No economically feasible plan was formulated. DESCRIPTION: Phase I GDM studies for Arkansas River and Tributaries above John Martin Dam, CO, with emphasis on Florence, CO. Survey report dated 24 June 1968 recommended two earthfill dams and two diversion channels. The Coal Creek Dam was located on Coal Creek about 1.3 miles upstream from the Arkansas River. The other dam was Oak Creek Dam located on Oak Creek about 2.3 miles upstream from the Arkansas River.
