Water Research

Current streamflow conditions in Alaska
Map legend.

Welcome to the U.S. Geological Survey (USGS) Web page for the water resources of Alaska; this is your direct link to all kinds of water-resource information. Here you'll find information on Alaska's rivers and streams, groundwater, water quality, and many other topics. The USGS operates the most extensive satellite network of stream-gaging stations in the state, many of which form the backbone of flood-warning systems.

The USGS provides current ("real-time") stream stage and streamflow, water-quality, and groundwater levels for over 100 sites in Alaska.

AK Monitoring Networks

The USGS Alaska Science Center Water Resources Office continuously monitors surface water, groundwater, and water quality parameters across the state. Monitoring sites are operated in cooperation with various local, State, or Federal agencies.

Streambed Scour

The USGS Alaska Science Center is researching streambed scour at bridges through scour monitoring, hydrodynamic modeling, and data collection during high flows.

Surface Water

Alaska provides real-time water-stage, streamflow and precipitation data at 152 sites across the state.


Fourteen groundwater wells are monitored by the USGS in Alaska. These wells record data on hourly intervals.

Flood Watch

The "Flood and high flow" map shows the location of streamgages where the water level is currently at or above flood stage.

Water Quality

Water-quality conditions are continuously monitored by the USGS at 43 sites across the state of Alaska
