Fishing report for the week of 06/09/2025
Walleye fishing is really getting good between mid-reservoir and the south end. Trolling bottom bouncers with worm harnesses in 12-15 feet of water between Duck Creek and Pond 1 has been the most productive. White Earth to Round Top has produced great results as well with some anglers using jigs. Rainbows continue to be caught on the north end and around White Earth while trolling crankbaits, spoons or cowbells. Rainbows are also being caught while fishing for walleye. Shore fishing has produced both rainbows and walleyes on worms or jigs with a worm around Broadwater Bay and north of the Silos. The carp spawn is in full swing with both bow fishing and hook and line providing great action.
