A popular federal effort to protect threatened Western fish is in murky waters as stakeholders await Congressional action on reauthorization.  The Upper Colorado River Endangered Fish Recovery Program has for 30 years sought to restore four species that once thrived in the river: the razorback sucker, Colorado pikeminnow, bonytail and humpback chub. A sister effort, the San Juan River Basin Recovery Implementation Program, works to restore the same fish in the Four Corners region. The species are imperiled by human-wrought habitat disruption, like dams, and preyed upon and out-competed by introduced species like rainbow and brown trout.
