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...
Characterization and Quantification of Salinity Loads from Blacks Fork above Smiths Fork near Lyman, Wyoming
The Blacks Fork is a stream that contributes a salinity load to the Colorado River Basin. In order to quantify the salinity load, collection of continuous streamflow and specific conductance data, and monthly sampling for total-dissolved solids will occur from April 2018 through September 2019. Calculations of monthly and annual salinity loading from the Blacks Fork were published in 2021.
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.

Wyoming-Montana Stream Water-Quality Network - Water Year 2020
The USGS monitors stream water quality in Wyoming and Montana in cooperation with State, County, local, and other Federal agencies. Water-quality data for these sites are available from the USGS National Water Information System Web Mapper application in the form of an interactive map that can be accessed from the Data and Tools tab.
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...
Wyoming-Montana Stream Water-Quality Network
The USGS monitors stream water quality in Wyoming and Montana in cooperation with State, County, local, and other Federal agencies. Water-quality data for these sites are available from the USGS National Water Information System Web Mapper application in the form of an interactive map.
Groundwater Quality Research
Every day, millions of gallons of groundwater are pumped to supply drinking water for about 140 million people, almost one-half of the Nation’s population. Learn about the quality and availability of groundwater for drinking, where and why groundwater quality is degraded, and where groundwater quality is changing.
