I've made two trips to Sibley this year and caught nice fish on both trips. Drifting with Shiners in April caught around 30 and pulling cranks in July and caught 17.
Sibley has some nice fish on it and I have not fished the other locations. You will need to buy a lake permit to fish Sibley and it cost 10.00, unless your are 60 or older. Permit is good for the year and can be purchased from store right across from boat ramp.
