Most of the land to the south and east of Hart Lake is privately owned. However, the Bureau of Land Management administers the Warner Wetlands north of the lake. In addition, the land along the east shore is part of the Hart Mountain National Antelope Refuge, which is managed by the United States Fish and Wildlife Service. These public lands offer numerous recreational opportunities such as hunting, fishing, bird watching, boating, and camping. However, some of these activities are dependent on the water levels of the Warner Lakes, which can fluctuate dramatically."Warner Wetlands" , Lakeview District, Bureau of Land Management, United States Department of Interior, Portland, Oregon, October 12, 2009.
