Hey there...AEKDB.....(Kappa Sig from Epsilon Mu in Tulsa -- though it has been a while.) 
 
I would recommend going to Marval outside of Gore.  There is several fishing locations, bathroom facilities and camp sites or cabins depending on what you prefer.

Have fun.  The hard thing will be to plan on a time when the river is down, if it is up it is almost unfishable.  There is information on this forum, as well as John From Marval can try to help - but you literally fine out 8 hours before if the water will be on, though they do post the water releases for the whole weekend on Friday after 5pm. 
 
hope this helps, 
Scott
