Sure, there's a lot of water out there, but only a relatively small portion of it suits bluegills for their various purposes. If you spot abandoned bluegill spawning beds along a shoreline while you're out fishing this summer, remember their locations. Unlike some other fish, bluegills will return to the same beds year after year, providing water conditions are the same. Mark the spots on a map, and you'll get a leg up on other anglers when spawning season arrives.
