Conveyance Losses Due to Reservoir Releases
Abstract
Three natural streams in Wyoming were studied in
order to estimate incremental conveyance losses
associated with incremental increases in stream flow.
For each study area, all surface water inflow and outflow
was measured before, during and following a
significant reservoir release. With this data, conveyance
losses were determined for the control period
using a water budget analysis. The major losses were
attributed to bank storage and a decrease in groundwater
inflow. The conveyance loss results for the
three study areas ranged from 0.34 to 1.66 percent per
mile. Duration of release, of five times (3 days to 15
days), resulted in a decrease of the conveyance loss by
over 50 percent (0.76 to 0.38 percent per mile).
