| Abstract | Since land use is carefully managed within U.S. national parks, the most significant negative impacts to resources, including impacts to water quality, air quality, and from exotic species, often come from external sources. To identify water quality threats it is critical to define the region that drains to a park, as land use within that area is the principal source of water contamination. Compared to most national parks, determining drainage to Mammoth Cave National Park (MACA) is relatively complicated due to the highly developed karst landscape/ aquifer system so integral to MACA. While in general the area draining to MACA is well known (Meiman, 2005), we present here the most comprehensive single map so far developed of drainage to MACA (Figure 1), that for the first time includes corrections to areas of the catchment boundaries that were influenced by differences between those of the Hydrologic Unit Code (HUC) maps from the US Geological Survey (USGS) National Hydrography Dataset (NHD) and subsurface karst basin boundaries based on the Kentucky Geological Survey (KGS) Karst Atlas Maps (Osterhoudt, 2014). NHD map catchment boundaries are based on surface topography, which can be misleading where drainage boundaries cross sinkhole plains in karst settings, as in areas of the Green River upstream from MACA (Figure 2). An extensive program of dye tracing over more than four decades (Currens and Ray, 1999) has provided the necessary flow data to make these corrections. Four principal regions drain to MACA: 1) surface drainage from the Green River valley to the east, 2) surface drainage from the Nolin River valley to the north, 3) subsurface karst flow into the Green River from the south, and 4) subsurface karst flow into the Green River from the North. Green River surface drainage includes the river’s floodplain crossing the karst sinkhole plain. Figure 1: Map showing drainage areas upstream from Mammoth Cave National Park. |
