Anyone know what Madison Blue looks like? I'm headed there Saturday.
We were there last week, and there's been no reason for conditions to change.
Basin and front of cave a little milky but fine - vis 50-75 feet out to Martz Sink jump, then crystal clear past there. Flow down - even lower than in October when we though it was really low!

We've been getting some rainfall out here today, scheduled for tomorrow and Sat as well. Also had some rain earlier this week, it could have an adverse affect on Madison which has a tendancy to blow before everything else(specially with a shoddy uncharged aquiffer).
I am due to be down there the following weekend. What will all this rain do to Little River, Peacock, Cow and all the other "usual" hot spots?Quote:

Thats not even funny...I need a break!!!!!!!Quote:

Isn't that the truth. Our clear water is clear AND warm....Quote:

Well, after diving real cold water for years, I will say I' ve never seen anything even close in FL. I will say the water can be as dark here as anywhere I've ever been though

Cold isn't all bad. The sink at Jailhouse in MX feels like warm pee and has the color of baby $hit on top of zero viz if you aren't the first one in. I'll take cold and clear (>/= 1 ft viz) anytime.
They started using deep well injection in MX, several years ago now. Carwash was closed for a period of time because of the bacteria levels so it just might very well be baby $hit.Quote:

On the way out, when you cross the jump to martz it turns cloudy, probably 30' vis all the way to the exit. That was on Saturday.
but warm?Quote:

Here is Forrest with a friend just yesterday. Guess you found it in great conditions on Saturday?

Nice helmets...
That's my wife Tracy with Forrest - they had just finished a dive to the Dropoff. (I was doing a day of "surface support" with a back injury flare-up - back in the water today, though. Great dive at Jug!)
TJ came by with his camera and took the picture - then Tracy pulled out her slate and wrote: "Congrats! You've just had your picture taken with Miss Rodeo Vermont 1981!" They got laughing, and from the surface it looked like somebody was having a free flow. :)

Yea, I think I blew off at least a 100 psi laughing :-DQuote:

The crossunder tunnel is tannic. Martz is fine, but the water is below the last step.
Since when?
Saturday(2/18) the Crossunder Tunnel wasn't bad at all, and crystal clear past the first little drop to 80'ish.
Forrest, Mr. Bug Guy -
Thanks a lot for replying. I'm hoping to persuade my wife to do the Crossunder if we make it to Florida over spring break and the system is still in good condition. This is encouraging.
Like Mr. Bug Guy (Mat) said, the Crossunder isn't too bad, just not clear like the back of the cave, or the Aquaduct tunnel. It will get very silty, after two divers go through it.Quote:

My report was from the 19th, things can change.Quote:

Jim Wayat posted something about madison being all stirred up on Facebook.
Call him ...
"First to go, last to blow..."
So does this mean that the rains up north are recharging the aquifer via rising river levels or simple some river water is siphoning into the aquifer in isolated spots? What does history tell us about past situations like this?
"First to go, last to blow" refers to how Madison Blue has such a short spring run that when the river rises, the spring pool's hydrostatic pressure increases, turning the flow into a siphon. It's usually the first NFl spring to lose its vis, and the last one to clear.Quote:

Based on the size of the waterfall the spring run had become, it would be hard to believe Madison is a siphon ATM. More likely because of the rise in the river, and the low hydro-static pressure of the system at this time, there is probably a ton of tannic seepage (which happens at Madison anyways).
There are certain placed that need to get rainfall for certain spring to get fed. Someone mentioned the Okefenokee swamp for the Luraville/Mayo/Branford area. They were not real sure about the location though.
Rain in the Okefenokee swamp makes tannic water in the river, and causes the river to rise. Good for the water supply, but not for visibility in the springs :(Quote:
