The dominant feature within the 371 acre Lake Casa Blanca International State Park is the 1650 lake surface acre, Lake Casa Blanca.
Water based recreation activities in the park include lake swimming, boating and fishing.
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 Tips and 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 spinner baits 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.
Park facilities include restrooms with showers, picnic sites and a boat ramp.
