Water and endangered fish in the Klamath River basin revisited: Does old age or Upper Klamath Lake surface elevation and water quality affect adult Lost River Sucker and Shortnose Sucker survival? A response to Kann and Walker

October 27, 2026

Our update responds to recent scientific critiques and again finds no evidence that lake levels or water conditions influence adult sucker survival. This reaffirms our prior work (Krause et al., 2022) and suggests that recent declines in adult survival may reflect an aging population.
