CASCaDE: Computational Assessments of Scenarios of Change for the Delta Ecosystem

The Delta of the Sacramento and San Joaquin rivers provides drinking water supplies to two-thirds of Californians, and is a fragile ecosystem home to threatened and endangered species. The CASCaDE project builds on several decades of USGS science to address the goals of achieving water supply reliability and restoring the ecosystems in the Bay-Delta system.

Integrated Water Science (IWS) Basins

The U.S. Geological Survey is integrating its water science programs to better address the Nation’s greatest water resource challenges. At the heart of this effort are plans to intensively study at least 10 Integrated Water Science (IWS) basins — medium-sized watersheds (10,000-20,000 square miles) and underlying aquifers — over the next decade. The IWS basins will represent a wide range of...

Integrated Water Availability Assessments: Delaware River Basin

Integrated Water Availability Assessments examine water supply, use, and availability. In the Delaware River Basin, which serves over 13 million people, water availability can be affected by drought, river temperature, salinity, and more. The Delaware River Basin IWAAs will investigate these and other water quantity, quality, and use issues to assess available water and how it changes over time.

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.

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.

Urban Waters Federal Partnership Cooperative Matching Funds Projects

The Urban Waters Federal Partnership reconnects urban communities with their waterways by improving coordination among federal agencies, particularly those communities that have been disproportionately impacted by pollution or economic distress. The UWFP draws upon Environmental Justice principles—the idea that all people, regardless of race, religion, national origin, or economic station, deserve...

Water Use in the United States

The USGS works in cooperation with local, State, and Federal agencies to collect water-use information, then compiles these data to produce water-use information aggregated at the county, state, and national levels. Every five years, data at the county level are compiled into a national water-use data system and State-level data are published in a national circular, Estimated Use of Water in the...
