Mardon Resort / Potholes Reservoir Fishing Report

The water level has dropped two feet this past week and is currently at 1030.95 feet. The water temps back in the dunes are reaching 83 degrees during the day with the main lake surface temps are in the low 80’s.
The walleye have scattered – but are eating! The Reservoir continues to drop at a quick pace – there are big fish as far as you can go up in the dunes, there are fish on the face of the dunes, and fish are holding around Goose Island. You will have to search shallow to deep to dial them in. Once you find one – work the area hard. The walleye are in transition – slowly moving out of the dunes as the Reservoir drops and the bait moves out. Best bet – troll #5 or #7 Flicker Shads in 8-15 feet of water on the face of the dunes and around Goose Island.
Several reports of big crappie being caught incidentally while fishing smaller crankbaits on the face of the dunes. The MarDon Dock fishing is coming on very strong with quality crappie, bluegill and perch. Largemouth bass in the 2-5-pound range have moved in under the dock. The dock fishing will continue to improve as the water level drops. Dock fishing is only available to registered guests staying at MarDon Resort.
The Channel Catfish and bullhead is as good as it gets! Fish around Goose Island, the face of the dunes, and up Crab Creek for Channel Cats up to 20 pounds!
The largemouth bass fishing excellent. Fish the dunes with SPRO Bronzeye Pop 60s, Rebel Pop-R’s and Zara Spooks for topwater action and Strike King square bill crankbaits in Bluegill or Perch patterns. There are good numbers of quality smallmouth bass in the dunes as well. Bass fishing along the face of the dam has been good this past week for both largemouth and smallmouth bass. Throw crankbaits, tubes, and 5” Kalin’s grubs for both.
