Boysen Dam
MILLS, Wyo. – The Bureau of Reclamation, in response to a request from the Hanover Irrigation District, has scheduled a flushing flow below Boysen Dam.
“The purpose of the flushing flow below Boysen is to attempt to flush moss down river and mitigate the moss the district has at their diversion,” said Wyoming Area Manager Lyle D. Myler.
On July 10, flows in the river below Boysen Dam will fluctuate from 1,400 cubic feet per second to 4,400 cfs, and back down to 1,300 cfs according to the following schedule:

Located on the Wind River near Shoshoni, Wyoming, Boysen Dam provides irrigation, hydropower, flood control, municipal, industrial, and fish and wildlife benefits. Near Thermopolis, Wyoming, the name of the river changes from Wind River to Bighorn River. More than 60,000 acres of farmland in Wyoming receive their irrigation supply from the Bighorn River downstream of Boysen Dam.
