Kowalik says a 2006 survey found an excellent bluegill fishery at the lake.
"Bluegill density, growth and population balance was excellent," says Kowalik.
The survey found bluegill and redear sunfish that measured 10 inches long.
Anglers reported catching redear as long as 12 inches.
Anglers reported that crappie were suspended at depths of 12 to 15 feet during the July survey. These brush-loving fish mostly measured 7 to 10 inches long, with some specimens stretching 15 inches.
Lake John Hay is a 210-acre impoundment located about 6 miles northwest of Salem in Washington County.
Lake access includes one boat ramp. Electric outboards on boats are allowed.
A special daily or annual city boat permit is required before a boat can launch at John Hay. The permits are sold at Salem's Clerk-Treasurer's office and at the Salem Police Department office.
These offices also distribute copies of Salem's special regulations for the lake.
"Eurasian watermilfoil (an undesirable exotic plant species) is found throughout the lake, so make sure you clean your boat before entering another body of water," warns Kowalik.
