AFFECTED AREAS:
Rockingham County, NH
Portsmouth, NH

Start Date: 8/15/2025 -  
Water customers in Portsmouth were urged to adopt “water use efficiency measures” as little rain has fallen since May. The ongoing hot, dry conditions have driven up water use by about 5% above the July average. The public was asked to curb outdoor watering and voluntarily restrict outdoor water use between 8 p.m. and 7 a.m. Seacoast Online (Portsmouth, N.H.), Aug 15, 2025
