The purpose of the flushing flow is to improve trout reproduction by flushing fine sediments from spawning gravels in the river. The flushing flow also improves insect production in the stream by opening up interstitial spaces between gravels and cobbles. The flushing flow is generally welcomed by anglers, because it provides easier wading conditions. Following the flushing flow, there is a reduction in floating algae, which is beneficial to fishermen as well as irrigation diversions. The flushing flow is being accomplished by retiming the release of water between April 1 and June 30, which results in no additional release of water from Boysen Reservoir than would be anticipated during this period.
On April 12 and April 13, 2005, flows in the river below Boysen Dam will fluctuate between approximately 1000 cubic feet per second (cfs) and 5000 cfs. On April 12 at 2:00 a.m., the release of water from Boysen Dam will be increased to 3000 cfs and at 7:15 a.m. increased to 5000 cfs for 10 hours before being gradually decreased to approximately 1000 cfs on April 13, 2005.
The public is urged to use extreme caution during this period of rapid fluctuation of flows below Boysen Dam.
