There're several larger waters that are easily reached from Auburn. Each has Bass/Sunnies in them. Try Rollins or Camp Far West Reservoirs, etc.

You probably already know this but if you encounter owners like Bill described and you want to gain access to ponds on those properties; visit the owner in person, spend some time asking for permission, assure that you'll not share permission with buddies or leave trash around the place. Sometimes that'll work.
