I live a few blocks from that creek. It's not a good fishing spot.
It's just a muddy creek and swells after a rain and gets really small during a drought. I believe it was named "Dead River" because it flows very slowly.
I've walked the banks of the Dead River from King George Road to Dead River Road casting lures the whole way and never got a hit.

I even put a minnow trap in there and only caught a few crayfish. It's a tough walk because the banks are swampy and covered with multiflora rose bushes that shred your clothes and scratch up your skin. That swamp probably gets unbearably buggy in the summer.
There is a small parking lot provided by the Nature Conservancy on Dead River Road just North of the powerlines so you can walk around that small parcel of land the Nature Conservancy bought.
I never bothered to walk the banks upstream from Dead River Road because every God damn tree on it has a 'No Trespassing' sign on it. Property tax records show the property is owned by the town, so I can't understand why every tree is triple-posted with 'No Trespassing' signs. Who cares if someone walks around in a town-owned swamp? My guess is it is put there by local townys or the hunting club that has a deer population control contract with the town. It's their private game preserve on public land.
It's too bad because I can see there is a pond off of Dead River Road where it goes over Route 78, but the side of the road there is plastered with 'No Trespassing' signs threatening arrest, prosecution, and eternal damnation if you dare to park there or enter the woods. Mind you this is town owned property.
