Same area as Dslayer, but head out towards the bird watching platforms off of the walkway. Grew up fishing for them with miniature marshmallows and nightcrawler combo and have caught some dandies. For hatcherry trout, I've found fishing right near the camp side of the spillway is a good spot. Charteuse anything is killer.
A guy can catch a few fish ice fishing in the winter and also near the clear creek inlet while sitting over decoys waiting for the ducks and geese to come in.
As far as rimrock goes, *cough cough* there's no fish in there. Night crawler off of the bottom if you want to keep entertained catching suckers and the occasional wild rainbow and cut throat. Did catch a really nice bull trout off of the point in 2012 on my kokanee setup.
