Rocky Mountain Regional Snowpack Chemistry Monitoring Study
Snowpacks collect atmospheric deposition throughout the snowfall season and offer a unique opportunity to obtain a composite sample of the chemistry of most of the annual precipitation at high elevations [> 1,800 meters]. The purpose of the snowpack network is to determine annual concentrations and depositional amounts of selected nutrients and other constituents in snow resulting from...
National Parks North Coast and Cascades Network Critical Loads
Nutrients such as nitrogen are essential for plant and animal growth and nourishment, but overabundance can cause adverse effects. Excess amounts of nitrogen from the atmosphere can cause a lake to go through eutrophication, the process in which excess nitrogen triggers a series of events that cause a lake to become fatally low in dissolved oxygen. Alpine lakes are especially sensitive to...
Spokane Valley - Rathdrum Prairie
The Spokane Valley/Rathdrum Prairie aquifer, which extends across Idaho and Washington, is the sole source of drinking water for more than 450,000 people. Recently submitted water-rights requests would substantially increase withdrawals from the aquifer. The public and state resource management agencies need an improved understanding of the SVRP hydrologic system in order to ensure appropriate...
River Loads into Puget Sound
The Issue: Puget Sound, WA, is the second largest estuary in the United States and its unique geology, climate, and nutrient-rich waters sustain biologically-productive terrestrial, coastal, and marine habitats. Development and associated human activities have significantly degraded the Sound, causing declines in fish and wildlife populations, water-quality issues, and losses...
Regional Stormwater Monitoring Program Sampling
The Issue: The State of Washington issues Municipal Stormwater Permits to local governments in the Puget Sound region that require them to develop and implement a stormwater management program that reduces the discharge of pollutants and protects the quality of water in rivers, streams, lakes and Puget Sound. The permitees in partnership with the State need to measure whether...
Coal Transport
The Issue: Federal and state natural resource managers and Tribes are concerned with the environmental impacts from unintentional release of coal dust from train cars during transport through the Northwest. Proposed new coal export terminals in Washington and Oregon would substantially increase rail traffic through the Northwest and the release of coal dust to the environment...
Quinault Groundwater
The Issue: Located on the north coast of Washington within the Queets-Quinault Watershed, the Quinault Indian Nation's coastal communities rely on groundwater as their sole source of drinking water. Climate change can directly affect groundwater throughout the watershed, particularly worrisome in vulnerable coastal aquifers. The Quinault Indian Nation will be collecting...
Riparian Ecology
Riparian ecologists in the AS Branch study interactions among flow, channel change, and vegetation along rivers across the western United States and worldwide. Our work focuses on issues relevant to the management of water and public lands, including dam operation, climate change, invasive species, and ecological restoration. Investigations take place on a range of scales. For example,...
Riparian Vegetation Response to Dam Removal
Dam removal is an approach to river restoration that is becoming increasingly common. In most cases, dam removal is driven by considerations other than river restoration like dam safety, but how dam removal affects aquatic and riparian systems is of great interest in many dam removals. My work in this area has had two areas of focus thus far: 1) studies of vegetation and geomorphic change...
Streamflow-fluvial Geomorphology-riparian Vegetation Interactions
The foundation for applying science to river and riparian restoration contexts lies in a basic understanding of the factors that drive riparian vegetation dynamics. Much of our research is focused on clarifying relationships between streamflow, fluvial geomorphology, and riparian vegetation, including various feedbacks.
Western Drought Resilience Assessment
We collected streamflow, water temperature, and other data from more than 2,500 gaging stations on rivers and streams across California, Idaho, Nevada, Oregon, Utah, and Washington to document the severity of the 2015 drought. We are using the data collected to assess how warmer winter temperatures, reduced mountain snowpack, and a shift in precipitation from snow to rain may affect future...
Mason County
The Issue: Groundwater is an important resource for domestic, commercial, and industrial usage in Mason County, and groundwater discharge helps maintain late-summer and early-fall streamflow (baseflow) in many area streams. Consequently, as the population grows, and commercial and industrial activity increase, so does the demand for groundwater. However, the quantity of usable...

The 3DEP products and services available through The National Map consist of lidar point clouds (LPC), standard digital elevation models (DEMs) at various horizontal resolutions, elevation source and associated datasets, an elevation point query service and bulk point query service. All 3DEP products are available, free of charge and without use restrictions.
Coastal and Marine Geology Video and Photography Portal
This portal contains U.S. Geological Survey (USGS) video and photography of the seafloor off of coastal California and Massachusetts, and aerial imagery of the coastline along segments of the Gulf of Mexico and mid-Atlantic coasts. These data were collected as part of several USGS Coastal and Marine Geology Program Seafloor Mapping projects and Hurricane and Extreme Storm research.
Orthoimagery Data
Orthoimagery data typically are high resolution aerial images that combine the visual attributes of an aerial photograph with the spatial accuracy and reliability of a planimetric map. The National Map offers public domain, 1-meter orthoimagery for the conterminous United States with many urban areas and other locations at 2-foot or finer resolution.
The National Map Small-Scale Collection
The National Map offers a collection of small-scale datasets, most of which are at 1:1,000,000. The National Map publishes two data collections at one million-scale: one for Global Map users and one for National Map users. In terms of vector geometry, the lines, points, and areas in these data collections are identical. The difference is in the attributes assigned to these features.
Volcano Monitoring Data
Many volcanoes in the U.S. are monitored by arrays of several instruments that detect subtle movements within the earth and changes in gas and water chemistry. The Volcano Hazards Program streams this data to its Volcano Observatories and makes it available on volcano-specific websites.
Current Alerts for U.S. Volcanoes
Volcano-alert notifications are produced by Volcano Observatory scientists based on analysis of data from monitoring networks, direct observations, and satellite sensors. They are issued for both increasing and decreasing volcanic activity and include text about the nature of the unrest or eruption and about potential or current hazards and likely outcomes.
