<br />o Interstate Compact Policy, including evaluation of alternative <br />reservoir and river operating polices, determination of available <br />water for development, and maximization of Colorado's <br />apportionment. <br /> <br />o Water Resource Planning, including development and use of <br />a water resource planning model (i.e. new projects, water <br />exchanges, operating plans) and evaluation of impacts of <br />instream flow appropriations (e.g., endangered fish flow, <br />minimum flows). <br /> <br />o Water Rights Administration, including optimization of <br />water rights administration, on-line sharing of information <br />between water users, and administration of water rights within <br />compact allocations (i.e., alternative strategies of administration <br />which will enable the maximum use of available resource). <br /> <br />CRDSS DATA-CENTERED <br />CONCEPT <br /> <br />. . <br />f f <br />Models ~ Models <br />t t <br />. . <br /> <br /> <br />- <br /> <br />III. COLORADO RIVER DECISION SUPPORT <br />SYSTEM PROJECT <br /> <br />PROJECT ELEMENTS <br /> <br />Colorado River Decision Support System (CRDSS) project <br />elements have been organized into work tasks that, when completed, will <br />dovetail into a computer system which fully addresses the original goals. To <br />achieve an effective, user-oriented CRDSS, the development team will <br />focus on five critical elements. <br /> <br />1. DATABASE DEVELOPMENT <br />The data-centered architecture recommended for the CRDSS <br />makes the database a critical element of the system. The database will <br />include a relational database management system (RDBMS) and a <br />geographic information system (GIS). The RDBMS will be used to store <br />information suited to tabular formats (e.g., flow records, diversion structure <br />owner), and will interface with the DWR's HYDROBASE which is under <br />development by the DWR. The GIS will allow effIcient storage, retrieval, <br />analysis and display of spatial information (e.g. irrigated lands). Irrigated <br />acreage is being delineated on aerial photos by the USBR and field checked <br />by the DWR in a CRDSS related effort. <br /> <br />Q <br />Q <br />Q <br />Co) <br />-.J <br />Q <br /> <br />· Streamflow records <br />· Di version records <br />· Water rights <br />· Climate data <br />· User data <br /> <br />5 <br /> <br />
