to 24 Inches
Since the drought began in June 2025, cumulative precipitation shortages have reached 12 to 24 inches across central and southern Maine.
Neighboring New Hampshire has experienced deficits ranging from 5 to 15 inches.
Only three of the past 16 months have recorded above normal precipitation, allowing water shortages to accumulate despite occasional rainstorms.
The latest U.S. Drought Monitor, dated October 20, shows severe drought conditions across portions of Maine, with extreme drought affecting parts of the southern coastal region.
Groundwater Supplies Remain a Major Concern
While recent autumn showers have temporarily moistened surface soils, deeper groundwater storage continues to deteriorate.
The NWS estimates that portions of Maine and New Hampshire would need approximately 13 to 17 inches of precipitation over the next two months, representing 150% to 200% of normal rainfall, to significantly alleviate groundwater deficits.
Forecasters warn that approaching ground frost could eventually limit how much additional precipitation infiltrates deeper soil layers.
Residents Urged to Report Dry Wells
Officials are encouraging residents experiencing water shortages or dry wells to report conditions through state monitoring programs.
Maine residents can use the state's Dry Well Survey, while New Hampshire residents can submit reports through the state's designated reporting system.
The public is also encouraged to submit drought observations through the Condition Monitoring Observer Reports system to help improve drought assessments.
With groundwater recovery uncertain, residents relying on private wells should continue monitoring water availability and follow local conservation guidance.
