Study underscores need to continue investments to diversify, modernize water systems Communities that rely on surface water supplies from the American River and Folsom Reservoir must modernize and diversify their water supply, storage, and delivery infrastructure to adapt to changing weather patterns. This is the conclusion of a new study published by the U.S. Bureau of Reclamation and sponsored by several local water agencies, including the City of Roseville. The American River Basin Study analyzes how changing weather patterns will impact the timing, magnitude, and type of precipitation in the future (rain vs. snow). The American River Basin includes the American River watershed, which stretches from roughly Interstate 80 to Highway 50 and from the high Sierra Nevada to Sacramento. The study forecasts that temperatures will rise by six degrees, and the high mountain snowpack that traditionally stores water supplies until spring will be reduced by 50 percent by the end of this century. More precipitation will arrive as rain in the watershed, and the majority of water runoff will flow into Folsom Reservoir in January through March, rather than April through June. Folsom Reservoir is the major water supply source for the City of Roseville. It is managed by the U.S. Bureau of Reclamation. It is historically operated for flood control operations during the winter and as storage for snowpack runoff in the spring to meet urban and environmental needs later in the year. In light of changing weather patterns and precipitation, Roseville and other water providers are developing infrastructure better suited for collecting earlier rainfall, instead of later snowmelt and alternatives to Folsom Reservoir.

“The ARBS confirms the need for Roseville to continue our efforts to develop and diversify our local water supplies and modernize our water delivery infrastructure, particularly to address our reliance on a single intake point at Folsom Reservoir,” said Sean Bigley, assistant director of water for the City of Roseville. “Although we have adequate and reliable water supplies today, we need to plan ahead and take action to ensure we can continue to have a reliable water supply for our residents and businesses and maintain a high quality of life and a thriving economy.”
