Other Studies Done Concurrently with the CRFP

Studies of ecology of the endangered fishes in the upper basin were also
conducted by biologists with the Colorado Division of Wildlife (eODOW) and
Utah Division of Wildlife (UTDWR) from the early 1980s to present (~.g.,
Haynes and Muth 1982, Radant 1982, 1986; Wick et~. 1985). This work,
funded through Section 6 of the ESA and by the states, has provided much of
the basic information used to make decisions on efforts in behalf of the rare
fishes. Studies by CODOW documented the importance of the Yampa River to the
Colorado squawfish. The importance of the Green River to squawfish and
humpback chuck was verified by UTDWR. Distribution of endangered Colorado
River fishes in Cataract Canyon was examined by private contractors with USBR
support (Valdez 1990).
Culture and propagation techniques for rare Colorado River fishes were
developed at Willow Beach (Arizona) and Dexter (New Mexico) National Fish
Hatcheries (Hamman 1982a, et ~.; lnslee 1982 a,b). And, descriptions of
