EPT Indexing

EPT indexing is a method of assessing the biological health of a stream. Aquatic macro-invertebrates (larval and pupae stages of bugs that live in the water) are collected from these three orders, identified to the species level: Ephemeroptera (mayflies), Plecoptera (stoneflies), Tricoptera (caddisflies).

Many of these organisms are not tolerant to pollution, so their presence in a stream is a cumulative measure of stream health. For the full report of the assessment of the Bonne Femme streams, download the final reports in PDF format.

Dye Tracing

Dye tracing is a method of determining 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. The Bonne Femme Watershed Project Dye Trace Final Report discusses these two dye trace experiments performed by the Bonne Femme Watershed Project from 2003 to 2004.
