From the Sky-Hi Daily News:
The increased flows are designed to restore channel conditions favorable to trout after an August silt removal project by Windy Gap’s owner, Northern Water’s Municipal Subdistrict. The project required lowering the reservoir’s level, which increased sediment flow into the river below the dam. Biologists predict a “flushing flow” beginning Wednesday morning will assist in clearing sediment prior to the brown trout spawn in mid-October.
“Despite taking numerous precautions to minimize the amount of sediment moving downstream of Windy Gap during the silt removal project, some did make its way down,” said Northern Water General Manager Eric Wilkinson. “We’re happy that we have the water available to help improve trout habitat.”
Beginning Wednesday morning, releases from the dam will increase the river’s flow to 450 cubic feet per second. Outflow from the dam will then be stepped down through Friday, returning the river to normal seasonal levels. The Colorado River near Parshall is currently running at approximately 190 cfs.
