I have never been to the area. Is there any kind of waterway for the water released from Lake Conroe to flow through? On Google maps, it just looks like there is nothing but trees.

Looks like it's a gate controlled spillway but not much of a waterway past that. Guess they don't overflow too often

Man those people along the San Jac river and Lake Houston are in trouble,
Whole lot of water has to come out of Conroe.

There are two concrete spillways; a service spillway and the one under the floodgates.

65000 cfs being let out. That’s a lot.

I saw as high as 71k at some point yesterday.
