  2. CRP Area of Responsibility 30,500 square miles3 Basins 23 Watersheds 45 Segments

  3. 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%

  4. Deliverables • Quality Assured Data • Basin Highlights Report • Basin Summary Report (every 5th year) • Data Accessibility via Website

  5. 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

  6. 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

  7. Monitoring Schedulehttp://cms.lcra.org/

  8. FY 2008 Monitoring Sites • San Antonio – Nueces Coastal Basin • NRA • 12 sites • TCEQ • 12 sites

  9. FY 2008 Monitoring Sites • Nueces Basin • NRA • 18 sites • TCEQ • 17 sites

  10. FY 2008 Monitoring Sites • Nueces – Rio Grande Coastal Basin • NRA • 3 sites • 2 24-DO sites on Arroyo Colorado • CWQM on Petronila Creek • TCEQ • 33 sites • City of Abilene (Boy Scouts of America) • 1 site

  11. Use Assessment &Monitoring Parameters • Aquatic Life • Dissolved Oxygen • Public Water Supply • Chloride • Sulfate • TDS • Contact Recreation • Bacteria • General Use • Water Temperature • pH • Ammonia • Nitrogen • Phosphorus • Fish Consumption • Fish Tissue © Shedd Aquarium/www.fishphotos.org

  12. Delistings from the 303d list • 2104 Nueces River Above Frio River (depressed DO) • 2107 Atascosa River (impaired habitat) • 2113 Upper Frio River (impaired habitat) • 2116 Choke Canyon Reservoir (bacteria) • 2117 Frio River Above Choke Canyon Reservoir (depressed DO) • 2204 Petronila Creek Above Tidal (chloride, sulfate, TDS) • 2485 Oso Bay (bacteria)

  13. New Listings on the 303d list • 2117 Frio River Above Choke Canyon Reservoir (bacteria)

  14. Continued Listings on the 303d list • 2001 Mission River Tidal – bacteria • 2003 Aransas River Tidal – bacteria • 2004A West Aransas Creek (unclassified) – bacteria • 2106 Nueces/Lower Frio River – TDS • 2107 Atascosa River – bacteria, impaired fish community, depressed DO • 2108 San Miguel Creek – bacteria • 2109 Leona River - bacteria • 2113 Upper Frio River – impaired fish community, impaired macrobenthic community • 2116 Choke Canyon Reservoir – depressed DO • 2117 Frio River Above Choke Canyon Reservoir – bacteria • 2201 Arroyo Colorado Tidal – bacteria, depressed DO • 2202 Arroyo Colorado Above Tidal - bacteria

  15. Status/updates Water Quality Standards • TCEQ website: • 1997 Texas Surface Water Quality Standards • 2000 Texas Surface Water Quality Standards • EPA Approval of 2000 Standards Timeline • Future Revisions of the Texas Surface Water Quality Standards • Surface Water Quality Standards Workgroup

  16. Copano Bay/Aransas and Mission Rivers Bacteria • TMDL 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 • Texas A&M CC BST

  17. 2008 Basin Summary Report • Draft available for review • Comments by April 30 • Comments to Rocky Freund • Email: rfreund@nueces-ra.org • Fax: 361-825-3195 • Mail: Nueces River Authority 6300 Ocean Drive – Unit 5865 Corpus Christi, TX 78412-5865

  18. Basin Summary Report Format • Watershed Overview • Segments and Assessment Units • Active Wastewater Permits • Permit Numbers • Discharge Information

  19. Basin Summary Report Format Cont. • Sampling History • All stations throughout history • Current Stations • 2008 Monitoring Stations • Entity • Frequency • Parameter Groups

  20. Basin Summary Report Format Cont. • Flow Information

  21. Basin Summary Report Format Cont. • Water Quality Analysis and Trend Analysis • TDS, chloride, sulfate for entire segment • Analysis for each AU (min, max, median, discussion) • DO • pH • Ammonia • Nitrate+Nitrite • OP • Total Phosphorus • Chlorophyll a • TSS • Bacteria (E.Coli, Enterococcus) 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.
