Site Assessment and Monitoring of Constructed Wetlands in Montana
The Montana Department of Transportation (MDT) occasionally causes disturbance to wetlands during construction. To comply with Federal, State, and Tribal regulations, MDT creates replacement wetlands to compensate for wetland loss. The U.S. Geological Survey (USGS) collaborates with MDT to assess potential wetland replacement sites and monitor water conditions at established replacement sites...
Monitoring Changes in Groundwater Quality at Jackson Hole Airport
USGS studies revealed that aircraft deicing fluids from Jackson Hole Airport negatively affected the water quality of the Snake River aquifer in northwestern Wyoming (Wright, 2013). In response, the airport implemented improved deicing management and infrastructure. A recent USGS study determined that the airport’s changes likely contributed to improvements in aquifer groundwater quality (Wright...
Wyoming StreamStats
StreamStats is a digital, map-based tool designed to provide information about streamflow and the upstream watershed of any selected point on a stream. The tool can assist in water resources planning and management and support engineering and design projects. In Wyoming, the current capabilities of the application are basin delineations and basin-characteristics.
Wyoming Landscape Conservation Initiative: Water Resources
The Wyoming Landscape Conservation Initiative is a long-term science-based effort to assess and enhance aquatic and terrestrial habitats at a landscape scale in southwest Wyoming, while facilitating responsible development through local collaboration and partnerships. The WLCI is an interagency working group of partners that is beginning the process of establishing a much larger coalition of...
Monitoring for Pesticides in Wyoming's Water
Wyoming's groundwater and streams are routinely monitored for pesticides. In order to balance the use of pesticides (herbicides, insecticides, and fungicides) with the protection of water resources, the Wyoming Department of Agriculture began a project to sample groundwater in 1995, in cooperation with the U.S. Geological Survey. Since the project's inception, more than 750 samples from...
WLCI: Long-term streamflow, water-quality, and groundwater data collection
Riparian and aquatic ecosystems in semiarid landscapes like Southwest Wyoming contribute substantially to regional biodiversity. Long-term monitoring data that describe streamflow, surface-water quality, and groundwater levels are needed for assessing possible effects of changes in land use on those ecosystems.
Flaxville Aquifer
The Flaxville aquifer is present in the northern and central parts of the Fort Peck Indian Reservation and consists of sand and gravel that forms extensive plateaus and topographic benches used for dryland farming. Because many residents rely on groundwater as their primary water supply on the Reservation, the Flaxville and underlying aquifers are important sources of groundwater. The goal of this...

Brine Contamination to Plains and Potholes Environments from Energy Development in the Williston Basin
Establishment of a baseline groundwater monitoring program in an area identified for energy development on the Blackfeet Reservation, Montana
As a result of energy development, the Blackfeet Environmental Office has developed a groundwater monitoring program specifically focused on the Cut Bank Creek watershed of the Blackfeet Indian Reservation. The addition of groundwater data to an existing surface-water monitoring program will help the Blackfeet Tribe develop a more complete understanding of the current conditions of their water...
Delineation of Brine Contamination in and near the East Poplar Oil Field, Fort Peck Indian Reservation, Northeastern Montana
Brine is a byproduct of crude oil production. Handling and disposal of brine during the last 50 years in the East Poplar oil field has resulted in contamination of not only the shallow Quaternary aquifers, but also the Poplar River. Previous investigations have documented and partially delineated the extent of brine contamination in the East Poplar oil field during the early 1990s. In the 10 years...
Williston and Powder River Basins Groundwater Availability Study
The development of two nationally important energy-producing areas, the Williston structural basin (containing the Bakken Formation) and Powder River structural basin, provide a critical opportunity to study the water-energy nexus within a groundwater context. Large volumes of water are needed for energy development in these basins. The hydraulically connected aquifers in the regional glacial...
Hydrologic Assessment with an Emphasis on Water Quality within the Lame Deer Creek Watershed, Northern Cheyenne Indian Reservation, Montana
The Lame Deer Creek watershed of the Northern Cheyenne Reservation in southeastern Montana encompasses about 82 square miles and is home to the community of Lame Deer. Local water resources within the Lame Deer Creek watershed include Lame Deer Creek and groundwater within unconsolidated sediments and bedrock aquifers. In 2017 the U.S. Geological Survey, in cooperation with the Northern Cheyenne...
