Its about time to start dropping structure in again at our ranch, got a few questions. I've had what I will call spectacular success so far dropping piles somewhat randomly, or dropping it on existing structure to enhance it/make it bigger. This time I'd like to target better locations. So here is my situation. Three 10 surface acre lakes, maximum depth being 15-20 FOW. Earth dams that run along one edge on each. Here is the kicker, I don't use electronics out there typically so I put the structure where I can find it again based off landmarks on the bank. This also keeps me from knowing how the middle of the lakes look at the current moment, so no dumping randomly otherwise I won't find them and may just be putting them out on a flat. I've put limited structure along the dams so far and both have produced crappie but I dropped them on the slope and not at the bottom. I'm thinking of doing this again as I know there is a drop off of about 12-15 feet along most of the dams. Do y'all think this is a sound idea to try and drop the structure at the base of the dam?

Thanks in advance, Rex
