Hydrochemical Analysis of Groundwater in Jewel Cave National Monument

The Issue: The park’s landscape and geomorphology is characterized as a carbonate karst environment, with sinking streams and fast connections between surface water and groundwater, resulting in high vulnerability of contamination to groundwater. Now that subterranean lakes have been discovered in Jewel Cave, understanding the groundwater connection of the lakes therein to the...

Effects of Short Chain Chlorinated Paraffins (SCCPs) on developing birds

The Challenge: Short-Chain Chlorinated Paraffins (SCCPs) are complex technical mixtures of polychlorinated n-alkanes used in lubricants and coolants in metalworking, as flame retardants, and in paints, adhesives, sealants, textiles and polymeric materials, plastics and rubber. SCCPs are of concern because they are globally transported, bioaccumulate in wildlife and humans, and are...

Grand River near Painesville, 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....

Invasive Phragmites Science: Management Tools for the Control of Invasive Phragmites to Foster the Restoration of the Great Lakes

The USGS is developing innovative Phragmites control measures to keep this rapidly spreading invasive plant from further expanding its range into new wetland habitats and to aid in the development of successful restoration strategies. Scientists are conducting studies and field tests to determine if fungi that live within the Phragmites are enabling the plant to take over...

Aquatic Native Species and Habitat Restoration: Custodial Maintenance of Fish Spawning Reefs

To ensure the long-term viability and function of constructed fish spawning reefs in the St. Clair-Detroit River System (SCDRS), periodic maintenance and repair of the reefs are required. To remove sediment from reefs, researchers developed a portable pressurized water jet that can be deployed by a small vessel. Reef cleaning experiments were conducted during late summer and fall of 2018, with...

Foundations for Future Restoration Actions: Cooperative Science and Monitoring Initiative - Lake Ontario, 2018

Environmental organizations from the United States and Canada have teamed up each year, as part of the Cooperative Science and Monitoring Initiative (CSMI) program, to assess conditions in one of the five Great Lakes. . Each year, the survey focuses on a series of research areas, such as phosphorus and nitrogen input and movement through the food web, phytoplankton and zooplankton populations...

Urban Best Management Practices: Reporting Reductions of Untreated Urban Runoff as a Result of GLRI-funded Urban BMPs

The objectives of this project are to quantify reductions in the volume of urban stormwater runoff through implementation of green infrastructure practices, model stormwater characteristics to further explore our understanding of the hydrologic functions performed by green infrastructure and assess how green infrastructure may help or hinder sequestration of chloride from application of...

Aquatic Native Species and Habitat Restoration: Cisco Spawning Habitat Assessment

Cisco (formerly known as Lake Herring) Coregonus artedi are native shallow water coregonines which were formerly very abundant in the Great Lakes and provided large commercial fisheries and healthy prey to native piscivores.  In most areas outside of Lake Superior, cisco abundance is greatly reduced and in Lakes Ontario and Erie they are uncommon to rare.

Agriculture Best Management Practices: Quantification of In-Stream Phosphorus and Sediment Storage and Transport - Linking Land Use and Landscape Best Management Practices with Downstream Transport in Great Lakes Restoration Initiative Priority Watersheds

As part of a coordinated effort with University of Minnesota (UMN) and US Forest Service (USFS), USGS will conduct sediment and phosphorus source tracking in two agricultural watersheds -- specifically corn and soybean production -- of Black Creek and Plum Creek, tributaries to the Maumee and Fox Rivers, respectively.

Past Perspectives of Water in the West

In the intermountain west, seasonal precipitation extremes, combined with population growth, are creating new challenges for the management of water resources, ecosystems, and geologic hazards. This research contributes a comprehensive long-term context for a deeper understanding of past hydrologic variability, including the magnitude and frequency of drought and flood extremes and ecosystem...
