available on a daily time step in HydroBase; therefore filled monthly aggregate data values <br />under Task 3 (LRE, 2007a) were used. A daily average of each aggregate monthly diversion <br />was calculated and used for the daily gain/loss analysis. The aggregate diversion po>11ts and <br />their locations are listed in Appendix A. <br />1.2.4 Reservoir Release Data <br />Reservoir releases were also included >lz fl1e gain/loss analysis. Jackson Lake and Prewitt <br />Reservoir outlets both release directly into the Sout11 Platte River. Reservoir releases are not <br />recorded on a regular basis and daily data was unavailable, therefore reservoir releases <br />previously identified under Task 5 of the SPDSS (LRE, 2006) were utilized >11 the gain/loss <br />calculations. Reservoir release data was previously est>lnated on a mont111y basis by t11e SPDSS <br />Water Balance contractor. For this level of analysis, the monthly release data was used to <br />estimate the daily reservoir releases by dividing the monthly data by the number of days in the <br />particular month. This process was deternuned to be adequate and consistent with the SPDSS <br />Water Balance contractor. <br />1.2.5 Municipal Discharge Data <br />Three industrial and 14 municipal entities directly discharge into the South Platte River, Cherry <br />Creek, or the Cache la Poudre River reaches included in this evaluation and are listed in Table 4. <br />These entities are included in this analysis because $Zey are classified as major dischargers by <br />the Environmental Protection Agency (EPA). The major discharges are defined by the EPA <br />based on a scoring of several categories including: Toxic Pollutant Potential, Flow/Stream <br />Volume, Conventional Pollutants, Public Health Impact, Water Quality Factors and Proximity <br />to Coastal Waters. Additional muzor dischargers were also identified but were not included uz <br />the gain/loss calculations due to the small amount of permitted discharge flow. Dischargers <br />and discharge point locations are identified for eac11 reach define in Table 1 in Appendix A. <br />Table 4 -Major Dischargers Within the Gain/Loss Study Area <br />Brighton <br />Brush <br />Littleton-Englewood <br />Commerce Cit <br />Fort Lu ton <br />Fort Moran <br />Greeley <br />Sterling <br />Fort Collins <br />Evans <br />Wiizdsor <br />Glendale <br />Stoneaate <br />Public Service Compare of Colorado Arapahoe Station <br />Public Service Company of Colorado Cherokee Station <br />Eastman Kodak Compare <br />Metro Wastewater Reclamation District <br />SPDSS Phase 4 Task 46 Technical Memorandum -Final <br />0~4i 10i0~ <br />
