Mardon Resort / Potholes Reservoir Fishing Report

The current water level on the Potholes Reservoir is 1044.63-feet – up slightly from last week. The water should continue to rise for the next several weeks to reach full pool of 1046.5 feet. The water temps back in the sand dunes are running in the mid-60’s. The water temps on the main Reservoir are in the upper 50’s to low 60’s.
The Largemouth and Smallmouth are beginning their spawning cycle. Most should bedded up by the next full moon which will occur on May 18th. Fish the sand dunes with ½ oz jigs and craw trailers, Swim Jigs, Chatter Baits, Punch Rigs and chartreuse Spinnerbaits. The water is clearing up in the Reservoir – making sight fishing a viable option. Throw a Wacky Rigged Senko or Berkley General to bedded fish. Fish in 1-10 feet of water along willow lines. There are Smallmouth back in the sand dunes and around the rocks around Goose Island. Fish Finesse jigs, Wacky Rigged Senkos, Crankbaits, and Swimbaits for the Smallmouth. Anglers have been doing well on Smallmouth on the face of the dam using crankbaits as well.
Walleye fishing is improving. The walleye have finished spawning and have moved down from their spawning areas to the weeds back in the dunes. Fish the dunes with a swim jig or swimbait along the weed lines in 2-6 feet – or fish the channels with Smile Blades/Super Death Hooks/2 oz bottom walker and ½ a crawler in 8-15 feet. Troll from .8-1.2 miles per hour. A few walleyes are being caught on #5 & #7 Flicker Shads and Rapala Shad Raps.
Trout are being caught off Medicare Beach both from shore and by boat. Bank fisherman are using Power Bait, worms and marshmallows, a 12-18” leader, and a 1/8-1/4 oz. egg sinker above the swivel. Boat anglers are trolling Needlefish spoons, #7 Flicker Shads and Shad Raps. Trout fishing in the Seep Lake has been very good this past week. Top Lakes have been the Hamptons, Warden Lake, Corral Lake and the Widgeon – Pillar Chain. Top Baits have been Worms and marshmallows, Berkley Powerbait, Rooster Tails, and Berkley Mouse Tails.
The crappie and bluegill are beginning to show up at the MarDon Resort dock. Several good catches of 10-12-inch crappies are coming in. Fish trout Magnets, flies, VMC Wingding jigs and Berkley Gulp Alive Minnows on a 1/32 oz. jig head. Only registered guests of MarDon Resort are permitted to fish off the dock. By boat, head back in the dunes towards the Job Corps dike and fish the willows for bluegill and crappie using the same baits mentioned above.
The fishing is improving daily – call the MarDon Tackle Store for the latest fishing info at 509-346-2651.
