Portsmouth & Pease Drinking Water Supply Update 2025 Q2

July 28, 2025

The City of Portsmouth, NH, water supply sources have recovered from the drought conditions that began in late summer 2024. The Bellamy Reservoir surface water source has rebounded from the significantly low levels recorded in September and October, aided by late winter snowmelt and spring precipitation. Groundwater levels, which were below average during the first quarter of 2025, have also returned to near-normal levels for this time of year. According to the U.S. Drought Monitor, the southeastern region of New Hampshire remains classified as abnormally dry, while the rest of the state is not currently experiencing drought conditions. The Water Division will continue to closely monitor the water supply and may implement water use restrictions if drought conditions return later this summer. Customers are encouraged to remain mindful of their water usage and to practice conservation wherever possible. For more information, go to the full 2025 Q2 Water Supply Update.
