Skeena River Drainge

This is a map of the Skeena River drainage that has some of the largest undammed river in the northern British Columbia area. It shows most of all the river that connect into the Skeena system as well as how close these are actually in comparison to the ocean. The reason this is significant to me is because it is the most amazing place to fish I've yet to be. These rivers hold one of the largest run of wild steelhead in North America.

This is a Map of the Eagle Cap wilderness area. This is one of the prettiest mountain ranges within a four drive of Spokane in my opinion. The valley floor opens in a large mountain basin the literally look like they are coming out of the ground and hurt your neck to look at because there is so much to see. It also has some amazing hikes, small stream fishing, backcountry hunting opportunities, and also backcountry skiing/snowshoeing in the winter months. It is kept in its pristine state by being a wilderness area and not allowing motor vehicles into access it.

This is a map of the Snake River Drainage. The Snake River is my home river and the river I have spent the most time on. It is a wide river that is the drainage for many other river. It is also one of the small percentage of rivers that flow north, which seems counter intuitive for a river system. The river then drains into the Columbia river that eventually flows into the ocean. The Snake river has 3 types of Pacific salmon and also steelhead. Starts in Wyoming and ends in Washington. It is a highly dammed river that has had its natural flows altered by all the dams. The snake river basin has such a wide variety of types of riparian and flow regimes throughout its length of river.
