Lower Colorado River Species List

What follows are four lists of Colorado River species: native fish species, introduced fish species, endangered species, and locally extinct species (in the lower Colorado River). These species lists are by no means complete, but they are representative of the ecological condition of the lower Colorado River. Not all of the endangered and extinct species have necessarily been affected by the construction of the Glen Canyon Dam, but a great many have, either directly or indirectly.
