Nina, sorry I can't be of much help. It certainly hasn't been reissued on CD and I'm fairly sure it wasn't reissued on LP either. The details of the recording are: 'Back Water Blues' Uncle Dave Macon (vcl, bj) and Sam McGee (gtr), recorded 11 May 1927 in New York City [Vocalion 5164].

The Meade, Spottswood, Meade biblio-discography listing of the Macon recording gives a reference to Bessie Smith's 'Back Water Blues' recorded on 17 February 1927 in New York City. You can find a reissue of this on vol 3 of Sony's complete recordings of Bessie Smith in the Columbia Legacy series. Although about losing a home in a flood, the Smith recording predates the April-May 1927 Mississippi River valley flood that covered an area of 9000 miles.
