Contents: This report presents the results of an investigation of the char- 
acteristics of winter current flow in Lake Huron. The investigative effort 
was undertaken during the winter of 1974-75 as a part of the International 
Joint Commission Upper Lakes Reference Study. The current surveys were 
accomplished through a cooperative effort of the Great Lakes Environmental] 
Research Laboratory (GLERL) of the National Oceanic and Atmospheric Admini- 
stration (NOAA), the Canada Center for Inland Waters (CCIW), and the US 
Environmental Protection Agency (EPA), Region V. The study reported here 
represents the first serious attempt to describe the winter circulation of 
Lake Huron. The data given for each selected time period of the survey 
gathered by 21 current meter moorings set by GLERI., 12 by CCIW's Canada Survey 
Ship Limos, and 9 by EPA's research vessel ROGER R. SIMMONS. The study gener- 
ated a series of 70 maps depicting the current roses for the various mooring 
sites (stations) at depths of 2 m, 15 m, 25 m, and 50 m above the bottom and 
wind roses for perimeter shoreline meteorological stations.
