If you have a fish finder with hydrographic charts have you ever wondered what lakes are included in addition to the most popular lakes? Well C-Map 4D offers high quality charts for 148 Canadian Lakes.
Before I plan my trip to a new area I check my chart list to see if I have a hydrographic chart of the lake. In some cases that’s what determines which lake I fish. Knowing the exact locations of contour lines and depth is a major asset when you fish unfamiliar waters.
