<br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />'I <br />I <br /> <br />The NWS added ESP stream flow forecasting for the Cameo Gage during 1997, This capability <br />was utilized in 1998 to help coordinate reservoir operations, Additional improvements to the <br />extended forecast outlook were quite helpful and provide both improved and additional data for <br />use in the ESP modet <br /> <br />Finally, improved communications among all reservoir operators and water administration <br />officials would help. Towards this end, the state of Colorado will be implementing the water <br />administration tool as part ofCRDSS in 1998. This tool will help distribute real time <br />information concerning stream flows and reservoir operations to everyone as soon as it becomes <br />available. The tool may be ready for use in 1998, but likely not until the runoff season is over. <br /> <br />· Coordination with the Colorado Flood Task Force <br /> <br />The Colorado Flood Task Force continually evaluates the flood potential around the state during <br />the runoff season. The Task Force employees a private consultant (Henz-Kelly) to provide <br />extended weather outlooks and also identify areas of potential flood threats. Alternatively, <br />information on reservoir operations may useful to the Task Force. The exchange of information <br />between the coordinated reservoir operations group and the Flood Task Force should be <br />encouraged. In addition, the documentation of any flooding that may occur is of interest to both <br />groups and coordination of this effort could help stretch limited fmancial resources farther. <br /> <br />· Flood Warnings and "Pinch Points" on the River Affecting Coordinated Reservoir <br />Ooerations <br /> <br />Several stream gages on the river have elevation levels identified on them at which flood <br />warnings are issued. However, the State of Colorado and NWS do not always agree on what that <br />elevation should be. The Coordinated Reservoir Operations Group would like to see one set of <br />flood elevation levels identified for each stream gage upon which both the State of Colorado and <br />NWS agree. "Pinch Points" are points downstream from each reservoir where flooding will <br />occur first. These locations still need to be identified. <br /> <br />IX. Recommendations <br /> <br />The Coordination Committee has the following recommendations for future years: <br /> <br />A. Conduct coordinated reservoir operations again in 1999 pursuant to the schedule outlined <br />above. <br />B. Continue working with the NWS Colorado River Basin Forecast Center to improve peak <br />runoff fQrecasting. <br />C. Continue to coordinate with appropriate parties on river administration and accounting <br />issues. <br />D. Work with the state of Colorado and NWS to identify high flow levels and locations <br />potentially flooded or adversely affected by CROS. <br />E. Initiate work with the state of Colorado and NWS to resolve differing flood stage levels <br />or determinations at stream gages. <br /> <br />14 <br />
