NWISWeb: New Site for the Nation's Water Data
NWISWeb Data for the Nation
Data Category
Current - conditions data transmitted from selected
surface- water, ground - water, and water - quality sites.
Descriptive site information for all sites with links to all
available water data for individual sites.
Water flow and levels in streams, lakes, and springs.
Water levels in wells.
Introduction
These pages provide access to water - resources data collected at approximately
1.5 million sites in all 50 States, the District of Columbia, and Puerto Rico. Online
access to this data is organized around categories listed to the left.
The USGS investigates the occurrence, quantity, quality, distribution, and
movement of surface and underground waters and disseminates the data to the
public, State and local governments, public and private utilities, and other Federal
agencies involved with managing our water resources.

Introduction
The online National Water Informa-
tion System (NWISWeb) provides the
public with access to more than 100 years
of water data collected by the U. S. Geo-
logical Survey (USGS). The new Web site
( http: / /waterdata.usgs.gov /nwis/) allows
users to access several hundred million
pieces of historical and real -time data —all
from home or office computers.
"We keep up with the stage and
flow on a daily basis."

Data integration
USGS has been providing real -time
and historic streamflow data on the Web
since 1994. However, the information
was available for each State only through
separate Web sites. The NWISWeb
system improves that service by aggre-
gating all the data into one national
database accessible through one Web site.
NWISWeb integrates stream -flow infor-
mation with many other types of water
data, including historic water - quality data
from rivers and aquifers, historic ground-

provide."
Mission
NWISWeb is an integral part of the
USGS mission to disseminate important
water - quality and quantity data to the
public. These data can help interested
parties, such as water managers, engi-
neers, scientists, emergency managers,
recreational water users, utilities, and
others, to:
♦ Evaluate current water supplies and
plan for future supplies.
4 Forecast floods and droughts.
♦ Operate reservoirs for hydropower,
flood control, or water supplies.
♦ Evaluate and control water quality.
♦ Navigate rivers and streams.
♦ Safely and enjoyably fish, canoe,
kayak, or raft.
♦ Study how the Nation's water
resources are changing over time.
