Construction of a screen at an irrigation diversion on Pole Creek, a Salmon River tributary in Stanley Basin and a change in the method of irrigation allowing some water to remain in the stream. Replaced in 2000 by IDFG. Surveys have estimated that the area above the Pole Creek diversion is capable of supporting 937 Chinook spawners and 563 steelhead spawners. An estimated 25 percent of the juveniles produced by these spawners would have been lost in the diversion before the screen was installed, this represents an annual loss of up to 234 chinook and 141 steelhead.
