Potholes Reservoir / Mardon Resort Fishing Report

The current water level on the Potholes Reservoir is 1029.55 feet – down 1.20 feet from one week ago. The water temps in the sand dunes and on the main Reservoir are in the upper 70s to low 80s. With the water level as low as it is – use extreme caution while boating between Goose Island and the face of the dam and the face of the sand dunes.
The bass fishing continues to be excellent! The water continues to drop – pulling baitfish and the bass to the face of the dunes and onto the habitat boxes and humps. Fish the sand dunes and Crab Creek with 3/8th oz. swim jigs, Senkos, Strike King KVD 2.5 Square Bill crankbaits, and SPRO frogs. As the water continues to drop – the outer dunes and the face of the dunes will continue to improve. Reports of bigger bass are coming in – being caught on the face of the sand dunes in 15-25 feet of water. The Smallmouth bass are being found on the face of the dam and on the rock piles around Goose Island – as well as in the sand dunes. Fish Booyah finesse jigs, Wacky Rigged Senkos, Crankbaits, Tubes and DS Minnows for the Smallmouth.
A few more walleye are being caught. Like the bass fishing – as the water drops – both baitfish and the walleye will move out of the dunes to the face and onto the humps. Fish face of the sand dunes in front of the West Arm and Crab Creek in 6-20 feet of water. Fish a Slow Death Hook and a 2 oz. bottom walker and ½ a crawler in 8-15 feet. Troll from .8-1.2 miles per hour. Troll a #5 Flicker Shad or Rapala Shad Rap in the channels and next to the weed beds at 1.5 – 2.5 miles per hour.
Several reports of good trout fishing came in this week from Medicare Beach to the Mouth of Crab Creek and in front of the State Park. Troll Gibbs Wee G Spoons, Wicked Lures Trout Killers, Needlefish spoons, #7 Flicker Shads and Shad Raps at 2.5 -3.0 mph. Set the drag light as the average trout is 2-5 pounds and can break the line on the initial strike.
The Channel Cat and Bullhead fishing continues to be extremely productive this week. Use Catfish Magic Bait, Berkley Catfish Nuggets, and worms on the bottom for both. Fish up Lind Coulee, the mouth of Frenchman’s Wasteway and in the sand dunes for Channel Cats and Bullhead.
Big Bluegill and big crappie are being caught on the face of the dunes and in the mouth of Crab Creek. Several reports of good crappie fishing in Lind Coulee have come in as well. Troll #5 Flicker Shads to locate schools or use your electronics to find the schools and drop Bobby Garland Baby Shads and Trout Magnets to the fish. Perch are being caught in the mouth of Crab Creek and on the humps in front of the exposed dunes.
