Starting in 2016 we began the process of mapping the system with our sonar system. Every year we are able to map around 2-3000 acres. Another 20 years and we may have it done, but it’s a start! This map appears that everywhere is 12 feet deep, however if you zoom in it will show great detail using the + and – on the bottom left of the map. Enjoy!
