EXPLANATIONThis map shows karst ground-water basins in the Somerset quadrangle, determined primarily by ground-water tracer

studies. It can be used to quickly identify the ground-water basins and springs to which a site may drain. Major springsand the relative size of their catchment areas can be evaluated for potential as water supplies. The map also serves asa geographic index to literature on karst ground water in the area.

This map is designed for regional and preliminary hydrologic investigations. Features such as springs and swalletsare much too small to precisely locate on this map with a scale small enough to show regional relationships. The useris referred to the literature for detailed site descriptions. The data used to compile this map were obtained by numerousinvestigators over the last 25 years. The underflow spring draining a ground-water basin is assigned a unique identificationnumber, referred to as the AKGWA number (Assembled Kentucky Ground Water Database). Individual basins areidentified by the underflow spring name and AKGWA number. The authors of tracer data are identified by numberin the “Data Source” column of the key, and are listed in “References Cited” in order of publication or research date.

Although ground-water flow routes shown here have been established by tracer studies, with the exception of mappedcave streams, the precise flow paths are unknown and are inferred or interpreted using water-level data, geologicstructure, or surface features. Arrows show the direction of ground-water flow and tracer recovery locations. Conduitflow is illustrated as either thick trunk-flow lines or thin tributary-flow lines. The locations of some ground-waterbasins are inferred, based on the existence of a significant spring system and the delineation of adjacent basins. Theposition of ground-water basin boundaries should be considered approximate because of the map’s scale and becauseboundaries can shift during high-water conditions. Also, excess flow may exit or enter a basin via surface or subsurfaceoverflow routes. Additional overflow routes probably exist. Although most of the results of ground-water tracingshown on this map were obtained during moderate- or high-flow conditions, the ground-water basins are illustratedin base flow because base flow is the most common flow condition. The main spring draining the basin is assumedto be an underflow spring that preferentially drains base flow. Overflow springs discharge during high flow.1 Generally,names of ground-water basins are derived from these main springs. Not all additional springs are shown because ofthe small map scale.

DISCLAIMER: This map is subject to revision upon receipt of new hydrologic data. The unshaded area (shown inwhite on the map) is karst. The shaded area (shown in light brown) is largely underlain by noncarbonate rocks andhas minimal development of karst. Karst features are only shown in those areas where tracer tests have been conducted.The user should consult the “References Cited” for additional information.1Worthington, S.R.H., 1991, Karst hydrogeology of the Canadian Rocky Mountains: Hamilton, Ontario, McMasterUniversity, Ph.D. dissertation, 380 p.
