Powder River: Data for Cross-Channel Profiles at 22 Sites in Southeastern Montana, 1975 through 2019

Powder River rises in the Bighorn Mountains of Wyoming and flows northward through a semi-arid landscape in Wyoming and Montana to the Yellowstone River. The river drains an area of 34,700 square kilometers and has an average discharge of about 500 million cubic meters per year. Cross-channel profile data were collected at 22 sites on the river and its tributaries from 1975 through 2014.

USGS Blue Carbon Projects

Together with partner organizations, the USGS is involved in data collection, analysis, and synthesis to improve estimates of coastal wetland carbon fluxes.  This research will help improve science and data availability across a wide range of topics.

Water Quality of San Francisco Bay Research and Monitoring Project

Since 1969, the U.S. Geological Survey has maintained a research project in the San Francisco Bay-Delta system to measure and understand how estuarine systems and tidal river deltas function and change in response to hydro-climatic variability and human activities.

Transboundary Assessments of Water Quality in the Pacific Northwest

In 2019, the USGS began studying the baseline water-quality of selected transboundary rivers in the Pacific Northwest. These studies are designed to characterize current water-quality conditions so as to facilitate future assessments of potential impacts related to upstream mining activities.

Atmospheric Warming, Loss of Snow Cover, and Declining Colorado River Flow

Declining snow cover is playing a key role in decreasing the flow of the Colorado River, “the lifeblood of the Southwest,” by enabling increased evaporation. As the warming continues, increasingly severe water shortages are expected.

National Hydrologic Model Infrastructure

The USGS National Hydrologic Model (NHM) infrastructure supports the efficient construction of local-, regional-, and national-scale hydrologic models. The NHM infrastructure consists of: 1) an underlying geospatial fabric of modeling units with an associated parameter database, 2) a model input data archive, and 3) a repository of the physical model simulation code bases.

SPARROW Mappers

SPARROW mappers are interactive tools that allow the user to explore river streamflow and nutrient and sediment loads and yields and the importance of different sources of contaminants in a particular river basin. Data can be visualized using maps and interactive graphs and tables, and rankings can be shown by state, major watershed, hydrologic unit (HUC), and catchment.

New Water-Quality Directions

As the USGS Water Resources Mission Area looks to the future, we are updating our water programs to meet 21st century water-resource challenges. As part of these updates, we are integrating the National Water Quality Assessment Project's water-resource monitoring, assessment, trends, modeling, and forecasting activities into new WMA programs.

Integrated Water Availability Assessments using Cooperative Matching Funds

A group of new projects from across the U.S. will help to support development of National and Regional Integrated Water Availability Assessments (IWAAs). They will be conducted with State and local partners with the support of Cooperative Matching Funds and will focus on improving the data, tools, and information stakeholders need to make water-resource management decisions.

Harmful Algal Bloom (HAB) Cooperative Matching Funds Projects

New projects from coast to coast will advance the research on harmful algal blooms (HABs) in lakes, reservoirs and rivers. The vivid emerald-colored algal blooms are caused by cyanobacteria, which can produce cyanotoxins that threaten human health and aquatic ecosystems and can cause major economic damage.
