Legal Definitions - United States Geological Survey

The United States Geological Survey (USGS) is a department within the U.S. Department of the Interior. Its main responsibility is to create and publish maps, technical reports, and fact sheets. The USGS also collects and analyzes information about energy and mineral resources, as well as the quality and use of the nation's water resources.

For example, the USGS might create a map of a national park, showing the location of trails, campsites, and other features. They might also publish a report on the amount of oil or natural gas reserves in a particular region. Additionally, the USGS might collect data on the levels of pollutants in a river or lake, and use that information to make recommendations for improving water quality.

The USGS plays an important role in helping us understand and manage our natural resources. By providing accurate and up-to-date information, they help us make informed decisions about how to use and protect our environment.
