"Knowledge of the hydrology of the Great Lakes and the reliability of its component phases is basic to the management of the lakes as a water resource. Although the lakes are a unique system in terms of their area and relation to each other, they have only received intermittent attention from hydrologists during the last fifty years. As a result, today there is no complete documentation of the various components of their hydrology. It would be presumptuous to attempt a detailed description in one paper of the hydrology of an area which occupies about one-third of a million square miles of central North America. What can be done, however, is to provide some impressions of the relationships of water to land and atmosphere of the basin. This is done through a discussion of the relationships of component phases of the hydrology of the land and lake areas"--Introd., p. 1. Hydrology Great Lakes (North America) Canada.
