Systematic Review of JSATS Passage and Survival Data at Bonneville and The Dalles Dams during...

Systematic Review of JSATS Passage and Survival Data at Bonneville and The Dalles Dams during Alternate Turbine and Spillbay Operations from 2008-2012 MARK WEILAND, BISHES RAYAMAJHI, JINA KIM, CHRISTA WOODLEY, GENE PLOSKEY, JON RERECICH1 AND BRAD EPPARD1 Pacific Northwest National Laboratory 1U.S. Army Corps of Engineers, Portland District, Portland, OR

Introduction: BON

Operation of Bonneville Dam to reduce fish injury B2 operation at low to mid range of 1% peak efficiency

Improve conditions for guided fish in the gatewell May result in unfavorable conditions for turbine passed fish

B1 increase flow to offset reduced discharge at B2

Compare survival within to above the 1% operating range Best operating point (range) as identified by TSP

Spillway survival variability

Erosion of stilling basin or ogees in several spill bays and accumulation of rock

2

Objectives: BON

Analyze 2008-2012 JSATS and operations data to examine survival rates for juvenile salmonids at BON

B2 Turbine Survival Comparison:

Examine survival for fish passing turbines operating across the 1% peak efficiency range

B1 Turbine Survival Comparison:

Examine survival for fish passing turbines operating within the 1% peak efficiency range and above the upper limit of the 1% operating range

Bonneville Spillway:

Examine spillway survival by spillbay with focus on those bays where erosion of the ogee or stilling basin immediately downstream had occurred

3

Methods: BON

B1 turbines Lower quarter of 1% efficiency (Q1) Lower middle quarter of 1% efficiency (Q2) Upper middle quarter of 1% efficiency (Q3) 1% of peak efficiency (Q4) Best operating point/range (BOP) Above best operating point to generator limit (ABOP)

B2 turbines Lower quarter of 1% efficiency (Q1) Lower middle quarter of 1% efficiency (Q2) Upper middle quarter of 1% efficiency (Q3) 1% of peak efficiency (Q4)

Conclusions: BON

B1 There was not a difference in survival for salmonids passing within the 1% of peak operating efficiency and salmonids passing at operations above the upper 1% operating efficiency

B2 Lower survival for CH1 in Q4 range No difference in survival for STH across operating range No difference in survival for CH0 across operating range

Spillway No obvious bay affect Lower survival of CH1 and STH above 290 kcfs discharge Trend of lower survival for CH0 at low discharge levels

Introduction: TDA

Introduction High flows forced spill discharge at bays outside the new tailrace spillway wall. Concern of lower survival due to predation

Objective Examined spillway passage survival for juvenile salmonids passing on the north (spillbays 1-8) and south (spillbays 9-23) of the new spill wall at TDA
