In St. Martin Parish, Warner Lake is listed as a lake, so the first move is to fish one reachable area before widening the search. I would begin around one easy-to-read area near the launch instead of trying to cover the whole water, because that approach makes the second trip easier to plan.
Warner Lake Size, Maximum Depth and Volume
A dependable standalone acreage, maximum depth, and storage figure is not published for Warner Lake, so the safer move is to leave the missing number alone until a reliable source turns up, and I would rather leave the missing number alone until a reliable source turns up. I would spend more time looking at the immediate area for yourself, and I would leave the missing numbers alone instead of borrowing them from another lake.
Fishing This Water
The fishery at Warner Lake is lightly documented, and that gives me a reason to carry simple freshwater gear until the fishery is clearer, and that gives me a reason to wait for actual catches before specializing the tackle. I would keep things simple with a light spinning setup with worms, small jigs, and one moving bait, because if something starts biting, the rest of the trip can be built around that clue.
A Practical Warner Lake Game Plan
My first plan for Warner Lake would be to fish one familiar-looking shoreline stretch deliberately and make changes only when the results justify them; a slow start is a reason to make one thoughtful change rather than rebuild the entire tackle plan.
