Wayne N. Aspinall Storage Unit. Curecanti National Recreation Area was established in 1965 with the completion of Blue Mesa Dam, which creates the largest body of water in Colorado, Blue Mesa Reservoir. Most visitors to the park are surprised and impressed by Blue Mesa Reservoir, but do not realize there are actually three large dams and reservoirs in the park. Wayne N.
