ABSTRACT 



Surface currents of the waters of Saginaw Bay and 

 lower Lake Huron area were studied in the summer and 

 fall of 1956. Drift bottles were used in Saginaw Bay 

 and drift bottles together with the dynamic-height method 

 were used in Lake Huron. A total of 2,650 drift bottles 

 were released; 1,843 (69.5 percent) reply cards from the 

 recovered bottles were returned. 



Correlation appeared to be high in Saginaw Bay 

 between direction of surface currents that moved these 

 bottles and direction of winds. In Lake Huron this 

 correlation was less apparent, although the drift of 

 bottles was generally from west to east, seemingly under 

 the influence of the prevailing westerly winds of this 

 area.
