Beale Street flooding does not mean track underwater. The railroad passes over Beale and there is a sag point in Beale under the RR. This location floods at a much lower river stage than the current one. The point of concern are further north along Riverside Drive, although I think this area remains above water, and at the Wolf River crossing.I travel the CONO both to NO and to Chicago via origination station in Memphis. There is a portion of the track in Memphis near the Pyramid that is very close to the low lying area of the Mississippi and that portion of the city has "a lot of flooding issues". There are posted pictures on Facebook of the area around the pyramid that shows the water steadily rising with evacuation orders orgoing. Portions of Beale Street are under water.
Dumping water through the Bonne Carre will have no affect on the CofNO route. Effect on the Crescent route is also unlikely. Remember, the NS bridge over the east end of Laake Ponchatrain is six miles long. It takes A LOT of water to get the level high enough to get to that bridge. In fact, the only thing that has, so far as I know, has been when a hurricane has driven Gulf of Mexico water into the lake.The spillway is in fact diverting Mississippi river flood waters into lake Ponchartrain. This has the potential to affect the Crescent.The SL might be effected if they open the Morganza Spillway NW of Baton Rouge. The water will flow down the Atchafalya flowage and impact Morgan City in a few days. Besides water, Morgan City has flood gates on it's levies which, if closed, would block rail traffic.
They've already opened the Bonne Carre spillway which the CONO crosses right along Lake Ponchetrain. But that's probably of no concern as the CONO isn't running now.
Likewise, the Morganza spillway will not affect the CofNO route. it opens flow to the west and the CofNO is on the east side of the river. It could possibly affect the Sunset Limited route.
