Rainfall over Lake Ontario and its basin will be measured more accurately than ever before by a special radar system which, together with a back-up rain-gage network, is now in full operation for the International Field Year for the Great Lakes (IFYGL).

U.S. radars located at Buffalo and Oswego, New York, will be tied in with a Canadian radar near Toronto (Woodbridge, Ontario) to cover the entire lake watershed. The Buffalo radar is operated by the National Weather Service of NOAA and has been specially instrumented to undertake this project. At the other end of the lake, a new radar has been erected about eight miles south of Oswego, and is operated by State University of New York at Oswego under contract to NOAA.
