Each year, the Upper American River Project (UARP) creates a mix of scheduled and opportunistic whitewater opportunities on South Fork Silver Creek below Ice House Reservoir —one of California’s most unique, dam-controlled Class IV runs. For boaters willing to track conditions and stay flexible, the combination of planned releases and snowmelt-driven pulse flows can significantly expand the season.
In Below Normal, Above Normal, and Wet water year types, the license provides for a series of multi-day pulse flows timed with snowmelt. These are not scheduled recreation releases in the traditional sense, but they can create high-quality boating windows that often exceed base recreation flows in both duration and character. This year the water year type is Below Normal and pulse flows will begin on April 20 and last through April 25, 2026.
Day 1 – ~450 cfs
Day 2 – ~450 cfs
Day 3 – ~550 cfs
