April is prime time for smallmouth fishing, and the spawning season peaks at Center Hill Lake around the time the redbuds and dogwoods bloom. Anglers can cash in on some knuckle-busting action on Center Hill waters from the end of March through mid-April. Center Hill Lake is located 60 miles east of Nashville in DeKalb County and fishermen will find great camping facilities and cabins available at Edgar Evins State Park. Fishing is best when water temperatures reach 62 to 66 degrees and water levels are between 642 and 646 feet. Anglers can call the Corps of Engineers for current water conditions. At the end of October the Tennessee Wildlife Resources Commission set the minimum-length limit on Center Hill smallies at 15 inches. Suggested tackle includes jerkbaits as well as 1/8-ounce jigheads teamed with twister-tail grubs or live bait such as spring lizards. The smallmouth spawning season is short and the action furious, so get your gear ready and be prepared for skinned knuckles and some of the best smallmouth action around.
