What a very cool idea, If it ever gets to this side of the pond. It has an open slot here in Michigan and we can cover Lake Huron,Lake Erie, Detroit river, Lake St Clair, Anchor Bay, Clinton River a couple of branches, And the defunct The Clinton-Kalamazoo Canal. Which started in Mount Clemens and made it 12 miles toward the west side of the state before it was abandoned 150 years later if you know where to look you can see traces of the aqueduct that carried the canal over the Clinton river a number of locations have water in them. And used as storm channels to the river.
