CRDSS <br />TASK MEMORANDUM 1.08-1 <br />Historical Database Data Requirements <br />1.0 ISSUE <br />Historic time series information is important in that it will drive the calibration efforts for both the <br />water rights planning model and the consumptive use model. <br />2.0 DISCUSSION/ANALYSIS <br />This document describes the required historical data, its possible sources, and its applicability to <br />certain models. The required historical data were determined by consulting both the water rights <br />planning and consumptive use modeling groups. <br />The database task leaders have met with the modeling task leaders to make sure the right data in the <br />correct format are in the various databases. The task leaders for Task 1.14, Consumptive Use Model <br />and Task 1.15, Water Rights Planning Model, have prepared task memoranda which document the <br />data needs for each of these tasks. This memorandum summarizes the historical data needed by both <br />of these tasks with emphasis on the Gunnison River basin. Also included are data types required by <br />other efforts to occur in later project years, as well as a description of where in the overall CRDSS <br />design they will reside. The data types are summarized in Table 1.08-1, and an anticipated <br />population schedule is found in Table 1.08-2 in Task 1.08 of the scope-of-work. <br />The historic database resides within and is part of the overall CRDSS relational database as <br />described in Appendix B. The database entities within the overall design that hold the historic data <br />are as follows: <br />daily_precip, daily_min_temp, daily_max_temp, daily_dew_temp, <br />daily_snow, daily_evap, daily_flow, solar_radiation, snotel, <br />monthly_temp, monthly_snow, monthly_flow, monthly_virgin_flow, <br />monthly_return_flow, monthly_evap, monthly_precip, wind_run, <br />annual_water_class, annual_amount, monthly_water_class, <br />monthly_amount, daily_water_class, daily_amount, <br />Irrig_time_series, res_meas. <br />Please refer to Appendix B, CRDSS Database Design, for more details. <br />Historic Diversions <br />Historic diversions describe the volumetric withdrawal rates associated with a private water right at a <br />specific structure. The most probable sources for diversion data are the State, Denver Water, U.S. <br />Bureau of Reclamation (USBR), water users, and USGS. Diversion data are used by the water rights <br />planning model during calibration. <br />Historic industrial, municipal, and thermal electric diversions describe the volumetric withdrawal <br />rates associated with an industrial, municipal, and thermal electric water right at a specific structure. <br />1 <br />A275 05.10.94 1.08-1 Greer, Ritsch <br />
