EPT Indexing
EPT indexing is a method of assessing the biological health of a stream. Aquatic Macroinvertebrates (larval and pupae stages of bugs that live in the water) are collected; from these, three orders (Ephemeroptera (mayflies), Plecoptera (stoneflies), and Tricoptera (caddisflies)) are identified to the species level. Many of these organisms are not tolerant to pollution, so their presence in a stream is a cumulative measure of stream health.

Dye Tracing
Dye tracing is a method of determing where water flows in underground karst conduits. The Project completed dye tracing to further delineate the surface areas that supply water to the two major cave systems. For more info, see:
