Following near record high lake levels earlier in the year, fisherman are returning to Lake Red Rock. Marion County Conservation Officer Ken Kenyon says those high levels changed fish habitat and behavior and provided less bank access for anglers. Visitors to the area for the Knoxville Nationals are encouraged to take advantage of the great fishing opportunities at Red Rock. Temporary licenses are available at the Marion County Courthouse. The fee for a one day, nonresident license is $10.50.
