5. USGS Water-Resource Role Science Agency, non regulatory Assess the quantity and quality of the Nations water supplies Collect data and conduct water-resources investigations to support local, State, and Federal needs Maintain nationwide hydrologic-data network and publicly available database

6. USGS Water Quality Related Activities in the Piceance Basin Southern Piceance Basin –Common Data Repository and Resource Assessment –USGS funded research proposal looking at the Distribution of Redox Processes and Ground-Water Ages in Aquifers of the Southern Piceance Basin. Northern Piceance Basin –Common Data Repository and Resource Assessment –Baseline Hydrologic Information Gathering for BLM Currently are conducting surface water monitoring (water quantity and quality) Will begin ground water monitoring and assessment in the next few months

7. Approach for Common Data Repository and Resource Assessment Assemble existing data from public and private sources Create relational database, standardize data, and make database accessible via internet Perform baseline assessment of available water resource data Develop regional monitoring strategies

8. Benefits of Common Data Repository and Resource Assessment Economic –Internally consistent database –Expand database for individual companies, agencies, stakeholders –Reduce data compilation and manipulation time –Improve efficiency of monitoring programs Management –Understanding leads to management tools (models) and effective best-management practices Public Outreach –Education and Openness Regulatory –Regional baseline –Natural variability versus human disturbance

9. Products of Common Data Repository and Resource Assessment Common Data Repository, web interface, and assessment report of baseline hydrologic conditions. Preliminary list of indicator parameters to understand energy effects on regional water resources. Regional monitoring plan –Streamline existing monitoring programs –Fill data gaps –Maximize utility for spatial and temporal assessment

10. We have created and continue to maintain similar products in the Eagle River, Blue River, Upper Gunnison, and Roaring Fork River watersheds The new product will be developed to meet unique interests of the general public, industry, and others Demo of Common Data Repository visit the Roaring Fork watershed site at http://co.water.usgs.gov/cf/roaringforkcf/default.cfm
