some two-point curves for reservoir systems in the development of a StateMod reservoir <br />structure file (*.res). <br />Monthly Net Evaporation Rates <br />Net evaporation rates specific to key reservoir locations in the SPDSS study area were developed <br />based on the net evaporation rates developed for each Water District based on locations above or <br />below 6,500-feet in elevation (see Task 53.3 memorandum). A reservoir commands file will be <br />created in StateDMI during the surface water modeling effort for the development of a StateMod <br />net evaporation file (*.eva). <br />Reservoir Account Ownership and Storage Capacity <br />Information gathered related to reservoir accounts and their operations are included in the 28 <br />memoranda developed for SPDSS Task 5. Information provided by owners/operators regarding <br />account ownership is summarized in Table 2. Without this information, storage facilities will be <br />assigned one owner and one account. Operations associated with reservoir accounts will be <br />addressed during the surface water modeling effort in a StateMod operation rights file (*.opr). <br />Active storage capacity data provided by owners/operators of facilities will be used, if available, <br />followed by information contained in HydroBase regarding total storage capacity and dead <br />storage in the development of a StateMod reservoir structure file (*.res). Without information <br />from these or other sources, the active storage capacity will be set to maximum historical end-of- <br />month contents with dead storage equal to zero. <br />Historical end-of--month content data have been reviewed for most of the key storage facilities to <br />identify any records greater than the available storage capacity. These reviews identified some <br />errant end-of--month contents data that have been revised, as appropriate, by the Division 1 <br />Engineer's office and included in updates to the HydroBase database. <br />Maximum Outlet Release Capacity <br />Maximum outlet release capacity is used by StateMod as a potential limit in the simulation of <br />reservoir operations. Information provided by owners/operators and Water Commissioners will <br />be used in the development of the StateMod reservoir station file (*.res) commands file for the <br />key reservoirs in the SPDSS study area. Missing data will be filled with information contained in <br />HydroBase; otherwise, maximum outlet release capacity for key reservoirs will be based on a <br />review of the complete end-of--month contents data developed in Task 80. The same <br />methodology should be used for the off-channel reservoirs. <br />RECOMMENDATIONS <br />The reservoir structure information for key reservoirs gathered for this effort will be used to <br />develop the reservoir structure file (*.res) and reservoir rights file (*.rer). The available <br />information, summarized in the memo tables should be considered works in progress with <br />additional information incorporated as it becomes available. The *.stm files developed for the <br />key reservoirs will provide the basis for the eventual development of the StateMod historical <br />end-of--month contents file (*.eom) and reservoir targets file (*.tar). <br />Page 5 of 11 <br />
