High frequency data exposes nonlinear seasonal controls on dissolved organic matter in a large watershed

We analyzed a five year, high frequency time series generated by an in situ fluorescent dissolved organic matter (fDOM) sensor installed near the Connecticut River’s mouth, investigating high temporal resolution DOM dynamics in a larger watershed and longer time series than previously addressed. We identified a gradient between large, saturating summer fDOM responses to discharge and linear, subdu

Nitrogen concentrations and loads for the Connecticut River at Middle Haddam, Connecticut, computed with the use of autosampling and continuous measurements of water quality for water years 2009 to 2014

The daily and annual loads of nitrate plus nitrite and total nitrogen for the Connecticut River at Middle Haddam, Connecticut, were determined for water years 2009 to 2014. The analysis was done with a combination of methods, which included a predefined rating curve method for nitrate plus nitrite and total nitrogen for water years 2009 to 2011 and a custom rating curve method that included sensor

Chloride concentrations, loads, and yields in four watersheds along Interstate 95, southeastern Connecticut, 2008-11: factors that affect peak chloride concentrations during winter storms

Chloride (Cl-) concentrations and loads and other water chemistry characteristics were assessed to evaluate potential effects of road-deicer applications on streamwater quality in four watersheds along Interstate 95 (I–95) in southeastern Connecticut from November 1, 2008, through September 30, 2011. Streamflow and water quality were studied in the Four Mile River, Oil Mill Brook, Stony Brook, and

Data on Nitrogen Concentrations and Loads for the Connecticut River at Middle Haddam, Connecticut, Computed with the Use of Auto-Sampling and Continuous Measurements of Water Quality, 2008-2014

This U.S. Geological Survey data release presents tabular daily data on nitrate plus nitrite nitrogen and total nitrogen loads for the Connecticut River at Middle Haddam, Connecticut, from December 6, 2008, to September 30, 2014. The data release contains total nitrogen concentration estimates at 15-minute intervals from December 2011 to September 2014. The data release also includes tabular infor

Surface Water Quality Monitoring in Connecticut

The 2,983 miles of streams in Connecticut support a range of uses, including drinking water, recreation, and fish and shellfish habitat. The State is required by the Clean Water Act to assess the health of these waters every two years.
