Do you check the AR fishing reports? Here's some striper info from the report, it at least gives you some starting points:
Bailey’s Beaver Lake Guide Service (479-366-8664) said the lake is fairly clear, especially from Point 3 to the dam. Fish early because surface temperatures are high. Stripers are good on live shad fished on free lines and balloons from 2 to 20 feet deep, above the thermocline. On the mid- and lower sections, check out Point 1 (The island is still holding some fish, but most are going deeper with the rising temperatures.), Indian creek (Good fishing), Lost Bridge South (Good fishing), Lost Bridge North (Excellent fishing), Big Clifty arm (Good fishing), Point 3 (Good striper activity in front of Starky Marina) and Point 5 (This area is a hot spot and fish are being taken under lights.). Try Horseshoe Bend in the upper section where walleye are being caught near the hatchery pond. Most walleye are about 10 to 20 feet deep near Point 5, Point 3 and Point 1. Flat line troll over shallow bars with Rapala Tail Dancers, Shad Raps, Reef Runners, or Ripstiks in natural blue or black back combos. Jigging spoons around brush and rock piles are also producing. Put your Dipsy Divers to work above the thermocline with a Rapala in tow.
