Nomination for Lake Hamilton Dam

The case file that argued this property on to the National Register: 3,418 words across 29 pages, filed in 1984. Read by 4 independent recognisers, of which at least 3 had to agree before a line was published.

Source document Held by the National Archives in Record Group 79 as reference 84003774, where it exists only as a scan with no text layer. The words below were read off that scan by 4 independent recognisers at two resolutions. Only lines that at least 3 of them returned identically appear below; where they disagreed, the line is withheld rather than guessed, so some of the form's furniture is missing. Spelling is never corrected, so a stray character that all the readers agreed on is the recogniser's and the typewriter's.. Nothing is summarised, corrected or written by this site.
