The Biden administration on Wednesday announced nearly $200 million in federal infrastructure grants to upgrade tunnels that carry streams beneath roads but can be deadly to fish that get stuck trying to pass through. Many of these narrow passages known as culverts, often made from metal or concrete, were built in the 1950s and are blamed in part for declining populations of salmon and other fish that live in the ocean but return to freshwater streams to spawn. By extension, fisheries — including tribal-run operations in the Pacific Northwest — have experienced losses they blame in part on such barriers as culverts and dams. … While the most funding went to Washington and Alaska, Maine was next with $35 million. Other Western states to receive money are California, Oregon and Idaho.
