More Rain! [Sep. 12th, 2009|11:04 am]

[Current Mood |happy]

It started raining about dawn this morning and has been raining steadily since...Richard checked the gauge about half an hour ago and it was 4.3 inches (that's yesterday's 3.8 plus today's 0.5)

Good, good rain.  The creek will undoubtedly rise, though whether the rain will total out as enough, in the long run, to get the springs flowing again, I can't know at this point.

Make that 5+ inches total and it's still raining and expected to keep going for hours.

Sounds just what's needed. :) Do you know if it's also raining over the area needed to get the aquifers restocked, that you mentioned?

Mind you, I should think that the animals that live in burrows aren't too happy.

The prairie crayfish, who live in burrows, are delighted--yesterday afternoon late they were already putting up their chimneys (in a drought they go deep and wait it out...) The cotton rats probably aren't as happy with it, but their burrows are intricate and have sleeping chambers elevated above the runs.

There's at least some rain over the recharge zone, though I can't tell how much...the storm-total display on the weather site reset today and I didn't look at the amounts displayed earlier. But if you take a place like Real County, for instance, and the counties north of it, that's pretty much all rock. Either it's impervious, and even an inch of rainfall will produce runoff, or it's porous and the water will go in and feed springs. Runoffs in that area go into rivers that go across (or stop at) the recharge zone. An inch of water on twelve acres = an acre-foot of water, which is 43,560 cubic feet. If you put it in a cubical box, it's 208.7 feet on a side. There are about 7.5 gallons to a cubic foot, so that's about 326,700 gallons.

Someone at the feed store reported they'd had 9 inches up by Stillhouse Hollow reservoir. That's not Edwards recharge, but it is going to help bring that reservoir up...just the water falling on the reservoir, plus of course the water that runs in.

Prairie crayfish? They sound amazing, we only have stream/river dwelling ones over here. Re burrows, I was thinking of the snakes and perhaps tortoises - I think you may have some of the latter? Do you get the G. Agassizii near you, by any chance?

We were watering here today, having had only a mere smattering of rain in the last month. Not that I'm saying it's anything like your drought, of course!

We have no tortoises. Wrong soil, I suspect. The snakes aren't bothered by rain, as far as I can tell.

Prairie crayfish are adapted to living in alternating wet/dry conditions, though they can die in a prolonged drought. They can burrow quite deep. There are several species, but I'm not sure which one lives in the prairie area (one that I've seen and photographed in the creek is probably _Procambarus simulans_.

And now the total's up to 6.7 inches. The rain's tapered off, though, to a faint sprinkle. Supposedly we're getting more a little later, and more again tomorrow.

Almost seven inches! WOW! And slow enough for a lot of soaking in -- outstanding!

Ahem, I think an acre-foot is 209 feet square by 1 foot high, not a 209-foot cube.

And now we're over 7.5 inches.

This is a Mighty Rain. Pictures on the 80acres blog, though we hadn't gotten to that many inches when they were taken.

I'm sorry. I've been through this, every drought year, so I do feel your pain. Though at the moment, I'm sure you find that hard to believe.
