Idaho, Montana, and California have approximately 50,000 unscreened diversions per state
75-90% of all diversions are 5 cfs and under
Oregon and Washington have 5 screen shops total together, producing on average 81 screens per year
Current prices of screens in these states range from $3,000-$20,000 per cfs
The average producer spends between $3,000-$5,000 per year on operation and maintenance costs for screens
The average irrigation district spends between $20,000-$60,000 per year on operation and maintenance costs for screens
Fish hatcheries are in need of properly working screens to keep wild fish out of the hatchery while providing fresh water to the hatchery fish in the hatchery.
Fish Screening 101
Why do we need fish screens?
Farmers need water to grow crops. To get this water, farmers must maintain a water delivery system that can transport water from a river or lake to their farm. Since these systems travel through rugged terrain for many miles, farmers and agencies have spent decades trying to figure out a screening technology that keeps fish, sticks, and leaves from entering the canals, clogging the system, and preventing the flow of water. While maintaining these systems is costly for farmers, it has proven to be an equally large problem for fish.
What is a fish screen?
Fish screens are devices placed at diversions to prevent the fish, organic debris, and sediment that are naturally carried along in a river system from entering the diversion. In FCA’s home state of Oregon, there are an estimated 55,000 diversions supplying water for irrigation, municipal water supplies, power generation, and other uses.
