All these dams on the Klamath river did have fish ladders where the salmon could go upstream and spawn. Removing the dams just increased the number of fish swimming upstream. Some of the fish ladders had glass walls and people could watch the fish going up & down the ladder.

This is factually incorrect.

From the 2013 department of the interior report discussing dam removal "Klamath Dam Removal Overview Report for the Secretary of the Interior: An assessment of science and technical information":

> In particular, the Klamath Tribes of the upper basin have experienced their 92nd year (period starting with initial dam construction) without access to salmon and have continued to limit their harvest of suckers to only ceremonial use for the 25th consecutive year because of exceptionally low numbers and ESA protection.

I don't think that's accurate. The remaining dams have ladders, but the lowermost dams had no (or inadequate) ladders, hence the total absence of salmon from the upper Klamath.

> Although the Bureau of Reclamation’s Link River Dam and PacifiCorp’s Keno Dam currently have fish ladders that will pass anadromous fish, none of PacifiCorp’s Four Facilities (i.e., Iron Gate, Copco 1, Copco 2, and J.C Boyle dams and associated structures) were constructed with adequate fish ladders and, as a result, anadromous fish have been blocked from accessing the upper reaches of the Klamath Basin for close to a century.

N.B. Keno and Link River are _not_ being removed.

This is completely incorrect.
