Hydrologic Monitoring for Canon Sapato in the Quarai Unit of Salinas Pueblo Missions National Monument. 2010-2011 Summary Report.

摘要

This report focuses on SCPN hydrologic monitoring activities in Canon Sapato at SAPUs Quarai Unit. The Water Resources Management Plan: Salinas Pueblo Missions National Monument (National Park Service 1997) describes an arroyo extending for a distance of about 150 m through Canon Sapato. The report suggests extensive arroyo incision took place during the past several hundred years as the result of changing land use in the watershed. Outcrops of the Permian Abo Formation occur in the arroyo bottom just downstream from a pedestrian bridge across the arroyo. Presence of this red sandstone probably limits further downcutting while bringing groundwater to the surface, resulting in perennial spring flow in Canon Sapato within the Quarai Unit. A spring-fed pool exists approximately 10 meters upstream from the pedestrian bridge. This pool is the furthest upstream extent of surface water in Canon Sapato. Spring flow supports continuous dense wetland and riparian vegetation extending from the spring pool downstream to the monument boundary.
