Monitoring Grades
Understanding the physical, chemical, and biological features of Glenns Creek
The interactive map below summarizes monitoring efforts performed between March 2021 and February 2022 according to an approved quality plan to produce data to support a watershed plan and a formal designated use assessment. Monitoring was conducted by the Kentucky Water Research Institute and the University of Kentucky Cooperative Extension Service at nine locations over a one-year period. Sampling was conducted monthly for E. coli, bulk parameters, nutrient parameters, metal parameters, and alkalinity parameters. Sites were selected to represent watershed areas based on land use changes and significant tributaries. The Kentucky Division of Environmental Program Support analyzed all samples except E. coli, which was analyzed by the Kentucky Division of Water. Habitat and aquatic macroinvertebrates were assessed by the Kentucky Division of Water in April and July 2021.
Results were compared against the criteria below, with grades assigned based on frequency of exceedance:
Results indicate that E. coli, nitrogen, phosphorus, dissolved solids/conductivity, pH, chloride, iron, lead, habitat, and macroinvertebrates all exceeded benchmarks at least once during the monitoring period. The plan identifies measures to reduce E. coli, nitrogen, phosphorus, and dissolved solids and opportunities to improve habitat and macroinvertebrate scores.
