Spencer Drawdown Reservoir Sediment Flush (Abbreviated Version)
Spencer Dam filled with sand within a couple decades of construction int he 1920s. After that, it flushed sediment twice a year to make room for hydropower operations. Dr. Paul Boyd recorded a time lapse video of the first day of the flush in 2014.
We talk about this operation on season 2 of the RSM River Mechanics Podcast, which is dedicated to Reservoir Sediment Management:
