ABSTRACT 



Surface cuirents were investigated in central and southern 

 Lake Michigan in 1954, and in central and northern Lake Michigan 

 in 1955. Drift bottles, drift envelopes, and plastic tubes were 

 released in 1954, whereas drift bottles only were used in 1955. 



Currents were highly variable in both years and in all areas of 

 Lake Michigan. The general direction of drift was from west to 

 east; cuirents were predominately north-bound along the eastern shore. 

 No jvevailing current was detected along the western shore.
