Greybull River Diversion Structure

Big Horn County, Wyoming

Greybull Field Office

This project consisted of the removal and replacement of an old concrete radial gate diversion structure with a new concrete diversion structure that incorporated an Obermeyer Gate system.  In addition, a new concrete radial gate structure was added to the existing canal structure to get the design flow rate of 800 cfs diverted into the canal.  The project was designed in 1996.
