Redfield Canyon Barrier Site

Redfield Canyon Redfield Canyon Fish Barrier Site Redfield Canyon

The Redfield Canyon fish barrier is intended to prevent upstream movements of nonnative fishes from the San Pedro River to upper Redfield Canyon that is inhabited by the endangered Gila chub. In addition, other federally-listed species including Gila topminnow, spikedace, and loach minnow have recently been repatriated to the stream above the planned fish barrier site. Construction of the Redrock Canyon fish barrier is anticipated for autumn 2012 or spring 2013.
