That's a 22 inch female brown that was full of eggs!
It took about 30 minutes to revive her! I dunno what happened; from the time I caught her to placing her back in the stream was no more than 3 minutes; I think she was just exhausted from spawning. She floated upside down immediately so I worked with her until she was swimming in the current on her own and she'd pull away from me when I grabbed her.
