Blog: Saving endangered fish one weir at a time
Protecting and responding to threats of the Colorado River endangered fishes (Colorado pikeminnow, razorback sucker, bonytail, and humpback chub) are an important part of the Bureau of Reclamation’s mission. Threats such as fish entrainment in water diversions, have long been recognized by resource managers as a threat to native, especially endangered and threatened fish in the Colorado River Basin. Fish entrainment is the unwanted passage and loss of fish through a water intake, for example, when fish are transported with the flow of streams, creeks or rivers that are being diverted for irrigation and other uses.
