This benchmark doesn't seem to be listed in the NGS database, from what I can tell. It 'should' (I think) be part of one of the 'Great Lakes Low Water Datums' listed here...

 

http://tidesandcurrents.noaa.gov/gldatums.html

 

probably station #9063020, but the data sheets for the Great Lakes stations don't seem to be available online. The homepage for that station is here...

 

http://www.tidesandcurrents.noaa.gov/stationhome.html?id=9063020

 

but again, no benchmark information. I'd suggest contacting them at co-ops.userservices@noaa.gov

 

I should 'disclaim' that this is just what I was able to hunt up and is kinda guesswork, but the peeps at that email address should be able to give a definitive answer.

 

(edit) Just as an additional note, the 7.5x7.5 USGS topo maps for that area haven't been updated since 1965, so that line is a dead end. The 'new' digital US Topo versions don't show benchmarks.
