This is a photo of a dam in the lower Yakima River. Efforts to ameliorate the negative effects of diversion dams on aquatic species of concern are important in rivers where water withdrawal supports agricultural economies, and they are likely to become increasingly important with impending climate change. 

Estimated relationship between entrainment probability and proportion of river flow entering canals at Wapato Dam, Sunnyside Dam, and Prosser Dam on the Yakima River, Washington. The relationships are shown at the mean total river flow for (A) yearling Chinook Salmon, (B) juvenile steelhead, and (C) subyearling Chinook Salmon.

Survival probability estimates and 95% confidence intervals for yearling Chinook Salmon, juvenile steelhead, and subyearling Chinook Salmon at three diversion dams on the Yakima River, Washington.
