You can relocate otter and beaver, you don't have to kill them. I do it all the time. When I took the class waaaaaaaaay back in 1985 we could relocate everything except raccoons, possum, nutria and eastern gray squirrels. Than around 1998-99 I took the class again and not mushed changed. So until I and "all" 265 WCO's get a order from WDFW that says kill everything and when they say to do that I will question why. So I will tell you relocate otter and beaver, there is no reason not to. Until I see "Law RCW's"

As for relocating animals like Otter and Beaver across the mountain, that they will not allow. There was a congressmen that wanted beaver relocated over to eastern Washington years back and once he found out they they wouldn't even survive the ride than his eyes opened up. What do you think you could charge to relocate a pair of beavers over to say Okanogan County where he wanted them? And to top that off, do you think they could survive a 5-6 hour drive and could you guarantee they would ?

WDFW does not want them moved from one side to the other just because of the possible diseases.
So I wouldn't even consider driving them to far. If you catch them go throw them out on one of the big rivers. From Seattle, try the Snoquamie river.
Contact me sometime and we'll get together and I'll tell you a lot of stuff that WCO's need to know.
