I like this idea. However, I have one small issue: this river appears to go directly through my house…
Assuming the river would be identical in depth and breadth to the Panama canal, if every man, woman, and child in the US picked up a shovel they would need to move 305 cubic feet of dirt each. So if we all just moved 1 cubic foot of dirt per day, we could pull this off in a year.
Hey, you’re a numbers guy right? What’s to say we take all that extra dirt and make an island? Asking for a friend
All you need is time and a LOT of shovels…
