VARIATION IN GREAT LAKES LEVELS IN RELATION TO ENGINEERING PROBLEMS

W. E. McDonald

Abstract


Throughout the recorded history of the Great Lakes, the fluctuation in their water levels has created engineering problems generally unique in relation to coastal engineering. In periods of low water, demands are heard from navigation and power interests to raise the levels. In periods of high water appeals are made by shore property owners to lower the levels. Such conflicting interests present major engineering problems, the nature of which during a given period of time reflect the long-range upward and downward trend in lake levels due to natural phenomena.

Keywords
