How much rain would it take to really make a noticeable difference?

It would be sad because the water level would be so low that we would all have to dry cave to the water, which would now be a sump? I think . . .

I "dry" cave to get to water all the time. Is isn't at all "sad". Look at the link in my signature line :-)

Unfortunately most of our caves likely rely on the hydrostatic pressure to keep the roof up...

I think you took that the wrong way. Nothing is sad about being a sump diver, heck I want to learn more about it, what will be sad is when we are sump divers because places like peacock have become dry caves and sumps. That is what I was getting at.

Most of the water we pump out of the ground ends up in rivers that flow to the ocean, Even Agricultural irrigation has to have run off, without it salts build up in the soil from evaporation and that isn't good of course. It's a double whammy, we are polluting the soil and therefore ground water, and the flow through the aquifers is less which has the result in concentrating the pollution. How many think that the increase in nitrates and possibly phosphates is why the Mill Pond is overgrown with weed? I had never seen th eMill Pond more than a year or so ago, but some of the videos from a few years ago are astonishing at how weed free at least the swimming area was.

I know, didn't you see the :roll: :-D

FWIW: This has been happening in Australia for decades. The water level is down 30-40 feet in the last 30 years. It is even worse in the Nullarbor desert. You have to go 1000' back into a "dry" cave, and 300' down, to get to the water.

Gee, I thought that meant that you were repairing the pumps in peoples basements.

Have the increase in sinkhole formations over the last decade not been connected to a depleting aquiffer?

If we had a good week of rain storms in the north Florida area, would that be enough to raise the water level at a place like Cow or Peacock Springs by a couple of inches? Or does it take more than that?

If I lived in cave country, I'd probably slip up to a place like peacock springs for a couple of days after a good long rain to see what effect it was having on the spring itself. But maybe some folks with better knowledge of the effect of rain on the aquifer can help me out by volunteering some information on this topic?

It's my understanding Florida has been in a drought conditions for many years. This maybe heresay or act.
