ADEM's Monitoring Activities in the Tallapoosa River Basin: 2005 and 2010 6th Annual Tallapoosa State of Our Watershed Conference Alex City, Alabama 25 May 2010 Lisa Huff – ADEM Field Operations Division adem.alabama.gov
ADEM’s Monitoring Summary Reports • Presentation Outline • Rivers and reservoirs program and reports (RRMP) • Rivers and streams program and reports (RSMP) • 2005 RSMP reports and supporting documents CD • Monitoring data and reports in the assessment process • Other uses of data • 2010 sampling in the Tallapoosa R. basin • Comments and questions
2005 RRMP Summary Reports: Purpose of the reports • Summarize all monitoring data collected within each reservoir during 2005 and 2006 • Compare these data to ADEM’s historical data and established criteria • Evaluate trends in mean lake trophic status using ADEM’s entire RRMP dataset • Communicate this information • Tallapoosa Reports: • Martin • Harris • Thurlow/Yates
2005 RRMP Summary Reports: Information in the reports Sampling locations • Mainstem Stations • Tributary Embayment • Riverine Stations • Background information • Program history • CWA §303(d)/TMDL status • Results • Monthly (April-October) concentrations • Mean, median, min, and max concentrations • Indicators • Total nitrogen • Total phosphorus • Chlorophyll a • Total suspended solids • Dissolved oxygen • Temperature • Algal growth potential tests • Trophic state index • Contact information
2005 RRMP Summary Reports: Information in the reports Figure 7. Mean chlorophyll a concentrations measured at ADEM’s mainstem Harris Reservoir stations, 1991 through 2005. Chlorophyll a criteria applies to the growing season mean of the mid and lower stations only.
2005 RRMP Summary Reports: Information in the reports Figure 4. Total nitrogen (TN), total phosphorus (TP), chlorophyll a (chl a) and total suspended solids (TSS) of the mid station in Harris Reservoir, April-October 2005. Each bar graph depicts monthly changes in the variables at the upper station. The historic mean and min/max range are also displayed for comparison. Nutrients and TSS are plotted vs. discharge (R.L. Harris Dam discharge data).
2005 RRMP Summary Reports: Information in the reports Figure 11. Trophic State Index values from critical period sampling (August sampling only) from 1985 to 2005.

ADEM Monitoring Strategy:2005-2009 • Monitoring Strategy Objectives • Estimate overall water quality • Estimate water quality trends • Assess water quality • Support Management Decisions • Assess Criteria Compliance • Evaluate program effectiveness • Develop, adopt, or revise WQS • Develop criteria & indicators
ADEM Monitoring Strategy:2005-2009 • Data collected at majority of wadeable, flowing rivers and streams locations: • 1X habitat and macroinvertebrate assessments • Monthly in situ parameters and water samples, March-Oct • Semi-monthly total and dissolved metals, March-Oct Macroinvertebrate Assessments Periphyton Assessments Fish Community Assessments
2005 RSMP Summary Reports: Purpose of the reports • Summarize all monitoring data collected at each location • Interpret results of biological assessments using ADEM’s Macroinvertebrate Bioassessment Indices • Communicate this information
2005 RSMP Summary Reports: Information in the reports • Sampling location • Why the site was sampled • Watershed condition and characteristics • Reach characteristics • Habitat assessment results • Macroinvertebrate bioassessment results • Summary of 8 monthly water samples • Contact information
2005 RSMP Summary Reports: Results from the ACT • 30 Bioassessments • 1 Excellent • 8 Good • 7 Fair • 6 Poor • 2 Very poor • 6 Unassessed
Assessment Process 2005 RSMP Summary Reports: Part 1 of the assessment process • Categories • 1: fully meeting all use classifications • 5: not meeting one or all use classifications (303d list) • 2: Insufficient data • 2a: available data indicate impairment • 2b: available data do not indicate impairment • 3: No data available • 4: Waterbody impaired but remediation plan in place • 4a: Approved TMDL • 4b: Other action expected to result in attainment • 4c: impairment not caused by pollutant Monitoring Assessment Remediation (BMPs,TMDLs) 303d List
ADEM Monitoring Strategy:2005-2010 • Sampling Planned to develop a dataset that can be used to develop metrics, indices, and criteria • Watershed-based sampling to link each assessment result to conditions in the watershed
2010 Monitoring Sites in the Tallapoosa River Basin • 65 Stations by Project • Intensive Basin Assessments • Rivers and Reservoirs • Rivers and Streams • TMDLs • Pepperell Branch • Cubahatchee Creek • Parkerson Mill • Longterm trend stations • Use Support Assessments • 2010 Category 2B waters • Tallapoosa R Basin Nutrient Criteria Project
NW Macroinvertebrate Assessments • Tallapoosa Nutrient Criteria Development • L. Tallapoosa R. (LTRR-1) • Tallapoosa R. (TA-1) • Tallapoosa R. (TART-1) • Sougahatchee Ck. (SOGL-5) • Tallapoosa R. (TLRC-1) • Longterm Trend Stations • Tallapoosa R. (TA-1) • Tallapoosa R. (TART-1) Little Tallapoosa R. upstream of Randolph County RD. 49 (us of gage)
ADEM Monitoring Programs • Biological Monitoring Program (BMP) • Nonwadeable assessment development • Fish and periphyton assessment development • Fish Tissue Monitoring Program (FTMP) • Increasing annual effort • Multiple species collection • Increase in collection of nearshore marine species. • Coastal Monitoring Program (CMP) • Expand trend station network to include all estuaries and their principal tributaries. • Revive coastal watershed surveys. • Heavy ADEM participation in the Gulf of Mexico Alliance (GOMA) • Wetland Monitoring Program (WMP) • Implementing multi-state pilot project in 2010 • Strategy Revision scheduled for 2010 • Will include details for all water quality monitoring programs.
