I fish Lake Waco all the time. It’s an awesome white bass, hybrid and catfish lake. Not bad for largemouth. I don’t fish from the bank so don’t know of any spots to tell you but might try Airport park (Not Airport Beach Park) on the sandy beaches. I’ve caught white bass off those sandy spots before. Cast out as far as you can. If you see shad spawning on the beaches should be able to catch some whites.
