Real-time streamflow
Where is the USGS collecting and transmitting real-time streamflow data right now? How does flow today compare with historical streamflow? How can I see these sites on a map and get to the data? (Fact Sheet)
Real-time flood data

Where in the Nation are floods or very high flows occurring now? How can I see these sites on a map and get to the data?
Real-time drought data
Where in the Nation are droughts or very low flows occurring now? How can I see these sites on a map and get to the data?
Real-time ground-water levels

Where is the USGS collecting and transmitting real-time ground-water levels right now? How do levels today compare with historical levels? How can I see these sites on a map and get to the data?
Recent ground-water levels
Where in the Nation is the USGS currently collecting ground-water level data? How can I see these sites on a map and get to the data? Data shown on these maps may be as recent as a few minutes old or may be from as long as a year ago.
Ground-water response to climate
Where are the wells that are highly sensitive to climate variations where the USGS is currently collecting ground-water level data? What are the long-term and short-term trends in water levels? How can I see these sites on a map and get to the data? (Fact Sheet)
Real-time surface water quality
Where is the USGS collecting and transmitting real-time water quality data? How do levels today compare with historical levels? These data are limited to measurable characteristics such as temperature, turbidity, specific conductance (salinity), dissolved oxygen and pH (acidity). How can I see these sites on a map and get to the data?
Recreation
I want to find streamflow or water-level data that will tell me if a particular river will be suitable for rafting, kayaking, or fishing today. Some recreation links leave the USGS web sites.
USGS has a general information page at recreation.usgs.gov
Private organizations such as American Whitewater provide alternative resources that use USGS and other information for planning water-based activities. |
Annual water data reports
Can I see all of the locations where the USGS has published water resources data for a particular year? How can I see these sites on a map and get to the data?
You can retrieve data using a map or a search form.
Instantaneous streamflow data
I want to find long-term streamflow data reported in short time intervals (such as 15 minutes or 1 hour) rather than as daily averages. Where can I see a list of those sites and get to the data?
National Water Quality Assessment
![Click here to go to the NAWQA Network Click here to go to the NAWQA Network](images/nawqa160.jpg)
The NAWQA program provides a search to physical, chemical, sediment, and biological data that have been collected as part of the national program, including some aquatic ecological data that can not be stored in NWIS. (Fact Sheet)
Water use in the United States
Use of water in the United States is tracked by USGS in cooperation with state, tribal, and local governments.
Some notable collections of USGS water data
![Click to go to the sediment data collection. Click to go to the sediment data collection.](images/sediment160.jpg)
Sediment data collected by USGS is stored in NWIS and is also described in a dedicated web page and report.
![Click to go to the Hydro-Climatic Data Network collection. Click to go to the Hydro-Climatic Data Network collection.](images/hcdn160.jpg)
The Hydro-Climatic Data Network provides streamflow data between 1874 and 1988 and is useful in studying climate change.

The National Stream Quality Accounting Network provides ongoing characterization of the concentrations and transport of sediment and chemicals in the Nation's largest rivers.

USGS is the lead federal agency for monitoring of acid rain and related issues as part of the National Atmospheric Deposition Program.

The Ground-Water Atlas and
National Atlas provide many maps that summarize water resources data and related information.
