Overview of the Clean Rivers Program
• Funding and Allocation of Resources– State fee-funded– $9 Million State-Wide for 2 years– NRA: $548,272
• Project Administration – 21%• Quality Assurance – 4%• Water Quality Monitoring – 39%• Data Management – 13%• Data Analysis and Reporting – 9%• Stakeholder Participation and Public Outreach – 13%• Special Projects – 1%
Deliverables
• Quality Assured Data
• Basin Highlights Report
• Basin Summary Report (every 5th year)
• Data Accessibility via Website
Overview of the Clean Rivers Program
• Role of the Steering Committee and Stakeholders– Objective 4: Inform and Engage Stakeholders
• 1. Give stakeholders the opportunity to contribute their ideas and concerns through steering committee meetings, public meetings, and/or other forums
• 2. Participate in public information and education activities to increase stakeholder involvement in the program and interest in water quality issues
• 3. Communicate information on water quality issues to stakeholders so that priorities may be set considering local, regional, state, and federal needs
• 4. Support stakeholders, volunteers, and other programs in addressing water quality issues
• 5. Provide information requested by interested parties and disseminate information via the Internet
Overview of the Clean Rivers Program
• Water Quality Assessment– 2006 – December 1, 1999 – November 30, 2004– 2008 – December 1, 1999 – November 30, 2006
• Water Quality Inventory– Concerns – 305(b) list– Impairments – 303(d) list
FY 2008 Monitoring Sites• Nueces – Rio Grande Coastal Basin

Copano Bay/Aransas and Mission Rivers BacteriaTMDL for bacteria (2003)
To support this TMDL:
•TSSWCB and NRA funding for more monitoring
•6 events/up to 30 sites (stream sites and WWTP)/year (4 high flow/wet events, 2 low flow/dry events)
•3 consecutive days
•More sites chosen in upper reaches of watershed
•TWRI and TCE educational programs and assemble and evaluate existing information
•University of Texas model of watershed

pH (su): 58 samples, ranging from 7.5 to 8.6, median value is 7.8, 0 values outside criteria range of 6.5 to 9, decreasing trend. There is a fairly large variation in pH values, but it does not seem to correlate with seasons or changes in flow. The data indicates a decreasing trend. The values are still well above the minimum criteria value and are not a concern at this time. However, this parameter needs to be watched and understood so that it does not become a problem.
