Data and Report from S&T Project 20069: Monitoring Suspended Sediment: An Investigation Coincident with the Cherry Creek Reservoir Annual Flush

From 2017-2022, USACE, USGS, and Bureau of Reclamation (Reclamation) crews collected hydraulic and sediment data to test the capabilities and limitations of the LISST-ABS sensor, designed for suspended sediment monitoring using acoustic backscatter as a surrogate for suspended sediment concentration. The exercises were conducted during an annual reservoir flushing exercise at Cherry Creek Dam near Denver, Colorado. The instrument offers several compelling advantages, including low cost, ease of use, portability, and capability for long-term autonomous deployment. The investigation revealed challenges associated with making stable and reliable measurements; however, these drawbacks can largely be overcome through setup of a thoughtful deployment scheme and assimilation of laboratory calibration routines.

Location Information

Location Name Cherry Creek Dam
Location Description Construction of Cherry Creek Dam was completed in the early 1950s at the southeast edge of Denver in Aurora, Colo. Cherry Creek Lake, the reservoir behind the dam, lies on Cherry Creek at its confluence with Cottonwood Creek. The dam consists of an earthen embankment, an outlet structure for releasing stored water, and a spillway through which excess water can flow into the adjacent Toll Gate and Sand Creek drainage basins during times of extreme runoff from rain and snowmelt.
