Fish entrainment is the loss of fish whenever streams, creeks or rivers are diverted for irrigation and other uses. Fish follow the diversion of water to a location that isn’t ideal for survival. It’s one of the major causes of fish loss in Wyoming and around the country. What generally happens is that trout and other fish will move out of their ideal habitat, like the river, into irrigation systems and end up diverted into a field or becomestranded and die.

The Wyoming Game and Fish Department works to keep fish in the river where they belong by installing fish screens or other bypass structures on water sources around the state. This gives fish a chance to continue their movement up and down streams freely, thereby conserving the resource for anglers without loss of irrigation water to agricultural producers and other uses.
