This section of the South Fork of Silver Creek is significantly different in character than most
other runs in the Sierra. Its 75 feet per mile gradient is surprisingly low for a run at 5000.
The river channel is much more accessible in this section than in the steep canyons below
Junction Reservoir. The reach is also unique in that the nine-mile shuttle is actually shorter
than the 11.2-mile river reach. Most of the reach is in the area burned by the 1992 Cleveland
Fire, which diminishes the natural beauty of the run and has created wood hazards in the river.
As the trees grow back, the aesthetics of this reach will continue to improve.
If you choose to put-in at the dam (google map) the first rapid, named Pea Shooter during the flow study,
starts the run off with a bang. The water released from the base of Ice House Dam, projects a
forceful stream about 150 feet downstream of the release outlet. This makes entering the first
rapid rather exciting. Several boaters during the flow study chose to portage this rapid. Below
Pee Shooter, this first section was one of the only rapids on the run that seemed very rocky or
boney at 400cfs. Shortly below the stream flow gauge, the boaters encountered several class IV
rapids the last of which is clean on the far right. The next mile of the run is class II/III
until a short class IV section just above the beginning of the Cleveland Fire burn area at
river-mile 2.1. In this section there are two class IV rapids and one class IV+ that has several
ledges that lead into substantial hole. The next eight miles are very continuous class III with
very few distinct rapids but an amazing number of surf waves. The run changes character again at
river-mile 6, just above Chicken Hawk Springs. Here the run enters a mini gorge and there are
several large logs spanning the river. The amount of wood in the river increased throughout this
section during the flow study, particularly in the area below Chicken Hawk Springs. While it is
possible to maneuver around numerous other logs, many of these logs are quite mobile and will
continue to move from year to year. The last mile of the run contains several class IV rapids,
including a river wide ledge that is generally run on the right. Just below this final rapid is
the Bryant Springs Road Bridge. You can either take out on the right below the bridge or finished
the run by padding approximately 10 minutes across Junction Reservoir to the boat ramp area.

There is no real time gauge currently available, however, a real time gauge will be provided as part of the new settlement with SMUD.
Historical daily average flows are available from the USGS #11441500 gauge page (SF Silver Creek Near Ice House). SMUD generally keeps total control of flows in this reach. On very rare occasions high flows of over 1,000 cfs have occurred. See this Table of Flows in 1996-97. The spills of '96 & '97 were brought back to minimum releases within a few days. Minimum instream releases appear to range from about 3.3 cfs, up to about 10 cfs. Other than the minimum release, SMUD diverts the entire flow of the SF Silver Creek to the Jones Fork Powerhouse and then into Union Valley Reservoir on the main fork Silver Creek. Jones Fork Powerhouse appears to have a maximum capacity of around 260 cfs.
Boatable releases of up to 500 cfs have happened in October of some years. AW volunteers will announce releases here and on various forums when they find out about them.
