nonrecording gage at same site and datum.
REMARKS.--Records good except for period of estimated discharge, which are fair. Flow is regulated by reservoirs in Canada

1992). Total reservoir capacity is about 490,000 acre-ft. Some diversions for irrigation and municipal supply.
COOPERATION.--This station is one of the international gaging stations maintained by the United States under agreement with
