  1. Colorado’s Surface Water Monitoring System Colorado Division of Water Resources

  2. History • 1881 - State Hydraulic Engineer • Water Rights Administration • Stream Flow and Diversion Measurements • Reservoir Capacity, Cost and Location • First gaging station installation • 1884 First chart recorder installation • 1969 - Division of Water Resources • Public Safety • Ground Water Permitting • Interstate Compacts • Hydrographic and Satellite Monitoring

  3. Hydrographic and Satellite Monitoring Branch • 28 project staff • Gaging station operations and maintenance • Stream flow measurement • Electronic equipment maintenance • Records publication • Software development and web administration • Manage surface water monitoring system • Satellite-linked starting in 1985 • VAX and DB2 database • Retrieve data from external sources

  4. Water administration/distribution Compact administration Water storage and release Flood warning/monitoring Dam safety Recreation/safety Environmental monitoring Minimum stream flow Certified final stream flow records Hydrologic modeling Water rights analyses, exchanges, transfers Litigation Wildlife and fisheries Water quality Hydrographic and Satellite Monitoring Branch

  5. Data Collection Overview

  6. Surface Water Monitoring System Data Collection • DWR Data Collection • 456 DWR gaging stations on satellite telemetry • 62 cooperator gaging stations • Federal agencies (USBR, USACE, NWS) • Local entities (Colorado Springs, Aurora, etc.) • Stream flows and diversions • Reservoir levels • Environmental data (precipitation, air and water temperature) • Water quality parameters (cooperators) • Data from external providers • 375+ external stations • U.S. Geological Survey • Water conservancy districts (NCWCD, LSPWCD, SVLHWCD)

  7. Surface Water Monitoring System Data Collection • Satellite Telemetry • 509 NESDIS IDs (411 active) • 86% are High Data Rate (HDR) • Decode 53 cooperator IDs • 10,700+ transmissions /day • 105,500+ data values/day • 32,000+ diagnostics values/day (signal strength, battery voltage, error codes) • Data provider stations • Via web services • Data automation services • 45,200+ data values / day

  8. La Plata and Cherry Creek Ditch Rio Grande Above the Mouth of Trinchera Creek Cheeseman Reservoir

  9. Data Processing Overview

  10. Decode and Processing Server • Data Retrieval & Decoding • Ilex Local Readout Ground Station • Ilex DCS Real-time Process (self-timed and random data) • Ilex DCS Diagnostics Process (raw transmission string) • Data Processing Services • Data Loader Service • Data Processor Service • Diagnostics Service • USGS Data Service • NCWCD Data Service • System Monitor • Monitor Service

  11. Database Server • Microsoft SQL Server 2000 • Data storage • Update Decodes database • System configurations • System status • Data Processing (Data Transformation Services) • FTP export DTS

  12. System Administration • Hydrologic Management System (webHMS) • Web accessible application • Configure station setup • Manage gaging station lists • Manage satellite transmission configurations • Update Decodes database • View system and station diagnostics • Reporting

  13. webHMS – Station configuration Manage station setup Change platform Configure station sensor data Reporting

  14. webHMS – Diagnostics System status View diagnostics Data transmission strings

  15. Colorado’s Surface Water Conditions Web Site • Provide near real-time telemetry data to personnel and the public • Detailed graphs • Tabular data • Approximately 3 million page views per year

  16. Colorado’s Surface Water Conditions • Customized user station lists • Statistics • Analysis / Comparison Tools

  17. Telephony Solutions • Alert Notification System • Dials out to subscribers • User subscribed station list • Informs subscriber of “red flag” conditions (minimum, maximum or rate of change) • WaterTalk • Inbound stream flow condition requests • Approximately 90,000 inbound call per year Active Call Center

  18. Automated Data Services • Web Service • ColoradoWaterSMS • Expose provisional data to Cooperators, Application Developers, and other data harvesters • .NET platform, can be consumed by any SOAP client • Web Site • URL - http://www.dwr.state.co.us/SurfaceWater/data/export_tabular.aspx • FTP Site • Data exported from SQL Server using scheduled Data Transformation Services (DTS) packages • Being phased out in favor of web services
