- If no related information is available, outlet release capacities should be estimated based <br />on the maximum change of historical end-of--month contents (actual or calculated), based <br />on a constant release rate during the month. <br />RESULTS <br />Storage Water Rights <br />Absolute storage water right data available from HydroBase is considered complete. A reservoir <br />commands file will be created in StateDMI during the surface water modeling effort to access <br />storage water right information included in HydroBase for the development of a StateMod <br />reservoir rights file (*.rer). The command file will initially include only key reservoirs. It will be <br />revised to include the individual facilities within reservoir systems once the ResSysQ command <br />is coded in StateDMI to address reservoir systems. <br />Historical End-of-Month Contents <br />Historical data included in HydroBase were used as the first source of information for the 101 <br />reservoirs, comprising 51 key reservoirs and reservoir systems in the SPDSS study area. <br />Commands files were created in TSTooI to: <br />• Access available content data from HydroBase, <br />• Fill missing data for key reservoirs with SEO Records or user records summarized in <br />StateMod format files (*.stm), <br />• Linearly interpolate to fill any remaining missing periods of up to two months, <br />• Fill missing data with wet-, dry-, or average-year monthly averages based on the fillpattern <br />file (*.pat) created in Task 80 using the following key stream gages identified in Task 2: <br />- Water District 1: 06714000, South Platte River near Kersey <br />- Water District 2: 06720500: South Platte River at Henderson <br />- Water District 3: 06752000, Cache la Poudre at mouth near Ft. Collins <br />- Water District 4: 06738000, Big Thompson River at Mouth of Canyon near Drake <br />- Water District 5: 06724000, St. Vrain Creek at Lyons <br />- Water District 6: 06724000, St. Vrain Creek at Lyons <br />- Water District 7: no missing reservoir data filled in Water District 7 <br />- Water District 8: 06714000, South Platte River at Denver <br />- Water District 9: 06710500, Bear Creek at Morrison <br />- Water District 23: 0669500, South Platte River above 11-Mile Canyon Reservoir, near <br />Hartsel <br />- Water District 47: no missing reservoir data filled in Water District 47 <br />- Water District 64: 06764000, South Platte River at Julesburg <br />- Water District 80: no missing reservoir data filled in Water District 80 <br />Missing content data for off-channel reservoirs in reservoir systems were filled in Task 80 <br />based on the ratio of total storage capacities and complete end-of--month contents for other <br />off-channel reservoirs in the same reservoir system, as described previously. <br />Area-Capacity Curves <br />A reservoir commands file will be created in StateDMI during the surface water modeling effort <br />to incorporate area-capacity curves provided by owners/operators and Water Commissioners and <br />Page 4 of 11 <br />
