Federal water managers are reopening endangered species and water-sharing rules in the Klamath Basin as salmon return to newly free-flowing stretches of the river and as the Trump administration pushes agencies to maximize water deliveries. The Bureau of Reclamation formally asked federal fisheries agencies last week to help rewrite the endangered species rules that govern its dams and pumps that deliver water from the Klamath River on the California-Oregon border. … Alan Heck, the bureau’s Klamath Basin manager, told the conference attendees [Wednesday] that he expected the new guidelines to represent a “fairly large shift in the way we do business” following President Donald Trump’s executive order to maximize water supply last year.
