Latest fishing report

DWR report dated Sept. 17, 202654 days old, seasonal outlook

Fall outlook: cooling water draws trout toward the shallows, while warmwater fish (largemouth bass and bluegill here) move deeper. For rainbow trout, shore anglers can fish a worm or dough bait on the bottom in the shallows, and boaters can troll crankbaits, pop gear with a worm, or a dodger paired with a squid, at any depth from just below the surface to 40 feet down. Largemouth bass eat mainly yellow perch and young bluegill, so cast spinnerbaits, crankbaits, twist tail grubs or tube jigs straight out from shore. For bluegill and other sunfish, fish a worm beneath a bobber on a No. 8 or No. 10 hook around sunken brush or water plants. For yellow perch, work sandy shorelines with a worm fished beneath a bobber or dropped to the bottom, or, from a boat, look for schools in 6 to 30 feet of water and jig a worm-tipped jig or spoon straight down once you find them.
