NEW-HAMPSHIRE RESERVOIR REPORT

Last Updated: January 11, 2026

As of the latest observations, New Hampshire's dams and reservoirs are undergoing their usual seasonal adjustments, with a specific point of interest regarding Lake Winnipesaukee at Weirs Beach. The gage height, a measure of the water level relative to a standard datum, stands at 3 feet, which is notably below the average of 3.77 feet. This deviation from the norm for Lake Winnipesaukee, a major recreational and ecological asset in the state, indicates that the water storage is lower than what is typically expected for this time of year. Considering that no additional source data is provided, this summary relies on the single data point available.

The lower-than-average water levels at Lake Winnipesaukee could be attributed to several factors, including reduced snowpack levels or decreased river flows feeding into the lake. These conditions may be a result of less snowfall during the winter months or earlier melting periods, which can alter the expected replenishment of the reservoir. Such changes can impact not only water availability for various uses, including domestic, agricultural, and ecological, but also affect recreational activities such as boating and fishing which are significant for the local economy. It is important to cross-reference this observation with additional datasets from local hydrological stations, weather reports, and snowpack measurements to fully understand the underlying causes and to validate the accuracy of the current conditions. Continuous monitoring is essential, as any abnormal conditions could have lasting effects on the region's water management strategies and policies.

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.
