Question: Which lake is formed by Mormon Flat Dam on the Salt River?

Answer: Canyon Lake. The reservoir in the Tonto National Forest has a storage capacity of more than 57,000 acre-feet and has been a boating and fishing destination since the dam was completed in 1925. Boaters should note the calendar: The lake will close Sept. 8 for an inspection and maintenance project performed every 20 years.
