TABLE 1 <br />CRDSS USERS AND JOBS <br />CRDSS Jobs and Uses: <br />R egulator y Studies an d WaterDailyInterstat e <br />L evels of CRDSS User s: ControlsPlansServicesOperation s Issues <br />Decision Makers / <br />Administrators <br />Analysts/Engineers <br />Operations Support <br />External users include those who are regulated by the state agencies, and who in turn plan and manage <br />the water resources under their jurisdiction. Denver Water, the Colorado River Water Conservation <br />District, and the Northern Colorado Water Conservancy District are notable in this regard. Within these <br />agencies? staff there is the full spectrum of user levels ranging from operations support, analysts and <br />engineers who do assessments and plans, and decision makers/administrators who oversee the others. <br />It was difficult to clearly define the exact job activities of some of the staff categories. For example, the <br />analyst/engineer for the CWCB may be requested to prepare a study of some water rights issue and <br />submit conclusions for consideration by the Board. The nature of such work cannot be characterized in a <br />strict linear manner; it requires exploration and creativity to address the problem. And no two people <br />may do it the same way. Thus, the CRDSS design should allow for such exploration in a flexible <br />manner. Operations staff, on the hand, usually have very clear ideas about how their workflow would <br />proceed, and for these people the use of the CRDSS could be defined in a more step-by-step manner. <br />Information Needs and Workflow Review <br />Information Needs <br />User needs responses divided along job functions. Appendix C presents a summary tabulation of the <br />respondents? information needs. Administrators want information for planning and making management <br />decisions. Operators need more accurate and timely data to conduct operations. Operations staff were <br />more detailed in defining their needs, and listed content as well as format needs. Content needs ranged <br />from kinds of data needed such as water rights, consumptive use (CU), diversions, reservoir levels, <br />irrigated lands, and crops. Operations staff indicated very strong demand for real-time data and flow <br />forecasting tools, including keeping track of the ?color? or water right attributes of water in the river at <br />any time and point. There was an expressed need to keep track of flows in the river at any location, not <br />just at gage points. <br />Analysts indicated a strong need for the consumptive use modeling and database capabilities of the <br />CRDSS. This need bridged the job functions from regulatory control, planning studies, operations, water <br />services, and interstate issues.
