There is a limit to how deep you can dig. Any 'very long' path across an island is probably going to go above the water line at some point. Don't want you to waste all your effort.

No its a pretty low level area with a shallow stream going through it already. I want to make it deeper and easily navigable but its going to be a lonnnnng dig

But hey if you just want to make a canal, go for it. Just make sure you have decent stamina food and a nearby fire hut for the rested bonus. Also a hoe just in case you have to raise terrain to get to a spot that you missed.

I know I could, the idea is to avoid spending many hours on this if there is a mod that can do it faster.
