This web page displays groundwater-level data for selected wells monitored by the U.S. Geological Survey (USGS) in and near the Duwamish River valley, King County, Washington. These data are part of a project to better understand the geology and groundwater in and near the Duwamish River valley and how groundwater may contribute to flooding in the valley.

The Central Valley has four hydrologic regions, from north to south: the Sacramento Valley, the Delta & Eastside Streams, the San Joaquin Basin, and the Tulare Basin. Water flows from Sacramento Valley, Tulare Basin, and the San Joaquin Basin, into the Delta & Eastside Streams through the Central Valley's only natural outlet, the Carquinez Strait, on its way to the Pacific Ocean.

The Invasive Carp Open Data Hub is a platform for exploring and accessing USGS data, tools, applications, and publications related to invasive carp research and management.

Annual Joint Agency Commercial Imagery Evaluation (JACIE) workshops engage federal agencies, their partners, and the commercial remote sensing industry to understand the characteristics and capabilities of current and new data sources, along with the quality of data they provide. This tool allows the searching of presentations from the workshops, that started in 2001.

This ArcGIS Online Dashboard provides an interactive platform to view drilling waste land application data in Oklahoma.

How does your state use Landsat satellite data? Find out here! For each state, you can download a satellite image, put together an online puzzle, or read a USGS Fact Sheet that contains information about the benefits of Landsat.

Do you need to know when streamflows are low or if streams go dry? The USGS has developed a Low Flow Data and Model Discovery Table that provides an overview of available data and models with information on streamflow, including low-flow and no-flow conditions.

The National Water Availability Assessment Data Companion (NWDC) delivers model-based estimates of water supply and demand.

USGS, in cooperation with the Pennsylvania Department of Environmental Protection (PaDEP), has released a geonarrative detailing the sampling of a network of surface water sites across Pennsylvania.

The USGS Real-Time Flood Impact Map helps communities stay safe by providing real-time information and visuals about locations in their area that may be experiencing flooding.

Identifying areas expected to remain buffered from climate change and maintain biodiversity and ecological function is important for climate adaptation planning. As structurally diverse transitional zones between terrestrial and aquatic environments, riparian areas are often biological hotspots and provide critical corridors for species movement, particularly in arid and semi-arid regions.

Streams, rivers, lakes and reservoirs are important natural resources for irrigation, public supply, wetlands and wildlife. Excess precipitation that flows into these sources is called runoff, and it's an important drought indicator. The California Water Science Center tracks both monthly and annual runoff.
