Minidoka National Wildlife Refuge, National Wildlife Refuge in Snake River Plain, Idaho
Minidoka National Wildlife Refuge is a protected area centered on Lake Walcott, offering diverse habitats ranging from wetlands to grasslands. The refuge includes shoreline areas, islands, and upland sections that together support hundreds of bird and wildlife species.
Construction of Minidoka Dam and its power plant on the Snake River began in 1904 under the Bureau of Reclamation, supplying water for agriculture and generating electricity. The reservoir that formed was named Lake Walcott. The lake and its surroundings quickly drew large numbers and a great variety of wildlife, which led to the area being protected early on.
The refuge draws birdwatchers throughout the seasons, especially during migration periods when large flocks of waterfowl gather along the water. The wetlands here support species that have disappeared from many other regions.
Visit early in the morning when wildlife is most active and light is best for viewing and photography. There are multiple viewpoints and walking routes around the lake that offer easy access and varied perspectives.
The Idaho dunes tiger beetle, a species of special concern, lives on the refuge's sand dunes. The reservoir also holds the Utah valvata, an endangered snail. The basalt lava flows support one of Idaho's most diverse reptile faunas.
