This bill would extend and reauthorize a federal program that helps predict water supplies by measuring snowpack in western mountains, which is critical for planning water availability for cities, farms, and hydroelectric power plants. The program uses scientific monitoring to forecast how much water will flow into rivers and reservoirs as snow melts each spring, helping water managers prepare for droughts or floods. The reauthorization would continue funding this forecasting work that affects millions of people who depend on reliable water supplies across the West.
