Alaska’s Watershed Prioritization Map

(Preview Only - Limited Functionality)

Please note it may take a moment for the map to load.

This map was created by the Alaska Department of Environmental Conservation in partnership with the Alaska Clean Water Actions committee to provide a statewide data-driven, objective methodology for evaluating and prioritizing watersheds for the ACWA program. The map displays information collected from a variety of publicly available GIS datasets and can be used to inform watershed issues and potential projects.

Zoom in and click on a dot to learn about the prioritization ranking for that watershed. Click on the Legend icon to the upper left to view the legend or expand the fields below for the prioritization ranking key and prioritization matrix that lists the number of watersheds in each ranking category.
