Restoring Fish Passage in Alaska

High tides bring migrating salmon through a newly restored channel to Klawock Lagoon, thanks to a Nature Conservancy–led project to install a specially designed culvert that brings tidal flows through the lagoon’s north channel once again.

At Klawock Lagoon, scientists are monitoring how a restored fish corridor is improving habitat.

Scientists use a seine net to collect fish samples.

Klawock Lagoon offers habitat for wild salmon and a range of forage fish species, such as shiner perch.
