SUB-BASIN DELINEATION NEAR TURNHOLE BEND, MAMMOTH CAVE NATIONAL PARK
A dye trace study is designed to confirm flow paths from the surface to springs along the Green River. Four surface sites were selected and injected with unique dyes. All known springs in the area were fixed with activated charcoal filters to monitor the re-emergence of dye after establishing background levels. Fluorescence analysis determine which dyes were detected in each spring.
This study seeks to establish the boundaries on a small drainage sub-basin near the Turnhole Bend area of Mammoth Cave National Park. This research will yield a higher level of resolution of hydrologic connectivity than the state-wide map from the Kentucky Geological Survey or the previous efforts of Mammoth Cave National Park.
