Great Salt Plains Lake, Reservoir in Alfalfa County, Oklahoma, United States
Great Salt Plains Lake is a reservoir in Alfalfa County, Oklahoma, with extensive shorelines and saline water throughout. The body of water features shallow areas and coves that support a range of recreational and wildlife observation opportunities.
The dam was built between 1938 and 1941 by the U.S. Army Corps of Engineers following flood control studies in the region. The project responded to past flooding and reshaped the local landscape.
The lake forms part of the Salt Plains National Wildlife Refuge, where numerous bird species gather at Ralstin Island for nesting and breeding activities.
Visitors can boat, fish, swim, and hike or bike around the lake at designated areas. Campgrounds and parking spots make it easier to enjoy a longer visit.
The western shoreline displays selenite deposits with distinctive hourglass patterns, formed through geological processes over millions of years. These crystal formations draw interest from mineral collectors and geology enthusiasts.
