Hydrologic/ Hydraulic Monitoring

A Super Gage is a conventional streamflow gage equipped with continuous water-quality monitors. Super gages provide real-time data specifically designed to improved our understanding of watershed processes and to address specific water-resource issues such as climate and land-use effects, water-related human health issues, floods and droughts, or hazardous substance spills. Our ability to model...

Water-quality “super” gages (also known as “sentry” gages) provide real-time, continuous measurements of the physical and chemical characteristics of stream water at or near selected U.S. Geological Survey (USGS) streamgages in Ohio, Kentucky, and Indiana. A super gage includes streamflow and water-quality instrumentation and representative stream sample collection for laboratory analysis. USGS...

Sanitation District #1, located in Northern Kentucky, in cooperation with the USGS, established a stream gaging network to adhere to requirements of a Consent Decree. This legally-binding document between Sanitation District #1 and state and federal environmental regulators helps to increase responsible watershed management.

In September 2015, Kentucky Water Science Center scientists, in cooperation with the U.S. Army Corps of Engineers (USACE), began investigations on two Kentucky lakes and tailwaters. Continuous water quality is collected at both lake and tailwater sites and gage height is monitored at the tailwater sites.

Ohio, Kentucky, and Indiana Water Science Center is monitoring the effects of best management practices (BMP's) on baseflow and storm runoff in the Black Creek watershed near Harlan, IN. We will be sampling water-quality intensively for 5 years from overland field, subsurface tile, and in-stream runoff events. Results will be used to model the effectiveness of BMP’s in reducing nutrient and...

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...

The U.S. Department of Agriculture Natural Resources Conservations Service and the U.S. Environmental Protection Agency have focused part of the National Water Quality Initiative (NWQI) on the School Branch watershed. The USGS is collaborating, through a Clean Water Act Section 319 grant, with the Indiana Department of Environmental Management to accomplish NWQI nonpoint-source water-pollution...

Indiana and Kentucky scientists have produced new low-flow statistics for Indiana streams, specifically for 7-day, 10-year low flow (7Q10); 30-day, 10-year low flow (30Q10); 1-day, 10-year low flow (1Q10); and harmonic mean streamflow. The low-flow statistics are critical for the state of Indiana to administer the National Pollutant Discharge Elimination System (NPDES) permit program, watershed...

Adult bighead, silver, and hybrid carp are invavsive species of fish that spread quickly once they are established in a water body. These carp damage habitat and reduce water-quality for native fish. Invasive carp have been confirmed within the Wabash River basin for at least 15 years. Scientists and natural resource managers are extremely concerned about the carp migrating to the Great Lakes...

Scientists research biology, botany, microbiology, habitat, climate, water quality, and other fields to achieve a comprehensive view of ecosystems and their health. Ecosystems can be easily stressed by human activities, climate change, sediment, nutrients, contaminants, and many other variables. Ecosystem monitoring is critical to ecosystem health and answers important questions about the...
