Bureau of Reclamation <br />ColoradoRiv~r Basin Salinity Control Program <br />Accomplishments for fiscal year 1996 <br /> <br />Colorado River Simulation System Support <br /> <br />Colorado River Simulation System (CRSS) is used extensively by Reclamation to forecast salinity <br />conditions and evaluate compliance with the water quality (salinity) standards. To do this,accurate <br />water use data is needed as a base for these predictions. In cooperation with the Upper Basin <br />States, Reclamation is creating a GIS database of irrigated field boundaries and crop types to refine <br />current water use estimates in the entire basin. In 1996, Reclamation completed its GIS database' <br />and has begun to produce water use estimates for the Upper Basin thrn 1990. In 1997, <br />Reclamation plans to bring the analysis up thrn 1995 and then provide annual updates. <br /> <br />CRSS Replacement <br /> <br />Reclamation has retired its CYBER computer in Denver, the old computer platform for CRSS. <br />CRSS has been replaced by a model (P-CRSS) which is being developed jointly between the TV A <br />and Reclamation. A functional version of the model has been completed and successfully tested <br />against output produced by CRSS. Reclamation will continue to develop the capabilities of the <br />new model. <br /> <br />Update to Economic Impacts Model <br /> <br />Reclamation has begun a major update of its economic impact model. Reclamation has converted <br />the model to a Lotus spreadsheet format. This has eliminated severallogisticaI problems in using . <br />the model and allows easy access to the data and output. The next phase in updating the model will <br />be to update the crop types and acreages in the model. This work is currently underway in <br />Reclamation's Technical Service Center. Future work will update the M&I impacts section of the <br />model. Wastewater reuse was not addressed in the current model. This issu.e will beevaluated in <br />1997. . <br /> <br />Glenwood-Dotsero Springs Unit, Colorado <br /> <br />Under a cooperative agreement with Reclamation, private developers investigated the feasibility of <br />privatizing salinity control of the saline springs around Glenwood Springs, Colorado. The <br />developers have not been able to meet the cost-effectiveness parameters detailed in the cooperative' <br />agreement. The cooperative agreement expired June 1, 1996. <br /> <br />Price-San Rafael Rivers Unit, Utah <br /> <br />Three cost-effective proposals were received from waternsers in the Price-San Rafael Rivers Unit in <br />response to Reclamation's request for proposals under P.L. 104-20. Negotiations are underway to <br />execute construction cooperative agreements with the three proponents. <br /> <br />19 <br /> <br />
