The collection contains correspondence, documents related to the Ohio State University Natural Resources Institute, copies of bills and resolutions regarding the District, and annotated drafts of The History of the Muskingham Watershed Conservancy District," separated by chapters. The collection also contains interviews Eckelberry had with individuals involved with the District, recorded on phonograph records.
