We documented four razorback sucker (Xyrauchen texanus) individuals originally stocked in the San Juan River, New Mexico, subsequently recaptured in the Colorado and Green rivers, Utah. Each fish moved >550 km between stocking and recapture locations. The time between detections was 171–1,519 days. These movements included ≥210 km through Lake Powell. Lake Powell was previously thought to be a barrier between razorback sucker populations in the San Juan River and the Colorado and Green rivers.
