Vermillion River near Vermillion OH
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...
Kankakee River at Davis, IN
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...
Yellow River near Oak Grove, IN
"Super" gages provide real-time, continuous water-quality information for rivers and streams at selected Ohio, Kentucky, and Indiana U.S. Geological Survey (USGS) streamgages. By combining discrete and continuous data in statistical models, USGS scientists can continuously estimate constituents that are difficult to measure in real-time. For example, in-stream turbidity sensors are often used to...

Maumee River at Antwerp, OH
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...
Indiana Harbor Canal at East Chicago, IN
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...
Super Gage Network
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...
Using continuous water-quality measurements and discrete data to identify the drivers of HABs in lakes and tailwaters In Kentucky and Indiana
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.
Harmful Algae Blooms (HABs)
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...
