The National Water Dashboard (NWD) is a mobile, interactive tool that provides real-time information on water levels, weather, and flood forecasts - all in one place on a computer, smartphone, or other mobile device. The NWD presents real-time stream, lake and reservoir, precipitation, and groundwater data from more than 13,500 USGS observation stations across the country.

New US Topo maps for Alaska are being produced statewide, with digital 7.5 minute 1:25,000-scale maps providing a comprehensive update to the 15-minute 1:63,360-scale printed maps produced nearly fifty years ago. You can view a status map showing where the new maps are available, and link to a site to download the maps.

This is an interactive version of the Alaska geologic map database which allows a user to view and access many features of the database and map through a standard web browser. In other words, there is no need for or knowledge of specialized GIS software.

The portal is a searchable, web map-based tool to facilitate public and partner access to information on over 200 subjects under USGS study in the Nation's largest State.

The Marine Ecoregions layer is based upon the work of Piatt and Springer (2007). This data layer was constructed to allow researchers access to a standard map of meso-scale marine eco-regions for the waters surrounding Alaska.
