Pond viz: 15
Solution tube: couldn't see it from 10 feet away
90 feet: about 50 feet
Upstream fell to about 30 at the duck under... I turned at the hard right about 400 feet and no better
Downstream fell to about 40 at the entrance and stayed about that to the pit where I turned
Lockwood tunnel was the same
One highlight was 600 - 800 feet in Lockwood tunnel was probably 70 feet. Video proves I'm not crazy. Then it dropped again.
