Table 1. Release Guidelines for the Environmental Account for the Water Year 2001 (The two ulse./low eriods are shaded) <br />March 23 - May 10* 2,400 whooping crane, fish community, piping Medium Projected flows indicate that average and/or <br /> 2,400 plover, least tern, sandhill crane dry targets will not be met. A medium priority <br /> 1,700 will be given to maintaining adequate base <br /> flows during this period for spring migrarion. <br /> See comments for Feb./Mar Period. <br />May 1- June 30' 10-yeaz ninning The principal affected resources are river and High See comments for Feb. 16 - March 15 Period. <br /> average of 30-day ripatian wetland processes such as <br /> exceedance for 3,400 maintaining channel morphology; sediment <br /> cfs, and 5-day supply; sandbar formation; nutrient cycling; <br /> exceedance of 8,300- backwater habitats; groundwater recharge; <br /> 10,500 cfs and behavioral cues for fish spawning; <br /> reproduction, movement, and redistdbution. <br />May 11 - Sept 15* 1,200 fish community, least tern Medium Projections indicate that shortages to dry <br /> 1,200 targets will occur during September. <br /> 800 Historically, fish kills have occurred during this <br /> period which could adversely affect fish <br /> community health and jeopardize tem food <br /> sources. Flow condirions, irrigarion demand, <br /> and temperatures will be closely monitored <br /> during this period to insure adequate flows are <br /> maintained. <br />Sept 16 - Sept 30 1,000 fish community Low Projecrions indicate shortages to dry flow <br /> 1,000 targets during this period. Because lower <br /> 600 ambient temperatures and decreasing irrigation <br /> demand during this time period typically result <br /> in improved river conditions, though not <br /> guaranteed, a lower priority is given. <br /> However, flow conditions, irrigarion demand, <br /> and temperatures will continue to be closely <br /> monitored. <br />Water Year 2001 EA AOP 13 January 3, 2001
