Table 2. Release Priorities for the Environmental Account for the Water Year 2007 (The nvo pulse fiow periods are shaded.) <br />Carry-Over N/A Use of EA water for beneficial puiposes as Low/Medium Considering EA volume, pulse flow augmentation <br /> described for other time periods. needs, and the Platte River Program beginning in <br /> January 2007, retaining EA water for carry-over <br /> purposes is given a low/medium priority. As the water <br /> year progresses, hydrologic conditions, EA volume, <br /> reservoir levels, and species/habitat needs will be <br /> closely monitored to determine how much water can or <br /> should be retained in Lake McConaughy for carry-over <br /> purposes. <br />* During May 1- June 30, high priority pulse flow requirements overlie the flows for species-specific physical aquatic habitat. May and June recovery flow targets are <br />designed to capture natural variability: a 10-year running average with a 30-consecutive-day exceedance of 3,400 cfs, and a 5-consecutive-day peak flow exceedance of 8,300- <br />10,500 cfs. Within this broad goal there are further recommendations that certain flow levels be achieved with specific frequencies (see Bowman and Carlson et al. 1994). <br />* The 5-day peak flow with ramped rate of rise and decline may occur in either February-March or May-June. <br />Water Year 2007 EA AOP 11 January 19, 2007
