Axlrosen finds this tiem via the blog Fogonazos - no I don't know what it means either, but it has highlighted this, the largest drain hole in the world.

This water passageway is the usual spill method for the Monticello Dam in Northern California.

It blows out its hole with great might.

More pics at the blog entry linked to above. They link to this site which explains it in some detail. Apparently the engineering term for this type of spillway is 'morning glory spillway', and they use the term 'glory hole' for this particular one. I decided not to attract Google links by using the term as the subject for today's item.

I hope they don't allow boating when the water level is high.

sign me up!
 

I guess to some, that would be an appropriate Valentine's Day image.

I'm never dissapointed in IOTDs that use 'big-ass' in their title....

UT said Gl0ry h0le. huh huh huh huh huh

Just what I need, another draining hole.

Someone with mad 'Shop skills needs to insert a crane with a giant rubber sink stopper on a cable hovering over that drain.

Wow. It's like the resting place of the Water Sarlacc!

Man, what a ride. :speechls:

it looks strangely like the portal from Sliders

wonder what parallel world is on the other side ;p

It should be swirling counter-clockwise, this big ass-drain hole.

Man, what a ride.

A dam a few hours away had to put a fence around there "HOLE " because drunk idiots were waiting for the water level to drop ( when there was just a trickle running thru ) and jumping down the "HOLE " on rafts , After 3-4 of them came shooting out a piece at a time , the Gubment put up the fence .

I used to work with a guy. the guy was named Dave. Dave used to manage an adult book store. The book store had those little booths in the back with the coin operated porn movie machines. Shortly after he took the job, he realized that there were glory holes between these booths. Disgusted, he patched them over with plywood discs. After a month, his video sales had dropped in half. So, he removed the patches, and sales went right back up.

here's some scale of the "OUT pipe "

Yeah, 72 ft diameter at the top tapering down to 28 ft dia at the out pipe. 48,400 cubic ft per second max. I wonder how long it would take to make it through the 700 feet? :idea:
