Question: "Does this stream of water run threw your property,
or is it on the property line."
It's on the property line, so it is the property line infact.
Question: "How far is it from the downstream property line
to the upstream proprety line."
It is about 75m long from one property line to the other (upstream to downstream).
Question: "How much drop in elevation from upstream line
to downstream line.[from pictures in your files
not much]"
I am not sure what pictures you were looking at, but I haven't posted or uploaded any pictures of this site. Is there an easy way to determine the elevation? I am thinking maybe a laser level or something? It would be useless to use the bank, since it is varying degrees of side hill with some flat spots. Sounds like I might have to get wet ;-)
Question: "A few picture's would help,and where are you."
I am in New Brunswick, Canada. I'll have to post a few pictures of the site.
