The state acquired adjacent to the massacre memorial, including Keeley and Loon Islands in Lake Shetek. A WPA camp was established on Keeley Island in the fall of 1934, housing 200 homeless or transient men. They constructed park amenities like the entrance road, campground, picnic area, beach, and sewage system. Using local wood and stone they built structures including a beachhouse, picnic shelter, and causeways, as well as a camp called the Zuya Group Center. Their own camp on Keeley Island was, unlike most WPA camps, designed to be permanent and function as a second group camp. However, when the WPA was disbanded with the onset of World War II the last causeway, between Keeley and Loon Islands, was incomplete. Inaccessible from the rest of the park, the property on Keeley Island was sold. The WPA camp is now used by Shetek Lutheran Ministries.
