NEW-HAMPSHIRE RESERVOIR REPORT
Last Updated: February 1, 2026
In New Hampshire, the status of dams and reservoirs is a significant concern, particularly when there are departures from typical storage levels or gage heights for the time of year. Based on the latest observations, Lake Winnipesaukee at Weirs Beach, one of the state’s major water bodies, has exhibited an unusual condition. The average gage height for the lake is historically documented at 3.77 feet, yet current measurements indicate a lower level at just 3 feet. This reduction in gage height was last observed on February 1, 2026. The discrepancy suggests a deviation from the norm that could potentially impact local ecosystems, water supply, and recreational activities.
Upon cross-referencing multiple data sources, which unfortunately haven't been provided in this query, one would explore hydrological data from local government databases, historical records, and possibly satellite imagery for comprehensive verification. The lower water levels at Lake Winnipesaukee might be attributable to a variety of factors, including below-average snowpack levels leading to reduced spring runoff, lower-than-average precipitation, or higher-than-expected evaporation rates. This anomaly in water storage could also be a reflection of upstream river flow conditions, water management policies, or long-term climate trends impacting New Hampshire's water systems. Stakeholders, including environmental agencies and water resource managers, will need to monitor these conditions closely to manage any potential adverse effects and consider mitigation strategies if the trend persists.
New Hampshire has several reservoirs and dams that serve as important sources of water supply for various purposes like hydroelectric power generation, irrigation, and recreation. Some of the major reservoirs in the state include Lake Winnipesaukee, Squam Lake, Newfound Lake, and Lake Winnisquam. These reservoirs are fed by several streams, rivers, and creeks including the Merrimack River, Pemigewasset River, and Winnipesaukee River. The snowpack from the White Mountains is a crucial source of water for these reservoirs. In recent years, New Hampshire has experienced drought conditions, leading to record low levels in some reservoirs. Seasonal trends in the area show that spring is usually the wettest season, and winter snowfall contributes significantly to the water supply. The hydrology in the area is highly dynamic and influenced by several factors like precipitation, temperature, and topography. To ensure sustainable water management, New Hampshire has implemented various policies and regulations to protect its water resources.
