IV.2 - Results
Results are shown in the following figures. The scales of survival are different for each plot. Survival due to variation in flow and temperature in the Snake and Columbia headwaters are in Fig. 68, survival due to variation in fixed FGE and scaled FGE are in Fig. 69, and survival due to variation in fixed spill and scaled spill levels are in Fig. 70.
Fig. 68 Systemic flow and temperature changes. Survival from SNAKER (upper Lower Granite Pool) to below Bonneville Dam as a function of increase in flow (kcfs) at the Columbia and Snake headwaters (left) or change in water temperature (°C) (right). The horizontal line shows the base case survival for the release in 1998.
Fig. 69 Survival as a function of spill fraction held at fixed levels (left) and spill scaled by a fraction (right). The horizontal line shows the base case survival for the release in 1998.
Fig. 70 FGE at fixed (left) and scaled levels (right). The horizontal line shows the base case survival for the release in 1998.
