TRANSCRIPT

  • Yellowtail Dam Modeling Results

    Brian MarotzHydropower Mitigation Coordinator

  • Assumptions for this analysis Optimize reservoir refill during primary use period. Avoid elevations in the Flood Pool above 3640. Reduce the extent and duration of spill (>8 kcfs). Reservoir draft targets for each month, January through June, were based on water supply (April through July inflow volume). Dam discharges during fall based on similar wateryears and shaped to provide stable fisheries flows for primary river species.
