Yellow River near Brems, Indiana
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...

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...
Regression models for estimating sediment and nutrient concentrations and loads at the Iroquois River near Foresman, Indiana, March 2015 through July 2018
In 2015, the U.S. Geological Survey, in cooperation with the Iroquois River Conservancy District, deployed continuous water-quality monitors and began collecting representative discrete water-quality samples at the Iroquois River near Foresman, Indiana, streamflow-gaging station (U.S. Geological Survey station 05524500). By relating continuously monitored water-quality data and discrete water-qual

Environmental Setting of the Sugar Creek and Leary Weber Ditch Basins, Indiana, 2002-04
The Leary Weber Ditch Basin is nested within the Sugar Creek Basin in central Indiana. These basins make up one of the five study sites in the Nation selected for the Agricultural Chemicals: Sources, Transport, and Fate topical study, a part of the U.S. Geological Survey’s National Water-Quality Assessment Program. In this topical study, identifying the natural factors and human influences affecti

Agricultural Chemicals in Leary Weber Ditch Basin, Hancock County, Indiana, 2003-04
Leary Weber Ditch Basin, Hancock County, Indiana, is part of an Agricultural Chemicals: Source, Transport, and Fate study conducted by the National Water-Quality Assessment Program of the U.S. Geological Survey. Water-quality samples were collected in Leary Weber Ditch and in the major hydrologic compartments of the Leary Weber Ditch Basin during 2003 and 2004. Hydrologic compartments that contrib
