Description: Scope/Content: Abstract: Adverse effects caused by drawdown-triggered high total suspended sediment (TSS) levels have prompted a reconsideration of drawdown start-time. This update investigates alternatives to initiating the lowering process during the October low flow regime. The purpose of this analysis is to provide information that will help assess relative benefits and risks of alternative removal schedules. The analysis provides results of TSS duration, intensity, and timing by varying parameters that determine these results such as start date, historical flow records, drawdown rate, and outlet capacity. This update to that earlier report provides new analysis and responses to concerns raised by resource managers regarding the timing of reservoir drawdown under the earlier proposed dam removal scenario.
