Cataloging Prince of Wales Anadromous Water Bodies

From 2019 through 2022, this project surveyed 1,336 streams and submitted 511 nominations to the Anadromous Waters Catalog, adding 77.48 miles of stream, designating 42.42 acres of floodplains and wetlands as anadromous polygons, correcting 40.16 miles of inaccurately mapped stream channels, and removing 1.95 miles of stream that were inaccurately mapped.

This project will add water bodies to the AWC, providing statutory protection to important salmon streams. The AWC is the State of Alaska’s tool to identify, protect, and manage salmon and steelhead spawning, incubation, rearing, overwintering, and migration habitats. This tool is used during fish habitat permitting to prevent, minimize, and mitigate human-induced perturbations.
