Much of what happens beneath the surface is unseen by most users of a lake. Underwater videos provide a unique window into that world. The author has taken and analyzed hundreds of hours of underwater videos of this lake over the past 30 years. This, plus his background as a fish biologist, has allowed him to paint a vivid picture of the complex seasonal rhythms of life that take place in any north country lake. Contains 180 color illustrations.

Bruce Carlson combines almost 70 years of observations, along with his training as a scientist, to provide a unique perspective on the natural history of an iconic north-central Minnesota lake. From ice-out in the spring, through the open water season, to the next winter, this profusely illustrated book provides a vivid picture of the seasonal changes in a lake. The account of these changes includes not only observations of what can be seen above the surface and on the land surrounding the lake, but also almost 75 underwater videos (in the electronic version that accompanies the printed book, sold separately) that depict in stunning detail the underwater landscape of a glacial lake and its inhabitants.
