For the first time in more than a century, salmon will have free passage along the more than 400 miles of the Klamath River and its tributaries as the largest dam removal project in U.S. history nears completion along the California-Oregon border.

For the first time in more than a century, salmon will soon have free passage along the Klamath River and its tributaries — a major watershed near the California-Oregon border — as the largest dam removal project in U.S. history nears completion.

Crews will use excavators this week to breach rock dams that have been diverting water upstream of two dams that were already almost completely removed, Iron Gate and Copco No. 1. The work will allow the river to flow freely in its historic channel, giving salmon a passageway to key swaths of habitat just in time for the fall Chinook, or king salmon, spawning season.

    Aren’t there specific “Fish runs” and “Salmon runs” purposefully built to help fish migrate upstream ? Seems strange that ecological man-made structures would have been completely neglected during the entirety of the construction and management of the river(s).
