Choteau Creek is good for Crappie located in the deeper brush piles within the creek.
The best bass fishing is located out in the grand river part of the lake fishing the brush piles with texas rigged stuff and Jigs. Dont let the current deter you, they seem to bite better when the river is flowing.
You can put out at Mazie Landing and access both of these locations. Choteau Bend is another great location to put out at.
Basically, the river end of the lake is the best IMO.
