The Papers of Roy C. and Ardyce L. Johnson consists of documents dated 1960 to 2015, with the bulk falling from 1974 to 1986. The collection documents the struggles to keep the irrigated farm afloat, including financing with the Federal Land Bank and legal issues related to the use of groundwater wells drawing from the South Platte alluvial aquifer. Additionally, the collection covers irrigation systems, the 1980s Farmers' Crisis, and information on the proposed Narrows Dam, which would have flooded the Johnsons' property. Materials include financial reports, legal documents, letters, maps, grey literature, and clippings.
