Spread Creek Fish Passage Improvement Project

QCI is working in conjunction with Trout Unlimited to provide for improved fish passage at an existing concrete diversion structure on Spread Creek.  The existing concrete diversion structure is approximately nine feet high and 120 feet long with a four to six foot head differential between the upstream and downstream sides.  The project proposal is to remove the existing structure and replace it with a series of rock weirs to maintain a maximum irrigation delivery rate of 60 cubic feet per second.  The project includes the construction of a new head gate structure, measurement devices, and 1,100 linear feet of pipeline.  A segment of the pipeline operates as an inverted siphon to facilitate an underground crossing of Spread Creek.
