re: Major Louisiana Flood Event

Yesterday someone was saying the Toledo Bend dam was vibrating. SRA update shows there is no damage to the dam and everything is operating fine.

My fiancees dad lives along the Sabine south of Toledo Bend.

Thanks for making me type all that out for nothing!

Are you having relationship problems, Farva?

It didn't start raining at airport road until late afternoon. Any totals were from about 5PM until now. According to the radar, more rain is on the way.

Yeah I've been watching that area quite a bit. The vibration apparently is to be expected when you've got all 9 gates opened at 22 ft, the highest they've ever been lifted (26 ft is maximum height). The press release from SRA is pretty ominous, especially the part about it not being a flood control reservoir. The record flooding that will happen downstream is sad, but if they don't release water from Toledo Bend and the dam fails, it would obviously be apocalyptic.

PRESS RELEASE March 10, 2016
Major Rains Cause Lower Sabine River Basin Flooding Event

(Orange, TX) According to the National Weather Service (NWS) more than 16 to 18 inches of rainfall has fallen over Toledo Bend Reservoir within the last three days with more rain expected. Toledo Bend Reservoir, operated by the Sabine River Authority of Texas and the Sabine River Authority, State of Louisiana reached a record level high of 174.36 feet mean sea level (msl) at 6:00 a.m. this morning due to the rainfall event. The current gauge reading is 174.20 feet msl at 3:00 p.m. today. Toledo Bend Reservoir is not a flood control reservoir and reaches full pool at 172.0 feet msl. Spillway gate releases, which protect the integrity of the dam, have reached a record of 207,644 cubic feet per second (cfs) which is 90,000 cfs over the previous record set in 1989. Currently 9 gates are open 22 feet and 1 generator is running 24 hours/day. There is no truth to the rumors that the Toledo Bend dam could break due to the record releases. The integrity of the dam is intact and is operating as designed.
