 Other locations had been considered for the reservoir and dam prior to a final determination.By December, 1991 after further water studies, PWSD determined, "...that the Castlewood Canyon site [south of Parker] was the most favorable location for upstream water storage and, therefore, the two additional sites were dropped from the Water Court application.Therefore, PWSD continued with plans for building the dam and reservoir at Castlewood Canyon State Park (Ciruli and Associates, 1999)."
