Rural/Urban Water Quality

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...

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...

What is a Super Gage? A gage at which continuous flow and water level are determined, along with continuous traditional water-quality (water temperature, specific conductance, pH, dissolved oxygen, and/or turbidity) and either of the following criteria: at least one other less-traditional continuous water-quality parameter (orthophosphate, nitrate concentration) and/or where surrogates (developed...

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.

The USGS has the principal responsibility within the federal government to provide the hydrologic information and understanding needed by others to achieve the best use and management of the nation’s water resources. Basic data are the key to solving many water-quantity or -quality problems. Ohio, Kentucky, and Indiana operate a large hydrologic network across the three states, collecting surface...

Cyanobacterial harmful algal blooms (HABs) are increasingly a global concern because HABs pose a threat to human and aquatic ecosystem health and cause economic damages. Toxins produced by some species of cyanobacteria (called cyanotoxins) can cause acute and chronic illnesses in humans and pets. Aquatic ecosystem health also is affected by cyanotox­ins, as well as low dissolved oxygen...

One of the strongest ways to ensure that science is done effectively and efficiently in the midst of ever decreasing budgets is to collaborate.

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...

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...

Starting in 2000, the U.S. Geological Survey partnered with the Indiana Department of Environmental Management, the National Atmospheric Deposition Program, and the Lake Michigan Air Directors Consortium to investigate and monitor mercury in the environment in Indiana. This web page provides a list of publications and links to statewide studies of mercury in Indiana and regional mercury studies...
