North Crow Reservoir Rehabilitation Project

This project consisted of the evaluation of the overall hydrologic and structural adequacy of two dams located approximately 26 miles west of Cheyenne, Wyoming.  Probable Maximum Flood (PMF) series hydrographs were developed for each dam and associated incremental damages calculated for several PMF series floods.  Conceptual designs were then developed to address dam safety deficiencies.  Final designs were developed and construction was ini­tiated in the summer of 1993. Mr. O’Grady coordinated all U.S. Army Corps of Engineers Section 404 permitting for the project, the 404(b)(1) showing document, and wetlands mitigation, and monitoring plan.
