Embankment Criteria and Performance Report. Cheyenne River Basin, South Dakota, Red Dale Gulch Area, Cedar Canyon Dam, Rapid City, South Dakota

摘要

Cedar Canyon Dam is located on the northwest edge of Rapid City, South Dakota, and protects a residential section of the city (Red Dale Gulch Area) from the damaging effects of swift, short duration floods. The embankment of the dam crosses a normally dry gulch (Deadmans Gulch) which lies within Cedar Canyon. The reservoir operates as a detention dam with the capacity to reduce peak discharges for floods of all magnitude. This report provides a summary record of significant design, construction, and operational data on Cedar Canyon Dam for use by engineers to familiarize themselves with the project, re-evaluate the embankment when unsatisfactory performance occurs, and provide guidance for designing comparable future projects.
