The Atrato River in Colombia was considered as a location for a trans-isthmian canal, before the eventual construction of the Panama Canal.
This resolves YES if, at any time between now and the close date, there is a canal from the Pacific to the Atrato river.
A canal is any artificial waterway navigable by a boat of any size. The canal will have to connect the Pacific to any part of the river as highlighted in the image.
i would assume for this to resolve YES the canal would have to be navigable by a proper ship and not just a ditch one can row a canoe through? Also would it have to be a seperate canal directly to the pacific or would a canal from the Rio Atrato to a sufficiently navigable part of the San Juan river be enough to resolve YES?
@sarius I think it's easier to resolve if I consider a canal to be any artificial waterway navigable by a boat of any size. The canal will have to connect the Pacific to any part of the river as highlighted in the image.
