5. Reclamation will work with the State's Water Quality Control Division and other interested <br />parties to compare their water quality data with Reclamation's operational data to determine if <br />there is a correlation between selenium concentrations (on the Arkansas River from Pueblo <br />Reservoir to the Rocky Ford headgate) and changing hydrology as a result of temporary excess <br />capacity contract operations for the years 2006 through 2010. <br />6. Temporary excess capacity contract operations shall not cause flows on the Arkansas River as <br />measured at the Avondale gage to fall below 86 cfs. <br />7. In support of the Upper Arkansas River Flow Program (Flow Program), Contractors may not <br />exchange water from Pueblo Reservoir to upstream locations as against releases made by <br />Reclamation in support of the Flow Program, or make any exchanges from Pueblo Reservoir <br />which would require Reclamation to release additional water to meet the objectives of the Flow <br />Program. Based on past recommendations provided by the Colorado Department of Natural <br />Resources, recommendations typically involve: <br />® Maintenance of a minimum year- round flow for fishery purposes <br />(250 cfs) <br />Maintenance of a winter egg incubation flow <br />(November 15 - April 1, 250 -400 cfs) <br />Maintenance of a minimum hatching flow <br />(April - May 15,250 cfs) <br />Y Augmentation of rafting flows <br />(July - August 15, 700 cfs) <br />Avoidance of fluctuation greater than 10 -15 percent of total flows <br />C Reduction of flows for trout feeding <br />(September - October, 250 cfs) <br />8. Reclamation will not execute contract exchanges until the Natural Resource Conservation <br />Service makes its annual May Is` water supply forecast, and Reclamation determines whether or <br />not contract exchanges will affect its ability to operate in accordance with the Flow Program <br />recommendations, or impair the ability of Fremont Sanitation District Wastewater Treatment <br />Plant or the Salida Treatment Plant to meet their discharge permit requirements. <br />9. Reclamation will limit temporary excess capacity contract operations that have the potential <br />to affect the Arkansas River below Pueblo Reservoir when flows are :5 500 cfs and> 50 cfs to a <br />decrease of no more than 50 percent of the average daily flow as measured by adding the flow at <br />the above Pueblo gage to fish hatchery return flows. <br />10. Reclamation will limit temporary excess capacity contract operations that have the potential <br />to affect the Arkansas River below Pueblo Reservoir when flows are :S 50 cfs, as measured by <br />adding the flow at the above Pueblo gage to fish hatchery return flows. <br />I:W <br />
