Interesting...gpapa's links led to similar results....soooo....do we have a wind event here instead? Debris hitting something important? A wind driven seiche? The other watersheds feedig that lake are minimal...but if Lufkin and Nacadoches got hammered, and they are 50 and 75 miles north north east of there....
That's all I can come up with, the flow down the Trinity isn't very impressive.
This MAY be worse then katrina for southern LA outside of NO..Kartrina winds blew the surge out with winds form the north and they didn't have as much rainwater flowing south

I wonder if it isn't just a rain-induced event, maybe rain plus wind. I don't know the entire makeup of the dam, but a large part of it is earthen, with a concrete spillway. I don't picture a sieche in a body that size, waves maybe, but I don't think that's it. The purpose of the release is stated as necessary for damage assessment, not for level control. THey want to drawi it down fast for some reason.
The flow downstream, based on the charts, is mighty impressive and shows the 80,000 cfs planned release rate. Up stream isn't near that great a flow; but the reservoir may be anticipated as filling from runoff other than what comes in via the upstream river.
I'd have to spend some time chacking other rivers to see if more than local flash flooding is expected due to Rita rainfall.
That dope FNC's Hemmer still has, "the Algiers section of New Orleans 12 feet above sea level." That does not appear to be correct.
here is the Maptech chart site.

According to Harris County Judge and Houston Mayor, it was a wind event that created the problem at Lake Livingston.
