General Description

The Cochiti reach extends from the Otowi river flow gauge at the edge of the watershed to the Angostura Diversion Dam situated near the confluence of the Jemez River and the Rio Grande. The reach derives its name from the Cochiti Dam that just above the confluence of the Rio Grande and Santa Fe River. Pueblo nations comprise the majority of landowners in this reach.

The following bullet points highlight the promising features and constraints of the Cochiti reach, which provide opportunities and challenges for projects conducted in this area. This list was developed by the Bosque Hydrology Group.
