Economics and Ecosystem Services

Federal policymakers and land managers are accountable to the public for how they invest public funds and for the outcomes of the policy and management decisions they make. Through a variety of economic analyses and custom modeling, SEA economists evaluate how investments and management decisions affect individuals, local communities, and society as a whole.

Glacial Aquifer System Groundwater Availability Study

The Glacial Aquifer System Groundwater Availability Study began in 2012 and will be completed in 2016. The glacial aquifer system groundwater availability study is one of the USGS efforts in response to the Department of Interior WaterSMART initiative. This study is designed to provide information and analysis to stakeholders and decisionmakers for characterizing groundwater availability in...

Structure maps of the Carrizo-Wilcox aquifer in northwestern Louisiana

Groundwater resources in northwestern Louisiana may be needed for development of natural gas production from the Haynesville Shale. Use of groundwater for hydro-fracturing of the shale may lower water levels and alter groundwater flow directions in the Carrizo-Wilcox aquifer and other local aquifers. Regional maps of aquifers in northwestern Louisiana are unavailable. The LaWSC, in cooperation...

Water Use Trends in Alabama

Since 1950 when the U.S. Geological Survey (USGS) first conducted water-use compilations, important changes in water use have occurred in Alabama. The early part of the history (1950 to 1980) showed a steady increase in water use. During this time, the expectation was that, as the population increased, so would water use. Contrary to this expectation, reported water withdrawals declined in...

Lower Tennessee River (LTEN) Basin Study

Welcome....the Lower Tennessee River Basin in Tennessee, Alabama, Georgia, Kentucky, and Mississippi is one of the 59 study units that are part of the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program.The long-term goals of this program are to describe the status and trends in the quality of a large, representative part of the Nation's surface- and ground-water...

Streamflow Data Available Online

The USGS in Michigan-in cooperation with local, State, Tribal, and Federal partners-operates 155 streamgages recording stage and streamflow, and 13 lake-level gages. There are about 7,400 streamgages nationwide; many of these gages provide real-time data in 15-minute increments, which typically are transmitted to the World Wide Web every 1 to 2 hours using satellite, telephone, or cellular...

Low-Flow Streamgage Network in Michigan

Data on low-flow characteristics are used by water-resources managers for a variety of purposes, including water-supply planning, making decisions about wastewater-discharge and water withdrawal permits, and evaluating in-stream flow requirements. The Michigan low-flow network currently consists of seven sites where streamflow is typically measured only during low-flow periods. In addition to...

Water-Quality Monitor Network in Michigan

The USGS operates a network of real-time water-quality monitoring stations that measure up to five physical parameters. The parameters are temperature, specific conductance, pH, dissolved oxygen, and turbidity. One to four of those parameters are measured at 26 sites, while all five parameters are measured at 13 sites. These data are used for decision making about hydroelectric power...

Crest-Stage Streamgage Network in Michigan

Historically, small streams with drainage areas less than 100 square miles have not been adequately represented in regional peak- (high) flow analysis. In Michigan, USGS operates 24 traditional crest-stage gages, where stage and streamflow is only measured during high flows, and 6 continuous-record crest-stage gages, where cooperators can continually monitor stage and USGS maintains a high-...

Connecting Channels

In response to decreasing water levels in the Great Lakes, especially Lake Michigan and Lake Huron, the International Upper Great Lakes Study (IUGLS) asked USGS to continuously measure flows in the connecting channels of St. Marys, St. Clair, and Detroit Rivers, and Water Survey Canada (WSC) to measure flows of Niagara River. To accommodate the effects of variable backwater and the...

Bacterial Pathogens

The U.S. Geological Survey (USGS) Michigan Bacteriological Research Laboratory (MI-BaRL) studies the source, occurrence, and distribution of the bacterial pathogens Shiga-toxin producing E. coli (STEC), Salmonella, Shigella, Campylobacter, Enterococcus, and Staphylococcus and the relation of occurrence of pathogens with fecal indicator bacteria, land-use, season, hydrology, geology, weather...

Avian Botulism in Distressed Great Lakes Environments

Botulism outbreaks occur within the Great Lakes and often result in significant bird die offs. It is believed that Clostridium botulinum is the reason for these die offs and the trophic pathways that this organism travels are of interest to understanding its place within the food web. The GLRI Avian Botulism Project is investigating six different matrices: sediment, Cladophora, invertebrates,...
