Hey everyone,

I have just noticed that in this map there is another water source other the the small pool!

Here is how to find it:

First navigate to the center mountain,
Then, find the 2 iron mines,
Next, navigate to the iron mine that is more to the north,
Then, take a straight line to the right until you reach a ditch.

If you observe the ditch a small amount of water appears and then disappear. And, remarkably, you can place a pump house!
I like to think of this as ground-water. Hopefully this fix some extra-long aqueduct problems!

Sincerely,

StanleyK
