Drought — Lincoln, Maine

2025-12-01 to 2025-12-31 · Lincoln, Maine

Event narrative

Lincoln County averaged 2.02 inches of precipitation in December, approximately 2.3 inches below normal. This lack of moisture solidified the July'December period as the 2nd driest on record for the county. While coastal areas saw some snowfall, it provided negligible benefit to the deeper aquifers, which continued to decline. The USDM on December 30th classified 40% of the county in Severe Drought (D2) and 60% in Extreme Drought (D3).

Wider weather episode

December 2025 brought little relief to Maine's drought conditions, as winter took hold and frozen ground effectively halted any potential for significant groundwater recharge. While seasonal snowfall provided a surface-level coating across the state, the moisture content of the snowpack remained below normal and insufficient to offset the substantial long-term deficits carried over from the summer and autumn. Hydrological recovery remained at a standstill, with streamflows below normal, particularly in the coastal basins. Consequently, severe to extreme drought conditions persisted across southern and central Maine, with the number of failing private wells continuing to rise. By late December, it was estimated that an additional 8 to 14 inches of liquid precipitation was still required to fully restore soil moisture and replenish the state's depleted groundwater reserves.
