I searched the database and apparently was to narrow in my search. I didn't find it! Burl Ives did indeed sing it but I heard it from an old timer up on the South Fork of the Salmon River in 1974-5. He told a story of one of his ancestors teaching it to him - George Fritzer, the guy I learned it from, was a character and I would guess his family may have been involved in the canal's use. He was in his 80s at the time I knew him. If you look on a topo map of Idaho, find the South Fork of the Salmon River and then between Pidgeoun creek and Bear Creek is Fritzer Creek. He lived there until his death in the early 80s. I lived on Pidgeon Creek for a time. Glad to be able to repay you all for some of the songs I've received here! Steve
