Costner Lake

Costner Lake sits in Calhoun County and is classified as a reservoir; I would pick one short area near the launch as the first place to get a feel for the opening section before leaving the first section behind. I would work one nearby area near the launch long enough to see whether the first idea has any life in it, because a first trip only needs to produce one useful clue.

Costner Lake Size, Maximum Depth and Volume

Costner Lake does not have a dependable set of published size and depth measurements, so I would check the first few places I can reach and avoid turning an estimate into a fact. The lack of exact measurements on Costner Lake makes one easy-to-read piece of water a sensible place to begin before making any assumptions about the rest of the lake.

Fishing This Water

Species information for Costner Lake is limited, so I would use a simple freshwater kit with a few soft plastics and live bait rather than commit to a species that may not be present. I would keep the second tackle change off the table on Costner Lake until I work through the nearby water while giving the first approach enough time to work.

A Practical Costner Lake Game Plan

For a first trip to Costner Lake, I would fish one sheltered section of bank long enough to judge the plan before moving, then rework depth before changing every bait without changing location, depth, and bait all at once. After Costner Lake gives me something repeatable around one short shoreline stretch, I would give that idea more time instead of immediately looking elsewhere, because a first trip does not need to accomplish more than that.
