National Water Information System (NWIS) Mapper

The National Water Information System (NWIS) Mapper provides access to over 1.5 million sites contained in the USGS National Water Information System (NWIS), including sites where current and historical surface-water, groundwater, springs, and atmospheric data has been collected. Users can search by site type, data type, site number, or place.

Jemez Mountains Debris-Flow Map

Potential postwildfire debris-flow hazards—A prewildfire evaluation for the Jemez Mountains, north-central New Mexico, Scientific Investigations Report 2016-5101

What is a Shift-Adjusted Rating?

Stage-discharge relationships (ratings) are primarily developed from a graphical analysis of multiple streamflow measurements. Measurements are generally made on 8-week intervals. The frequency/interval of streamflow measurements may change based on a variety of circumstances including (but not limited to) flow conditions and rating definition.

Drip Calculator: How Much Water Does a Leaking Faucet Waste?

Check your faucets at home -- do any of them drip? Well, maybe it's just a small drip -- how much water can a little drip waste? True, a single drip won't waste much water, but think about each faucet in your home dripping a little bit all day long. What if every faucet in every home on your block ... in your town ... in your state also dripped?

Aquifers: Map of the Principal Aquifers of the United States

The areal and vertical location of the major aquifers is fundamental to the determination of groundwater availability for the Nation. The map, which is derived from the Ground Water Atlas of the United States, indicates the areal extent of the uppermost principal aquifers on a national scale.

USGS StreamStats

StreamStats version 4 is a Web application that provides access to an assortment of Geographic Information Systems (GIS) analytical tools that are useful for water-resources planning and management, and for engineering and design purposes. 

Annual Water Data Reports

Beginning with Water Year 2006 and ending with Water Year 2013, annual water data reports were made available as individual electronic Site Data Sheets for the entire Nation for retrieval, download, and localized printing on demand. As of 2014, NWISWeb now provides an on-demand, print-ready Water-Year Summary as an annual water-data product.

USGS Groundwater Watch

The USGS has a distributed water database that is locally managed. Surface water, groundwater, and water quality data are compiled from these local, distributed databases into a national information system. The groundwater database contains records from about 850,000 wells that have been compiled during the course of groundwater hydrology studies over the past 100 years. 

New Mexico Bureau of Geology and Mineral Resources Interactive Map (NMBGMR)

These geospatial data are provided to the public to aid in the understanding of the geologic resources of New Mexico.

The National Map

The National Map is a collaborative effort among the USGS and other Federal, State, and local partners to improve and deliver topographic information for the Nation. It has many uses ranging from recreation to scientific analysis to emergency response. The National Map is easily accessible for display on the Web, as products and services, and as downloadable data.
