satellite picture of morganza spillway

the white "dot" in the center is the water rushing through the open gates. Lower left corner you can see Melville inside of its ring levee along the Atchafalaya. Bottom right is False River. At the top you can go to higher resolution.

Interesting effect the drainage into the floodway from the open gate is having on the sediment in the forebay.

ALl the nutrient sediment is going to help the morganza and basins. They should thank us.

Looks like no more than 4 or 5 bays open at the time so I would think you are correct that its Sunday

I'd love to see this same sat image in progression from then until now, and so forth

yea i would like to see the satellite of the whole basin as the water progresses. Going over the basin today, i imagine it has made it down to i10 by now

Sweet picture. I can see my camp, or the roof of it.

the water in the corners of the forebay is probably somewhat stagnant and its flowing directly from the river to the gates in that V shape

I know this is a silly question....but looking at that picture it is hard to tell exactly how the river water gets over to the spillway floodwall....is there something you cannot see from this angle?

All that land between the control structure and the river is flooded. North of the spillway the levee turns away from the river and runs south to the spillway. South of the spillway the same thing happens in the other direction. So when the river floods over its banks, the water can reach all the way to the control structure.

yes, but not exactly
there is also a shorter levee that maintains the river between the forebay (flooded block) and the river
this levee gets overtopped early in flood stages allowing the forebay to fill
the forebay SHOULD remain dry except for a flood event every few years
once the water recedes, this smaller levee is repaired and the area that is the forebay can be farmed

Is that channel that leads directly into the forebay area man made?
Posted on 5/17/11 at 1:10 pm to Shankopotomus
that "channel" is mondeau lake often referred to as monday lake on maps. It is part of old river and always has water in it. If you follow the northern edge of the forebay, there is a levee that seperates the forebay from the crop land and there is a second levee that runs back to the southeast that normally seperates the forebay from old river. The little opening in the trees just west of what you called "the channel" is an area of old river referred to as "the ballpark". Did lots of trotlining in this area growing up and we would camp at the end of the levee at the north of the forebay. As river goes down will be GREAT catfishing in the woods at south end of Old River.

Thanks for asking the questions that I was too afraid too ask
Posted on 5/17/11 at 1:22 pm to Fusaichi Pegasus
Hey man, I never claimed to be a floodway expert so I have no fears
Posted on 5/17/11 at 1:27 pm to Shankopotomus
Is there anywhere to get a frequently updated image of this?

Imagine if we did this all in the time in a controlled way. It would stop Coastal erosion a great deal
