International Field Year for the Great Lakes (IFYGL> 



The IFYGL is a program involving Federal, State, and Provincial agen- 

 cies, universities, and private industrial organizations in the United States 

 and Canada. Planning for this program has been in progress for several 

 years as a result of initiatives by the National Research Council of Canada 

 and by National Academy of Sciences of the United States, as part of the 

 International Hydrological Decade Program. NOAA became the U.S. lead 

 agency for IFYGL in October 1970. Other participating Federal agencies are 

 the Air Force Weather Service, Army Corps of Engineers, BSFW, Coast

 The New York State Department of Environmental Conservation is also in- 

 volved. International coordination is focused in a Joint (United States- 

 Canada) Management Team. 



The central objective of IFYGL is the development of a sound scientific 

 basis for water resource management on the Great Lakes as an aid in solv- 

 ing problems of water quality, water quantity, and other environmentally 

 sensitive operations. Lake Ontario and the Ontario Basin were selected as
