METHODS
Study Area
The study area encompassed ponds along the Colorado River from Rifle to the
Colorado/Utah state line and along the Gunnison River from Austin to the confluence
with the Colorado River (Figure 1). Ponds of special interest were those located within
the 50-year floodplain; however, ponds outside this floodplain that were potential
sources of nonnative fish entering critical habitat, were also subject to control.
Figure 1. The nonnative fish control study area encompassed ponds along the Colorado
River from Rifle, CO (RM 241) to the Colorado/Utah state line (RM 132) and along the
Gunnison River from Austin, CO (RM 60) to its confluence (RM 0) with the Colorado
River (RM 171).
