Madison CLOSED

[JCDdiver]

I dove Madison either last year or the year before when the river was up. The basin was tannic with reduced visibility (~5-10' of vis) all the way to Martz. It seemed as though there was a significant amount of tannic water coming from the Cross-under tunnel.

I think there is a new river intrusion, somewhere near the front of the cave. I have never seen the front all tannic like it was t weeks ago

Changing hydrodynamics with the drought

[OH]

Yep it was pretty dark
I'm glad I got to do few dives there before they closed it
