Fish Passage Efficiency (FPE, the percent of fish Fish Passage Efficiency (FPE, the percent of fish passing via non-turbine routes) at all projects was passing via non-turbine routes) at all projects was relatively high ranging from 81 to 100%. relatively high ranging from 81 to 100%.

Spill Effectiveness (percent of fish passing through Spill Effectiveness (percent of fish passing through the spillway divided by the percent of water the spillway divided by the percent of water passing through the spillway) was higher than we passing through the spillway) was higher than we anticipated for Snake River Projects and was 2-3 anticipated for Snake River Projects and was 2-3 times higher for RSW’s than spillways. times higher for RSW’s than spillways.
