This old brush dam was located about one mile north of Greenwood, on the Black River, near the present Greenwood Park.  A dam, at that site, was difficult to keep in place.  The brush dam was built shortly after 1900 and went out in 1914 with the same flood that wiped out Hemlock Dam, two or three miles upstream.  O’Neill Creek had a similar brush dam under the Hewett Street Bridge in 1900-1910.
