I just got back from a two day, my partner went up a week ago and slayed them in the outside reeds pitching jigs on the north end. We go out the next week low and behold the fish are gone. The first day of the tourney everyone that fished inside caught good fish, we moved in the second day and caught fish all day but to little to late.
The winner had a two day total of 40 something pounds. This was Friday and Saturday. The big fish moved inside the first island shallow and were hitting toads and flapping shads.
One mistake we made was sticking to our pattern the first day too long, I would pitch the reeds and if their in there you'll get bit right away, jump around to the outside points don't spend a lot of time on one patch, if you cant find fish move shallow and start throwing frogs,Flukes,or whatever you like in shallow water.
Theres also some nice fish in the pads that are east of Istapoka Park, if you come out of the park channel and turn east go to the end (Northeast side of the lake) you'll see some pad fields, second place came out there, we caught a lot of fish there ourselves the second day but found it too late, we nailed a 4lber, Flapping shads through the pads, its hard fishing you'll lose some fish, so use a broom stick and braid.
Hope this helps good luck.
