New Well Drilled to Support Listed Fish Species at San Bernardino National Wildlife Refuge
Southwest Region, January 29, 2012
Print Friendly Version

With funding from Department of Homeland Security as part of a mitigation agreement for Border Tactical Infrastructure, San Bernardino NWR had a deep well drilled to supplement water in House Pond on the neighboring historic Slaughter Ranch. The pond is fed by a spring and also runoff during the monsoon rains in the summer months. The pond is approximately one acre in surface area and at its deepest is about twelve feet. The pond provides habitat for three species of listed native fish; the Yaqui chub, Yaqui topminnow, and Yaqui catfish; which is the only native catfish west of the continental divide. The pond also provides wintering habitat to several species of waterfowl and other wetland birds. Because of an ongoing drought in the southwest and use for irrigation by the ranch, it had become necessary to provide additional water for House Pond. By maintaining stable water levels in the pond, it will improve water quality and maintain necessary habitat to support these protected species.
