Midwest stream through row crop
June 2, 2013

Midwest streams flow through intensive row cropping

In the Corn Belt states of the Midwestern U.S., intensive row-cropping surrounds small streams, effectively eliminating riparian cover and habitat. Agricultural activities can have profound effects on the chemical and physical characteristics of small streams. In 2013, the USGS Regional Stream Quality Assessment (RSQA)

CAFOs in Midwest a source of nitrogen

Many small farms in the Corn Belt state of the Midwest also have confined animal feeding operations (CAFOs). These CAFOs can be a source of nitrogen to receiving small streams. The USGS Regional Stream Quality Assessment (RSQA) investigated the water quality of small streams across the Midwest during 2013.

Installing a microsampler in a flooded creek

Installing a microsampler for daily collection of pesticides

A USGS hydrologist and hydrologic technician install a microsampler in an urban creek in Milwaukee, Wisconsin. The microsampler allows collection of a sample "sip" every 6 hours; the sips are composited into a daily sample. Collection of daily samples revealed the presence of more pesticides and higher concentrations than manual samples collected weekly. See

Installing a micro water-quality sampler in high water

Micro-samplers are sophisticated instruments that collect small "sips" of water at designated intervals.  Installing one during high water conditions is a tricky business.  The samples, collected every few hours, provide a picture of how rapidly water quality can change over time.  These samples were analyzed for a suite of hundreds of pesticides.  In 2013, the USGS

micro-sampler collects "sips" of water for pesticide time-series

Micro-samplers are sophisticated instruments that collect small "sips" of water at frequent intervals.  The samples, collected every few hours, provide a picture of how rapidly water quality can change over time.  These samples were analyzed for a suite of hundreds of pesticides.  In 2013, the USGS Regional Stream Quality Assessment (

Ohio Nowcast

As schools close for the year and summer weather beckons, many recreationalists head to the Great Lakes' public beaches. However, these coastal areas can become contaminated with disease-causing bacteria that threaten public health, disrupt water recreation, and pay a toll on the Great Lakes economies that depend on summer tourism.

Water-Level Fluctuations at Sheboygan River Mouth, Sheboygan, WI

A series of time-lapse photographs capture rapid water-level fluctuations in the vicinity of Wildwood Islands in the Sheboygan River, 4.4 km upstream of Lake Michigan near Sheboygan, Wis. The fluctuations are caused the interaction of seiche-related oscillations from Lake Michigan with river flows.
