Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted.  For more information, please see www.doi.gov/shutdown

Office of the Delaware River Master

In 1954, the U.S. Supreme Court issued a Decree in State of New Jersey v. State of New York and City of New York in which the Court designated the position of the Delaware River Master.  The Court directed that the River Master perform multiple duties and functions in administering the Decree, including the conserving the waters of the river and the Delaware River watershed; compiling data on...

Next Generation Water Observing System: Delaware River Basin

The USGS next-generation water observing system will provide high-fidelity, real-time data on water quantity and quality necessary to support modern water prediction and decision support systems for water emergencies and daily water operations. The Delaware River Basin pilot provides an opportunity to develop the NextGen observing system in a nationally important, complex interstate river...

Flood Inundation Mapping Science

When planning for a flood, there are three key questions that must be answered: What areas will be flooded? How deep will the flood waters get? When will the flood arrive? Historical flooding can help a community anticipate how much impact similar flood events could have, but there are other methods and tools that can provide more accurate and nuanced estimations of a wide variety of...

Flood Inundation Map (FIM) Libraries

The Flood Inundation Mapping Program focuses on developing flood inundation map libraries and helping communities pair those libraries with real-time stream data and National Weather Service flood forecasts to form a two-dimensional flood warning system. Together, these products can help communities estimate the extent of a flood and identify at-risk areas and resources in advance of...

Emerging Flood Inundation Mapping Technologies

The following technologies represent state-of-the-art tools, methodologies, and techniques that the USGS and our partners are researching and testing. Most of these techniques are experimental and not publicly available, but could significantly improve our ability to plan for and respond to flooding events in the future.

Flood Inundation Mapping - Loss Estimation

Using a flood inundation map library to estimate where floodwaters will go and how deep they will be is crucial for planning and preparing for floods. By performing loss-estimation modeling, the potential physical, economic, and social impacts of disasters can be calculated, helping communities anticipate the effects of flooding and identify specific strategies to reduce losses and speed...

Flood Inundation Mapping (FIM) Program

Floods are the leading cause of natural-disaster losses in the U.S. More than 75 percent of declared Federal disasters are related to floods, and annual flood losses average almost $8 billion with over 90 fatalities per year. Although the amount of fatalities has declined due to improved early warning systems, economic losses continue to rise with increased urbanization in flood-hazard areas...

StreamStats

StreamStats provides access to spatial analytical tools that are useful for water-resources planning and management, and for engineering and design purposes. The map-based user interface can be used to delineate drainage areas, get basin characteristics and estimates of flow statistics, and more. Available information varies from state to state.

Spectral Gamma Borehole Logging

Spectral gamma borehole geophysical methods measure natural-gamma energy spectra, which are caused by the decay of uranium, thorium, potassium-40, and anthropogenic radioactive isotopes. Spectral gamma data can be used to identify and quantify the amount of uranium, thorium, and potassium-40 isotopes detected in boreholes.

Water Chemistry Data for Selected Springs, Geysers, and Streams in Yellowstone National Park, Wyoming, Beginning 2009

Results of water analyses conducted on numerous thermal and non-thermal features in Yellowstone National Park beginning in 2009. Water samples were collected and analyzed as part of research investigations on arsenic, iron, nitrogen, and sulfur redox species in hot springs and overflow drainages; the occurrence and distribution of dissolved mercury; and general hydrogeochemistry of hot springs...
