Honey Hollow Watershed was established in 1939 as the first small created watershed in the United States to be brought totally under water, soil, and wildlife conservation practices. Six farmers living on William Penn Grant land invited the newly formed United States Soil Conservation Service to counsel them in controlling erosion, and the conservation practices begun that year continued under the Service's guidance as a demonstration of the latest and best methods of maintaining soil and holding water on the land. On October 12, 1969, a ceremony on the hillside overlooking the valley of the Honey Hollow stream dedicated Honey Hollow Watershed as a National Historic Landmark, the first agricultural landmark of its kind. In 1944, U.S. Department of Agriculture Secretary Henry Wallace met there with P. Alston Waring, Gene Crooks, and Forrest Crooks. Dr. Hugh Bennett, first chief of the Soil Conservation Service, said, "Poor land makes poor farmers; good soils make substantial farmers."
