Could someone tell me what kind of fish this is?

When we fished that lake years ago it was choked with trout.  It was amazing fishing and the the salamanders were everywhere.  It was one of my favorite lakes.  It was also one of the clearest lakes I have ever seen.  You could seet 10-20 feet to the bottom and count literally hundreds of salamanders.  To Bad it now has squafish....especially if they are fish eating machines.  Sounds like the could devistate a lake that size.

There are a ton of them in Lake Washington.  I hate them.  They take my worm when I am fishing for perch!

Isn't there still a bounty on them or did that go away?

The dams around here used to pay people to catch them around the dam fish ladders because they eat so many salmon smolts.  Haven't heard of any "Squawfish Derbys" lately.
