USGS Responds to Spring Flooding
U.S. Geological Survey field crews are measuring flooding across the country as spring weather is in full swing. Warming temperatures, increased precipitation and snowmelt have caused moderate to major flooding in the upper Midwest, East Coast, Central Plains and the Southeast portions of the country.
Flights Above the Mississippi Alluvial Plain to Continue Aquifer Mapping
New Phase of USGS Low-level Surveys Begins in November
POSTPONED due to weather: Ask Questions and Learn More About the Low-Level Helicopter Flying Above the Mississippi Alluvial Plain
Media: Please join the U.S. Geological Survey, CGG Airborne and various partners for a demonstration of the low-flying helicopter and description of what scientists are seeking in and around the Mississippi Alluvial Plain.

Estimating the effect of winter cover crops on nitrogen leaching using cost-share enrollment data, satellite remote sensing, and Soil and Water Assessment Tool (SWAT) modeling
This study employed a novel combination of data (winter cover crop cost-share enrollment records, satellite remote sensing of wintertime vegetation, and results of Soil and Water Assessment Tool (SWAT) water quality simulations) to estimate the environmental performance of winter cover crops (WCC) at the watershed scale, from 2008 through 2017,...

Species richness responses to water withdrawal scenarios and minimum flow levels: Evaluating presumptive standards in the Tennessee and Cumberland River basins
Water resource managers are challenged to balance growing water demand with protecting aquatic ecosystems and biodiversity. Management decisions can benefit from improved understanding of water withdrawal impacts on hydrologic regimes and ecological assemblages. This study used Ecological Limit Functions for fish groups within the Tennessee and...

Magnitude and frequency of floods in Alabama, 2015
To improve flood-frequency estimates at rural streams in Alabama, annual exceedance probability flows at gaged locations and regional regression equations used to estimate annual exceedance probability flows at ungaged locations were developed by using current geospatial data, new analytical methods, and annual peak-flow data through September...
