August A. Busch Memorial and Weldon Spring Conservation Areas

Largemouth bass are plentiful, but most are smaller than the 15-inch length limit in lakes 3, 5, 9, 10, 16, 19, 20, 22, 23, 24, 27, 30, 31, 34, 35, and 37 and Fire Lake on adjacent Weldon Spring CA. Use small spinner baits, crankbaits, and topwater baits along rocky shorelines, brush piles, and in weedy coves for best results. The best lake for big largemouth bass will again be lakes 33, 36, and 38. Lakes 6, 11, 21, and 28 and Prairie Lake on nearby Weldon Spring CA are also big bass lakes. In spring and fall, bass will be in shallow water and can be caught on spinnerbaits, jig and pig, and crankbaits. Rock on the lake dams are especially good locations to try in late winter/early spring. In the summer fish go to deeper, cooler water. Bigger bass can be caught along rock dams and drop-offs near log structures. Plastic worms, crankbaits, and jig and pigs are productive in early morning and evening hours.

White crappie are plentiful in Lake 6 and 33. Please remove all sizes of crappie up to the daily limit for the lake. Although you can occasionally catch large crappie in Lakes 6 and 33, better lakes to catch larger crappie are Lakes 19, 20, 21, 23, 30, 35, 36 and 38, and Fire Lake in Weldon Spring CA. The best crappie fishing is from mid-March through mid-May. Lakes 33 and 35 feature several large brush and pallet piles (follow the "Crappie brush pile" signs) to enhance crappie fishing. Approximately 75-100 mature cedar trees were placed along the dam and near the floating dock on Lake 33 in 2025.

Channel catfish will be best at lake 7 where catfish averaging 14 inches are stocked April through September. Lakes where channel catfish greater than 10 pounds are consistently caught include lakes 33 and 35. Lake 38 also provides larger catfish.

Flathead catfish continue to provide high-quality opportunities at Lake 33 with fish larger than 20 pounds being present. Live bait fished along the rock dams, under logs, and in root wads will produce the best results.

Blue catfish opportunities are relatively new to the Busch Area, but are developing in Lake 33. Live or cut bait may produce best results.

Bluegill larger than 7 inches should be best in lakes 6, 16, and 35, and Fire Lake on Weldon Spring CA. If you want lots of action, try lakes 3, 5, 9, 21, 22, 23, 30, 33, 36, and 38 where there are many 4-6-inch bluegill. Light lines, small jigs tipped with waxworms, worms or crickets have produced results in spring near brush and weed lines. Try fishing for redear sunfish in lakes 3, 4, 5, 6, 10, 11, 16, 20, 21, 23, 24, 27, 30, 31, 34, 35, 36, 37, and 38, and Fire Lake on Weldon Spring CA.

Rainbow trout will be available in lakes 3, 7, 21, 22, and 23 for excellent winter fishing, beginning in November. Lakes 7 and 21 host catch-and-release, artificial lures only fishing November through January and then allow harvest under statewide regulations. Lakes 3, 22 and 23 allow for harvest under statewide regulations immediately upon stocking. Though prepared baits continue to provide good action in trout harvest lakes, very light lines/tippets with 1/64-ounce black jigs or flies continue to be very productive.

Muskies will provide good fishing at Lake 35. Two muskies over 40 inches were captured during spring 2025 sampling efforts, with the largest at 40.8 inches. A master angler muskie was caught in November 2024, measuring 47 inches. Plastic swim baits, large crankbaits, and bucktail spinners have been most productive. Cedar tree brush piles will be added/replenished in 2025-2026 to help concentrate muskies.

Hybrid-Striped Bass have been stocked in lakes 7, 33, 34, 35, 36 and 38. The daily limit is 4 with a minimum length limit of 20 inches. Fish with cut bait or crankbaits, soft plastic jerk baits, spinner baits or casting spoons that resemble shad during dawn and dusk when fish are most active.
