Imperial National Wildlife Refuge

Imperial National Wildlife Refuge Welcome to the official page for Kofa, Cibola and Imperial National Wildlife Refuges! It includes more than 15,000 acres of federally designated wilderness.

The Southwest Arizona National Wildlife Refuge Complex is the administrative office for Imperial, Kofa, and Cibola National Wildlife Refuges. Imperial National Wildlife Refuge was established to protect wetland habitats along the lower Colorado River. Kofa National Wildlife Refuge was established for the protection of desert bighorn sheep and other native wildlife. Cibola National Wildlife Refuge was established to protect and recreate the marshes, backwaters, and meanders that historically provided wintering grounds for migratory waterfowl and other wildlife along the lower Colorado River.

Due to the recent collapse of the bridge on Hart Mine Road upriver at the Cibola National Wildlife Refuge due to suspected fire damage, there may be floating debris in the water. Use caution and stay alert when boating upriver.

This special Memorial Day issue of Conservation History pays tribute to 37 colleagues across 14 National Wildlife Refuges and two National Fish Hatcheries who made the ultimate sacrifice in the line of duty from 1904-2024. Here at Imperial National Wildlife Refuge, we remember with honor Ike Kindler (1924-1948) who was hired by the U.S. Fish and Wildlife Service in 1948 after he served in the U.S. Army during World War II. We invite you to read with us and remember. ​
