Region 2: Sacramento, Yuba, Feather & American
Reservoirs
The Region 2 reservoir update focuses on Lake Shasta and Lake Oroville. A snapshot of current storage conditions from the Department of Water Resources is included for each reservoir. And to the right, storage levels for the current water year (dark blue) are shown alongside analog years (2018–19 and 2024–25) for context.
Precipitation
CAP model output indicates that Region 2 will receive 105-125% of normal precipitation. For Region 2, 105-125% of normal equates to 36.60-43.57”.
The regional gauge below shows the CAP forecast lower and upper bounds (36.60-43.57”), the “normal” for Region 2, and the observed precipitation through March 9. After the month’s quiet start, late-February storms boosted water year totals by 6.88 inches. February had the second-highest accumulation of the water year for Region 2, trailing only December. From February 1 through March 9, this region gained roughly 20 percentage points, bringing it to 88% of its total water year accumulation.
PLEASE NOTE: Water-year averages and accumulations are calculated using the California–Nevada River Forecast Center (CNRFC) monthly precipitation observations, which provide station-level precipitation totals across valley floor, foothill, and mountain locations. These observations are sourced directly from the National Weather Service CNRFC precipitation monitoring dataset and are used to derive regional water-year accumulations and percentages of normal for each CAP region.
