Memorandum to CWCB Page 2 • Discussion The Satellite-linked Monitoring System (SMS) has been operating since 1985, starting with 82 linked gaging stations, then 150,and, as the need for the data has increased,the SMS has expanded. Over the last 17 years, in excess of 5.5 million dollars has been spent to develop the infrastructure of the SMS. DWR operates and maintains over 450 data collection platforms(DCPs)on rivers, streams, reservoirs, ditches and canals to collect and transmit basic stream flow and water elevation data for water administration, including interstate compacts, and flood flow alerts. Collectively,these platforms and the computer equipment in Denver are the Satellite-linked Monitoring System (SMS). The USGS and other entities operate an additional 300+ sites in Colorado. The USGS and DWR are working to improve data availability and reduce duplication through improved gaging station effectiveness. The SMS provides basic water flow data to the staffs of the Division of Water Resources and Colorado Water Conservation Board; to many public and private entities, such as the Cities of Colorado Springs and Aurora,the Denver Water Board,the Arkansas River Compact Commission, Emergency Coordinators for most Colorado counties;to water rights holders; and to many recreatlonists such as fishermen, rafters,etc. Many programs of the DWR, such as the Dam Safety Program, Colorado River Decision Support System and the Rio Grande Decision Support System, and various river operations spreadsheets used by the seven Division Engineers for water administration were built to rely upon the real-time data acquired through the SMS. Water resources accounting programs utilizing the SMS include the Dolores Project,the Colorado-Big Thompson Project and the Fryingpan-Arkansas River Project. Also CWCB programs,such as Stream and Lake Protection, Flood Protection and Water Supply Protection utilize the real-time data. FY07 Accomplishments The CWCB provided$300,000 in FY07 for satellite telemetry equipment upgrade and replacement, and • stream gage refurbishment. Using$245,000 of these funds, 50 sets of satellite-linked monitoring equipment throughout Colorado were upgraded with high data rate satellite telemetry data collection platforms and stage measurement equipment,telemetry equipment and grounding equipment. The high data rate DCP upgrade program began in 2001. To date, 315 satellite monitoring gages, about 73%of the current total system, have been upgraded from 100 baud to 300 baud transmission speed. The balance of $55,000 was allocated to repair and refurbish stream gages throughout the State. Refurbishment projects were completed at the following stream gages in FY 07. Several other projects were initiated in FY07 but will carry over into FY08 for completion.
