Amphibian Research and Monitoring Initiative

Published by National Park Service | Department of the Interior | Metadata Last Checked: January 25, 2026 | Last Modified: 2016-10-11T00:00:00Z
PI collected water quality samples from amphibian breeding sites at Gourley Pond, Finley Cane Sinks, the Sinks, and Gum Swamp to assist an amphibian monitoring initiative (GRSM-00105). The geological and cultural features and histories associated with each site are also described. April samples show that the waters have low pH (3.9-6.2), low specific conductance, and variable dissolved oxygen concentrations. Aluminum and iron levels were somewhat elevated, except at Gourley Pond, which gets much of its water from stream overflow. Only traces of mercury were present in the water samples. August samples were taken from the only two ponds with water at that time (Finley Cane #2 and the Sinks) but the results of their analysis is missing from the annual report.
