Here are some pics of limestone creek from 2017 when the water was at its lowest. You can zoom in and put pins on the stumps ,tops etc and save them. You can then convert them to gps files and put on a sd card and put them in your chart plotter,gps or depth finder. It is very accurate. I will include a u tube link that explains how to do this.You can zoom in on pics for better detail.
