I second Elkhorn Creek in Georgetown. I haven't fished for bluegill there but have caught a boatload fishing for bass. The pool downtown across from Cardome has quite a bit of bank on both sides of the creek. I think the track side of the creek my be owned by the subdivion that backs up to it but I have run on the track with no one saying anything.

I don't know your budget but you can rent johnboats at Stoner Creek and Guist Creek Lake. If you had a buddy to chip in, I don't think it would cost much. Steve
