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 Monitoring Schedule http://cms.lcra.org/ FY 2008 Monitoring Sites • San Antonio – Nueces Coastal Basin – NRA • 12 sites – TCEQ • 12 sites FY 2008 Monitoring Sites • Nueces Basin – NRA • 18 sites – TCEQ • 17 sites 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 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 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) New Listings on the 303d list • 2117 Frio River Above Choke Canyon Reservoir (bacteria) 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 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 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 2008 Basin Summary Report – Draft available for review – Comments by April 30 – Comments to Rocky Freund – Email: [email protected] – Fax: 361-825-3195 – Mail: Nueces River Authority 6300 Ocean Drive – Unit 5865 Corpus Christi, TX 78412-5865 Basin Summary Report Format • Watershed Overview • Segments and Assessment Units • Active Wastewater Permits Permit Numbers Discharge Information Basin Summary Report Format Cont. • Sampling History All stations throughout history Current Stations 2008 Monitoring Stations AU 2104_ 03 Site Date Range 12974 – At FM 624 1983, 2002 – 2004 12973 – SH 16 south of Tilden 2104_ 02 2104_ 01 1972 – Present 17897 – Approx. 13.9 km downstream of SH 16 on Smith Lease 12972 – FM 1042 bridge 1.2 miles north of Simmons Entity Frequency Parameter Groups AU Site Entity Frequency Parameter Groups 2105-02 12973 – SH 16 south of Tilden NRA Quarterly Conventional, Bacteria, Field 2105_01 12972 – FM 1042 bridge 1.2 miles north of Simmons NRA Quarterly Conventional, Bacteria, Field 2002 – 2004 1968 – 1992, 2002 Present Basin Summary Report Format Cont. • Flow Information 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.
