Alaska Freshwater Fish Inventory (AFFI)
Interactive Mapping

Inventory Maps: The Fish Resource Monitor runs using the Adobe Flash Player and displays the location of sites where fish have been collected or observed. The Alaska Freshwater Fish Inventory(AFFI) data sets are provided for general reference and to aid users in generating various natural resource analyses and products. Please read the Liability Statement before beginning. The new viewer allows access to AFFI points, Fish Passage (culverts), and Anadromous Waters Catalog (AWC) data sets all in a single application.

The map incorporates sampled locations from the AFFI data set as well as USGS base maps, aerial photos, roads, communities, streams. Interactive mapping provides you the ability to create your own maps by zooming in and out to an area of interest, selecting features you would like to know more about, searching for specific areas or species, copying the map, and viewing detailed reports.
