The fish ladder near the Price-Stubb Diversion Dam is finished. The $10.2 million fish ladder is submerged when Colorado River waters run high. The ladder’s large basalt boulders on the Colorado River’s left bank and rock ramp built along the downside face of the dam will become more visible when waters recede. The ladder helps four native, endangered fish species — the razorback sucker, Colorado pikeminnow, humpback chub and bonytail chub — over the dam from which the ladder takes its name. The fish climb up the ladder and over the dam to migrate in the Colorado River between Lake Powell and the Rifle area. This is critical habitat for the fish, said Brent Uilenberg, technical services division manager with the U.S. Bureau of Reclamation. Employees at the bureau’s Grand Junction office designed and constructed the ladder.
