How to get your rivers in the right place

[Tonnichiwa]

Well, I basically live in wonderland when it comes to this kind of thing as the Skagit River flows down from the Cascade range in Canada to the Cascade Range in Washington State, USA, before finally leaving the mountains and making its way to the Puget Sound. 8 miles before it gets to the Puget Sound it splits into two separate forks and then both of those forks form two different Delta's. The island created by this is called Fir Island and is 15.50 Square Miles (40.14 KM sqared).

But where I live is weird anyway because from the town I live in if you travel 15 minutes west you find yourself at the Puget Sound, an entrance to the Pacific Ocean. If you travel 15 minutes east you find the Cascade Range of Mountains It is great stuff for mapping because you could easily imagine Dwarves and Orcs & Goblins inhabiting the mountains and Elves could easily be living in the forests below the mountain range. Mount Baker, one of the larger mountains, is 10,781 feet (or 3,286 M), couldn't be content with just being a mountain either..oh no...it had to go show off and become an active volcano too! And then it got lonely and brought friends! so there five stratovolcano's in the state where I live.

Here are two pictures, one showing a map of the Skagit River and it's split, and another showing how close the Volcano is.

Also, count how many lakes there are on that drainage basin map. I've counted at least 30. And that's in a relatively small area.

...well, technically the only reason the split exists is because of extensive human intervention by the construction of dykes
(reference http://www.skagitcounty.net/Envision...n_overview.pdf )

and the entire area, including Fir Island, is all a part of the delta (from https://en.wikipedia.org/wiki/Fir_Island_(Washington) )

The Padilla Bay Center provided the attached probable map of the area of 10,000 years ago.

The Skagit River once entered Puget Sound at Padilla Bay, but sometime during the past thousands of years, its mouth shifted southward into Skagit Bay. Bayview Ridge to the southeast of Samish Island, was also once an island, like Samish Island, before delta marshes filled in this region.
