Contour map · Crystal Lake, McHenry County, Illinois
Real surveys. Every line.
Each map is traced from the agency's own survey and says who made it. Drop a pin and the app tells you the depth under it, how deep the lake gets, and where the drop-offs are.
Three things on one screen
The map
Depth under your pin
