Navajo, Animas, La Plata, and Mancos Rivers in
Colorado and New Mexico, and McElmo Creek,
Recapture Creek, Montezuma Creek, and Chinlee Wash
in Utah.

Research Need: The historic and current fish community of the
tributaries to the San Juan is poorly documented.
No tributary has been systematically inventoried to
accurately define species present, their
longitudinal distribution, or relative abundance.
Knowledge of the faunal composition of the
tributaries is important to understanding their
interaction with the mainstem river and their
relationship to the basin.

(

Methods: Streams will be sampled at three to five km
intervals from their confluence with the San Juan
upstream to reaches which do not support fish or
sustain only salmonids. Where possible historic
collection sites will be sampled. Collection
techniques will include any combination of
electrofishing, trammel nets, gill nets, seines or
other sampling technique. The field work will be
conducted over a two year period (1991-1993).
