Just trying to visualize the pattern. When you left Beaver, you moved to the North side near Rowena, which is closer to the dam, right? Were you working the points, or rolling up in the coves/slews?
I put the boat in about 65' of water in the mainlake cut, set my lines out and headed towards the point. All fish were caught as we were rounding the point onto the mainlake side. Kept the boat in 60' to 65' of water.
