Harper Lake Subregion covers nearly 115,000 acres of mixed public and private lands. Located northwest of Barstow in the Harper Basin, large mountain ranges surround the basin, with protruding hills of basement rocks exposed throughout the region. Its desert marsh and wetlands attract many types of wildlife.
No less amazing are the beautiful views and varied scenery that make Harper Lake a favorite recreation destination.
The modern history of Harper Dry Lake dates back to 1942, when amateur archaeologists discovered what they believed to be primitive stone tools in this area. Fragments were embedded in the sediments of the shoreline of an ancient Pleistocene Era lake, called Lake Manix

Harper Dry Lake Marsh is an oasis for birds, particularly of the waterfowl and wetland variety. Snowy plovers, American Avocets, Least Sandpipers, and Killdeer join Wilson’s Phalaropes on the muddy shores. Virginia rails have been known to breed among wetland vegetation that hides marsh wrens and yellow-headed blackbirds.
Harper Lake also contains over 27,000 acres of designated desert tortoise critical habitat. Visitors may also encounter a variety of insects near water sources, as well as rattlesnakes, such as the Mojave or Sidewinder, throughout Harper Lake.
Flora communities include an extensive saltbush community, creosote scrub, and (at the highest elevations) the Joshua tree woodland. This subregion also includes the occurrence of special status plant species including the Barstow woolly sunflower and desert cymopteru.
