Abbreviated metric units used in this report: Chemical concentrations and some masses and volumes are given in metric units. Chemical concentration is given in milligrams per liter (mg/L), a unit expressing a unit of concentration of chemical constituents in solution as weight (milligrams) of solute per unit volume (liter) of water. In places, mass is given as kilograms (kg), and volume is given in liters (L). v Directions of Ground-Water Flow and Locations of Ground-Water Divides in the Lost River Watershed DIRECTIONS OF GROUND-WATER FLOW AND LOCATIONS OF GROUND-WATER DIVIDES IN THE LOST RIVER WATERSHED NEAR ORLEANS, INDIANA by E. Randall Bayless, Charles J. Taylor, and Mark S. Hopkins ABSTRACT water-level measurements were made at 11 of the 175 wells to evaluate the assumption The Mitchell Plain, a physiographic unit that these water levels provided an accurate in south central Indiana, is a classic example representation of the ground-water-level of karst topography. The town of Orleans, surface. The mean difference at the 11 Ind., which is in the Mitchell Plain, is a site of synoptic sites was 8.3 ft; the total drop in frequent flooding. Factors that enhance the water-table altitude across the study area is potential for flooding in Orleans may include about 180 ft.

In the eighth test, dye injected into INTRODUCTION a shallow storm-infiltration well apparently did not enter the conduit-flow-dominated part The Mitchell Plain, a physiographic unit in of the karst aquifer; instead, it moved through south-central Indiana, is a classic example of karst topography (Schneider, 1966). Karst topography a shallow, perched ground-water-flow system forms in humid subtropical and tropical climates to resurge in seeps and springs discharging to where carbonate bedrock is near land surface. The an intermittent tributary in the upstream area interaction between infiltrating precipitation that of the Lost River Watershed. contains weak, natural acids and the near-surface carbonate bedrock creates features that typify karst Dye-trace observations made during topography and drainage systems disappearing this study were coevaluated with similar streams, sinkholes, caves, and springs. The hydrologic system in areas of karst topography information from previous studies and indicate can be difficult to understand because surface- that (1) ground-water divides inferred from and subsurface-drainage systems are nearly the composite ground-water level-surface map inseparable. are accurate, (2) topographic divides south of Orleans, Ind., which is in the Mitchell Orleans coincide with ground-water drainage Plain (fig. 1), is a site of frequent flooding (Malott, divides, and (3) subsurface piracy has created 1952). Several hydrologic and anthropogenic noncoincident surface- and ground-water factors may contribute to the flooding. These factors include (1) location of the town in a karst divides in the area northeast of Orleans. valley, (2) a high runoff-rainfall relation for a Three drainage areas, each having loess- and residuum-covered area that drains into an occluded sink near the center of Orleans, and distinctive karst-drainage characteristics and (4) an overtaxed subsurface-drainage system affecting the drainage to and from Orleans, during periods of intense rainfall. were identified.
