The map's name change is reflected at the top of the page. The second dam is symbolized as having a fishway. The area that would be made accessible by a fishway is in the southern extent of the watershed, where the two watershed layers do not overlap. Dams located closer to the outlet of the watercourse have a greater impact on stream connectivity than those located farther upstream. Both dams are on the same river, so they will have similar upstream drainage areas. To determine how much salmon spawning habitat would be made available, you will isolate this region using the Overlay Layers tool. The most prominent location is Tsútswecw Provincial Park, formerly Roderick Haig-Brown Provincial Park. The Salmon SEEson program helps people witness this amazing migration at locations around King County.
