I've been searching to find out when the weir went in May Creek, but it's buried somewhere. It could have been installed when the hatchery underwent substantial changes in the early '70's. (link below)
I vaguely remember something about lampreys and a weir, but I have no idea as to any details and my memory may be totally mixed up on that.....just thought I'd throw that out there.
