Damming of the Colorado, alongside introduction of game fish species, has led to an extensive decline in numbers of native fish. Scientists have found that physical changes to the river caused by damming have adverse effects on young native fish because they are unable to effectively swim away from introduced predators. They have made proposals to management agencies, which, if implemented, could help reverse the loss of native species.
