·         At 7 a.m. on Friday, Sept. 13, the discharge rate will decrease from approximately 1,104 cubic metres per second (39,000 cubic feet per second) to about  963 cubic metres per second (35,000 cubic feet per second).

·         At 8 a.m. on Friday, Sept. 13, the discharge rate will decrease from approximately 963 cubic metres per second (35,000 cubic feet per second) to about  850 cubic metres per second (30,000 cubic feet per second).

·         At 7 a.m. on Saturday, Sept. 14, the discharge rate will decrease from approximately 850 cubic metres per second (30,000 cubic feet per second) to about 708 cubic metres per second (25,000 cubic feet per second).
