In many parts of the country, lakes are drawn down several feet in the Fall and Winter. This offers an excellent opportunity to see what you have, and what you could have, been fishing during the spring and summer months. Use a GPS or a video camera to record offshore structure you otherwise would have missed. You can often learn more about a lake in one trip during drawdown than you could in a whole season with standard electronics. Take care, though, as low water can lead to dangerous boating conditions.
