A3 Over the past several decades 48 water catchments have been improved or established on the Kofa. These include modified natural catchments, so-called “ring tanks, 12 windmill/well tanks, and buried fiberglass/PVC pipe systems, which represent a newer and generally preferred design. While available to all species on the refuge, many of these were built specifically to suit bighorn needs, while others were constructed with mule deer in mind.
