2008 Seven Castles Creek Debris Flow Study
The Evaluation of the Seven Castles Creek Sediment Inflow on the Fryingpan River was initiated after an August 2007 debris flow on Seven Castles Creek that moved a large amount of sediment into the Fryingpan River. Roaring Fork Conservancy worked collaboratively with the Colorado Division of Wildlife, the Town of Basalt, the U.S. Bureau of Reclaimation, Colorado River District, and Eagle County to fund this project. Below is the report and executive summary.
2007 Report on BOR's May 2006 Ruedi Reservoir Release
At the request of Basalt citizens, Roaring Fork Conservancy initiated a study of the effects of a 2006 coordinated reservoir release flow on the lower Fryingpan River above Basalt. In the spring of 2006, the Bureau of Reclamation increased flows in the lower Fryingpan River because of above average snow pack and resulting increased run-off. The resultant peak flow of 814 cfs had not been reached for seven years. Since Ruedi Reservoir started filling in May 1968 and diversions from the Upper Fryingpan began in 1972 as part of the Fryingpan-Arkansas (Fry-Ark) Project, the magnitude, timing, and duration of flows have been altered. We looked at maximum flows (one, three, and seven-day) and monthly (May and June) averages to determine how the 2006 flows compared to the historical record and modeled data.
