Oasis on the Plains Ranch is exactly what is says, an oasis in the Eastern Plains of Colorado. The Republican River runs through the heart of the property and there are several ponds, water holes and natural springs throughout the property. The ranch is terrific for hunting White Tailed deer, mule deer, pronghorn, turkey, waterfowl and a wide variety of small game. The ponds have bass, bluegill, sunfish, crappie, bullheads and catfish.
