To potentially avoid tying up bulkhead gateslots with an STS, a fish screen slot (FSS) was designed and built into the dam (Fig.
In conjunction with project operations, the Bureau has installed a fish screen on a major diversion canal, built a fish ladder to restore upstream movement of endangered shortnose and Lost River suckers (Chasmistes brevirostris and Deltistes luxatus, respectively) into Klamath Lake, and removed a dam on an upstream tributary to facilitate sucker spawning.
One of the most costly projects is the $6 million Feather River fish screen, which is funded by Department of Fish and Wildlife, and Fish and Game grants and Yuba City's water fund.
There is insufficient evidence to reject the overall irrigation fish screen model for lack of fit (Hosmer and Lemeshow, p = 0.737).
In the last year alone, irrigators provided 60,000 acre-feet of water for endangered species, and the Klamath Irrigation District helped complete a state-of-the-art fish screen that will prevent the destruction of 1 million endangered suckers each year.
The Freeman Diversion includes a two-entrance denil fish ladder, a fish screen, and by-pass facilities to provide anadromous fish passage upstream and downstream of the diversion facility.
For downstream fish passage, EWEB would shut Carmen-Smith's secondary power plant at Trail Bridge, allowing fish to use its spillway rather than constructing a floating fish screen and a nearly mile-long transport pipe.
But instead of a complicated "volitional" system that included an expensive fish screen and ladder as originally proposed, the parties have agreed to an alternative method of fish passage.
On Saturday, EWEB will begin draining the power canal so workers can perform regular maintenance on it, the power plant and fish screen. The shutdown of the power plant and canal is expected to last about two weeks.
