There's places on that creek I simply don't fish anymore, because of the things and people I've encountered out there. There was a huge homeless camp near the Roderick Rd. bridge, just downstream of it. by the pull out. I used to be fine parking at the pull out and walking through the creek to the woods - but that camp kept getting worse - there were needles and disgusting items abounding. I just started getting creeped out more and more there and stopped fishing there before something happened to me or my car. I've parked up by the Roderick Rd bridge, and been OK. I've gotten some interesting looks by landowners on the west side of the creek, but no one ever said or did anything.
I mostly stick to the water up by the hwy 8 & 6 merge, walk down across from Dorman's Pond and fish up or downstream for 1/4 mile either direction, then switch and fish my way back the other way just as far. If you fish methodically, it can take half a day to work that half mile of water. Good fly or spinner water up there. The up-river public water, like you mentioned, gets awful skinny in the summer.
