Need a little entimology help

#1
I ran into this little guy swimmin along the shore at Omak Lk. I feel I should know what it is. My first guess is hex nymph? If it was in oxygentated water I would have thought some kind of stone-fly or helgramite(maybe). Any help would be appreciated. Almost exactly 1 inch long.

The thought of a young dragon of damslefly nymph also crossed my mind. That lake has huge numbers of both. But it didn't look like any I've ever seen. With the mayfly hatches I see there in warmer monthes I thought hex.

It's all about the sauce.....

My vote goes to an early stage dobson. When in the water did it have little swimmer appendages down the side of the abdomen?

It may be the larva of a predatory diving beetle (family Dytiscidae). The larvae have two tails and may have lateral gill filaments.

That`s what I think it is too .
When they become adults , they can rip your arm clean out of its socket if you`re not careful .:ray1:
