According to Salt River Project: Maintenance work at Mormon Flat and Horse Mesa dams will result in lower water levels at Canyon Lake between Sept. 29, 2007 to Jan. 26, 2008. SRP will gradually draw down Canyon Lake to about 50 feet below the normal level. The marina will be relocated 1.1 miles from its current location during the drawdown and then will be moved back to the existing location when the project is completed. Because of safety concerns and the smaller capacity of Canyon Lake, the lake will be closed to all recreational boating during the majority of the drawdown.
