MonitoringLocationDescriptionText This station was at Green River at Nolin River. The Green is the regional base-level stream as is sampled just upstream from its confluence with the Nolin. Aquatic fauna of the Green, just within the park, ranks among the most diverse in North America. Six species of freshwater mussels are listed as Endangered, and four more are classed as Category 2, as are two species of fish. The Green River, with more than 80 species of fish (including five endemics), and 170 species of benthic macroinvertebrates, including 53 species of freshwater mussels, has been designated an Outstanding Resource Water by the Kentucky Environmental Protection Cabinet. The flow at this site originates primarily as surface water from the upper Green River, and its chemistry reflects those land-uses rather than local influences.
