Description

Fish Species of the Colorado River in Lower Glen Canyon and Grand Canyon (See Fish Table)	TBD (TBD)	TBD (TBD)

No Ad-Hoc Group currently assigned

POTENTIAL THREATS:
Smallmouth Bass -- In early 2000, smallmouth bass increased dramatically in abundance in the Yampa River and Upper Colorado River. Just over a decade later, the species cannot be brought under control.
"Prior to Glen Canyon Dam, the Colorado River was dominated by highly predacious non-native channel catfish. Catfish are warm water fish...Regular flooding of the LCR may be keeping catfish out of the LCR and cold water in the Colrado River does not provide habitat for catfish or other warm water fish. Without Glen Canyon Dam chubs may have been extirpated from Grand Canyon, catfish would still be the dominant fish in the Colorado River and the LCR." (090711_Minority Report to TWG_FFF_Mark Steffen)
Should a disaster such as a landslide cut off the Little Colorado chub from the mainstem, the species could quickly become extinct -Article LINK
