January 17, 2011: Hello, Got your contact info on bytown.net. I am looking for an early map that would show the ottawa river as it was before the dams. In particular, I'm interested in the section from Castleford to Chenaux (Portage du Fort). I'd like to estimate the original water levels at my property, near Steamboat Channel, by comparing the shoreline and islands visible then and now. This could help me to look for logging artifacts on the shore, if I can determine where the original shoreline was. Any leads to historic maps in museums etc., would be appreciated. ... Mike
