Based on my experience crappie lakes go in cycles. My favorite local crappie lake will have great years and some down years. One year the lake was 5ft high during the spawn and you could not find them because there was thousands of acres of new spawning spots that you could not access by boat. The lake exploded with crappie three years after that spawn. The same exact lake experience a severe drought back 2012 and the lake was 8ft low. They were easy to catch but it ruined the spawn and fishing was horrible for a few years due to the bad spawn. Crappie are prolific breeders so it is pretty hard to fish them out of a decent size lake even with Livescope. You will be shocked at how many times I have marked fish and they will not touch a jig or a minnow. Like stated I am not a screen watcher. Once I find a school a fish I marked the distance and depth and start casting/pitching to them. I don't have to be screen watcher to use livescope.
