Groundwater resources in southern Michigan, northeastern Indiana, and northwestern Ohio, have been a recurring subject of interest related to sources of public, irrigation, and other water supplies and the potential of glacial deposits to supply water to adjacent parts of Ohio. The glacial deposits that are part of the aquifer system informally known as the “Michindoh aquifer” are a principal...

Groundwater level is monitored at numerous observation wells across Ohio, Kentucky, and Indiana. Data are collected in real-time, continuous, and periodically. These data support decisions by local, state, and federal cooperators to balance diverse and growing demands for water resources in our three states. These demands include major resource management challenges like groundwater availability...

State and local agencies in Ohio (and to a limited extent, the USGS) collect, research, interpret, and disseminate groundwater data to characterize the groundwater resources of the State. To address these needs, the Ohio Department of Natural Resources (ODNR) and the Miami Conservancy District (MCD) monitor groundwater levels for more than 140 wells throughout Ohio. Personnel from the USGS Ohio...

Green infrastructure (GI) is a retrofit or as-built approach to managing stormwater as near its source as possible by minimizing impervious surfaces and promoting more natural infiltration and evapotranspiration than is typically associated with developed areas. There are a variety of GI stormwater control measures, including rain gardens, bioretention features, and pervious pavements. At the St...

Increased stormwater runoff and associated problems, including increased pollution and flooding, have led to engineered attempts to return urban areas to a more natural water cycle. The USGS, in cooperation with the Franklin Soil and Water Conservation District and the City of Columbus, is collecting hydrologic data to determine the effectiveness of recently installed rain gardens near Griggs...
