You mentioned you found it near a river, and as I recall, it was a 
fairly large size chain.    I have seen really large  roller chain used 
for opening penstock gates on hydro generators.    Seem to recall roller 
chain on the locks in Seattle used to turn sprockets on gates, but my 
memory could be bad in this regard.   It may have not been in the main 
channel, but one of the overflow gates.
