No drains when it rains. For real.

Make sure there's no possibility of storms for the duration you'll be there.
Be wary of snow melt off in the winter.
Smaller diameter/capacity drains are more risky...
a freak water main break could trash you on a bone dry day.
When in doubt, bug the fuck out.

I've heard of underground reservoirs or caverns in larger drains that gradually fill, and serve to slow the flow of water through a drain system by holding large amounts of it. When these spaces reach their capacity, they then vent the water through overflow drains, much like the overflow drain in a bathroom sink when the main drain is plugged.

I've been told that this can happen even on a perfectly dry day, and can result in underground flash floods with no precipitation or water main bursts. Now, I've never seen one of these myself, but they are yet another thing to be concerned about underground.

Be nice to know when they are cycled if present...

Drains that run near water tank farms could also be fed large volumes of water if they needed to purge a tank.

That is my worst nightmare.

Shaddup!

Ok. Maybe you're half right.

Looks like the spot right downhill from the old Pillsbury Best Flour building.

Never underestimate the force that moving water can exert. Keep in mind where you'll end up if you do loose your footing.
This worker didn't do that and paid for it.

I would have said any underground exploring not when it rains. I know a lot of Moles who explore. As Blackhawk said you have to pay attention to snow in certain countries as well as rising water tables during the winter

I think it was on the other side of the river, under the 10th Ave bridge. Big drain next to the bottom of the lock.
