The Washo Reserve

1,040 acres

Charleston County

Owned and Managed By
The Nature Conservancy
Co-managed with SC Department of Natural Resources

The Washo Reserve is a 1,040-acre natural area owned by The Nature Conservancy. The reserve features a 200 year old freshwater cypress lake and cypress-gum swamp, which harbors the oldest wading bird rookery in continuous use in North America.

In the eighteenth century, the Washo area was purchased by Joseph Blake, whose name is often associated with the reserve. It became part of the network of plantations which prospered on cotton, rice and indigo. Being a plantation owner cultivating the marsh rice field, Blake's main interest was to create a freshwater reserve supply for controlled flooding. This was accomplished by damming a small creek running from McClellanville to the Santee River through this portion of the Santee Swamp.

Civil War and a large hurricane in 1898 were fatal to the Blake Plantation. By the 1900's sportsmen had discovered the value of the various diked marshes surrounding the Reserve for hunting. The Santee Gun Club was founded in 1898. Over the years the club expanded its land holdings in Charleston County to several thousand acres, including the Washo Reserve.

During the 1930's, over 500 nesting pairs of Common Egrets were estimated on the Washo Reserve. Wood stork, now an endangered species in South Carolina, were first observed in Washo Reserve in 1994.

In 1974, the Santee Gun Club donated to The Nature Conservancy over 24,000 acres of property now known as the Santee Coastal Reserve. While the Conservancy deeded most of the property to the South Carolina Department of Natural Resources, the Conservancy retained the ecologically sensitive Washo Reserve.

Recently, The Nature Conservancy has been working collaboratively with partners to help maintain Washo Reserve as a viable wading bird rookery, particularly for the endangered American wood stork. Dying cypress trees and increased amounts of aquatic weeds threaten the interior rookery used by more than 150 nesting pairs of wood storks. A new water control structure was installed to help manipulate the water levels to better manage new cypress growth. In January 2013, 275 new cypress trees were planted, many of those within dead cypress stumps in the interior of the 200 acre wetland. In the summer and Fall of 2013, the aquatic weeds will be chemically treated with an aquatic approved herbicide to promote open water around the wood stork nests. You can follow 9 wood storks on Facebook “Washo Wood Storks” which were tagged with satellite transmitters May 2012.



Washo Reserve is jointly managed with the SC Department of Natural Resources who also manage the surrounding property: Santee Coastal Reserve.


From Charleston:

Take Hwy 17 North past McClellanville and just before crossing the Santee River turn right onto SSR 857 (look for brown WMA sign for Santee Coastal Reserve and Hampton Plantation sign going opposite direction).  Drive a few miles and turn left into the entrance of the Santee Coastal Reserve.  You’ll continue driving on a dirt road until you see the information kiosk on the left.   There will be a small parking area in the grass.
