I have fished thenavasota that feeds into fort Parker more than the shallow barren lake itself. When you get there, find the ramp to the river located in the back right of the park. Then launch your kayak and head left in the river which heads back into the lake. In that section of the river I have had excellent results catching channel cat on a slip cork rig and cut bait fished along the bank and under overhang trees. Good luck
