Fishing Regulations

This reservoir has special regulations on some fishes. See bag and size limits for this lake.

Angling Opportunities

The fishing at Lake Casa Blanca is very good at times. Largemouth bass fishing is good with fish up to 8 pounds common. There are many blue and channel catfish in the 2 to 4 pound range, plus a few much larger. Many large crappie provide hours of fishing pleasure. Hybrid stripers have been stocked in the lake since the late 1970's. There are currently many fish just under the 18-inch minimum length limit that will grow out to keeper-sized fish this year.

Fishing Cover/Structure

Lake Casa Blanca has rock and concrete rip-rap along dam, cattails along shoreline at normal lake level, and dead trees in the upper portion of the lake. Water levels are very low at times. Before you go, contact the park office for the current lake level.

Tips & Tactics

Look for largemouth bass in the rip rap along the dam and around structure such as flooded timber, reeds and bulrushes and underwater humps. Topwater plugs in the morning work well around the reed beds and spinnerbaits and plastic worms will do the trick later in the day, especially along the dam. Catfish are often along the dam and around reed beds and points near deeper water. Chicken liver or shad fished on the bottom is good bait for these fish. Look for crappie suspended around submerged timber and use small jigs or minnows. The hybrid stripers school around points near deep drop-offs and follow schools of shad around the lake. These open water fish can be caught trolling spoons or rattle traps, casting shad imitating lures or using chicken liver
