Tonto National Forest will be closing Canyon Lake starting Sept. 8 so the Bureau of Reclamation and Salt River Project can conduct dam safety inspections and maintenance.

The water level at the lake, which is located northeast of Apache Junction, will be lowered by about 55 feet in September. SRP says this type of maintenance, which takes place every 20 years, involves equipment located underwater that is only accessible by lowering the lake level. The utility says no water will be lost in the process, it will just be stored in other reservoirs.

“It will drop about 2 feet per day until it reaches the desired level and then which will take about four weeks roughly,” said Amanda Oliver with Tonto National Forest.

That means boat launches, picnic sites, the marina and the Dolly Steamboat Lake Cruises will be closed. The town of Tortilla Flat, however, will stay open.

The entire operation is expected to take about 16 weeks to complete.
