United States Geological Survey (USGS). The current request is part of a continuing annual request for <br /> funds to support this program. <br /> Background <br /> The Satellite-linked Monitoring System (SMS) has been operating since 1985, starting with 82 linked gaging <br /> stations. As the need for the data has increased, the SMS has expanded. Since inception, in excess of 7.5 <br /> million dollars has been spent to develop the infrastructure of the SMS. Currently, DWR operates and <br /> maintains over 500 data collection platforms (DCPs)on rivers, streams, reservoirs, ditches and canals to <br /> collect and transmit basic stream flow and water elevation data to support the Division's primary mission of <br /> water rights administration. Included is support of interstate compact administration, and flow alerts based <br /> on parameter thresholds (e.g., low flow alerts in support of CWCB ISF programs, high flow alerts in support <br /> of flood protection decision making and flood warning, rate of change alerts below dams and reservoirs). <br /> Collectively, these platforms and the computer equipment in Denver are the Satellite-linked Monitoring <br /> System (SMS). The USGS and other entities operate an additional 300+ sites in Colorado. The USGS and <br /> DWR are working to improve data availability and reduce duplication through improved gaging station <br /> effectiveness. The SMS provides basic water flow data to the staffs of the Division of Water Resources and <br /> Colorado Water Conservation Board; to many public and private entities, such as the Cities of Colorado <br /> Springs and Aurora, the Denver Water Board, the Arkansas River Compact Commission, Emergency <br /> Coordinators for most Colorado counties; to water rights holders; and to many recreationists such as <br /> fishermen, rafters, etc. Many programs of the DWR, such as various river operations analysis spreadsheets <br /> used in each of the seven DWR Division offices for water administration, and the DWR Safety of Dams <br /> Program rely upon the real-time data acquired through the SMS. Water resources accounting programs <br /> utilizing the SMS include the Dolores Project, the Colorado-Big Thompson Project and the Fryingpan- <br /> Arkansas River Project. CWCB programs, such as Stream and Lake Protection, Flood Protection and <br /> Water Supply Protection also utilize the real-time data. <br /> FY2012-13 Funding Request <br /> Replacement of Satellite Telemetry Equipment. For FY2012-13, the DWR request for the replacement of <br /> out-dated DCPs and upgrade of associated satellite telemetry equipment is $245,000. <br /> The National Oceanic and Atmospheric Administration (NOAA)operates the GOES satellite via which <br /> stream stage and water body surface elevation data are telemetered from remote sites to the central <br /> computer in Denver. The use of this satellite and all the ancillary hardware and software, including staffing, <br /> is valued at over$500 million dollars. The State of Colorado has been able to utilize this system at no <br /> charge. By 2001, the use of the GOES satellite system had increased to the point where demand had <br /> begun to exceed satellite channel capacity. NOAA, therefore, mandated that all DCPs using the GOES <br /> satellites for data transmission must be upgraded by 2013 to transmit data at 300 baud as compared to 100 <br /> baud rate of first generation DCPs. DWR has completed the upgrade to high data rate of all DCPs it owns <br /> and operates on the satellite monitoring system. DWR is actively engaging entities that own, and are <br /> responsible for the few remaining DCPs on the network needing this upgrade, to complete their upgrades by <br /> the 2013 deadline. An important benefit of the high data rate upgrade program has been the more frequent <br /> (from once per four hours to once per hour)transmission of data from remote sites to the central computer. <br /> This has resulted in near'real-time' data on the system. <br /> NOAA, through the Satellite Telemetry Interagency Working Group (of which the State of Colorado is a non- <br /> voting member)continues to explore means of increasing the capacity of the GOES satellite system. The <br /> next technology upgrade is implementation of the narrow band transmission protocol, which is expected to <br /> be launched in late 2011. This improvement will cut the band width of each telemetry assignment from 300 <br /> kHz to 150 kHz, effectively doubling the satellite transmission capacity. Most GOES transmitter <br /> manufacturers have agreed this will be a firmware upgrade to their equipment. However, it is now apparent <br /> that platforms deployed in the field will need to be replaced. Those platforms that are compatible with <br /> narrow band protocol will then be brought back to the electronics lab, have their firmware upgraded and then <br /> be subjected to a benchtop certification test protocol. Many early high data rate DCPs procured and <br /> installed by DWR beginning in 2001 are not compatible with the narrow band protocol and will need to be <br />
