If water temperatures increase substantially because of decreased flows during this period, fish community health and tem food sources could become jeopardized. Flow conditions, irrigation demand, and temperatures will be closely monitored during this period to insure adequate flows are maintained. Sept 16 - Sept 30 1,000 fish community Low Projections indicate shortages to average and 1,000 dry flow targets during this period. As lower 600 ambient temperatures and decreasing irrigation demand during this time period typically result in improved river conditions for the fish community, though not guaranteed, a lower priority is given. However, flow conditions, irrigation demand, and temperatures will continue to be closely monitored. Water Year 2002 EA AOP 11 January 7, 2002
