Publication Date: March 1975 
Location: Lake Michigan 
Period of Coverage: 1900-1972 
Contents: This report describes the results of a study of Lake Michigan 
beginning-of-month water levels and monthly changes of storage. The study 
established that the number and distribution of water level gages in the 
presently existing gage network are adequate for the computation of beginning- 
of-month water levels. Computed beginning-of-month water levels and changes 
of storage for the period 1900-1972 are listed for use in scientific and 
planning studies.
