Publication Date: January 1981 
Location: Eastern Lake Michigan, from Lakeside to 
Frankfort, Mich. 
Period of Coverage: August 1970 - December 1974 
Contents: Bluff recession and volumetric losses at 17 profile lines along the 
eastern shore of Lake Michigan were measured monthly from August 1970 to 
December 1974. This report discusses both the final period of study (October 
1973 to December 1974) and the combined data collected during the entire 
study, with primary emphasis on measurements of bluff recession. Section III 
discusses the study area and the primary processes which affect beach changes; 
Section IV discusses previous research; Sections V and VI present an analysis 
of the beach profile and sediment data; and Section VII summarizes the results 
and presents recommendations for future research. Beach and bluff changes, 
which were computed for the final period of study only, are discussed in 
Appendix A. Representative ground photos plus documentation of each bench- 
mark location and a short discussion of each profile line are given in 
Appendix B.
