Why are Ward & Dawson still rising when everything else is falling back to pre-rain pace? And I mean RISING DC up 9", WC up almost 1.5 FEET since the rain. Is it still raining there?
We're seeing this because Dawson and Ward are headwater/upstream gauges. They are much more sensitive to the effects of flash flooding. The downstream gauges are many miles away and will not show flash flooding effects because they measure the stage of a much larger body of water.
The effects of the rain tonight will be to prolong the backflow of bayou manchac across I-10 into the Alligator Bayou/Bluff Swamp/Spanish Lake area. That extra water on that side of I-10, will also cause more Bayou Fountain flooding.

Can't wait to see a negative number in those 2nd parentheses.
Taking my sore back and prayers to the bed. Y'all stay dry tonight and keep up the hard work.

But once the Amite drops below the level of Manchac, does it matter what those 3 little shits are doing?

I think Oak Alley Dr. homes are gonna be just fine. Maybe the ones near 74 on Oak Fields could see higher water in yards, but not close to home.

Not instantaneously. As long as there is water in Bayou Manchac that is higher than the swamp/road, water will still flow that way too, but when the Amite is sucking water at the same time, it won't take long for the overflow to cease.

Well A) they are usually an hour behind with the gages and realtime, and B) water continues to flow into them from drains and what not well after the rain stops. It is the same reason the crest of the Amite River takes 3 days to get from Denham Springs and French Settlement.

The reason I asked is cause the Amite is dropping pretty fast. Bout 1.5"/hr

You ready for this? i'm predicting that the Amite drops below Alligator Bayou somewhere between 7-8p tomorrow night
Posted on 8/17/16 at 11:45 pm to Schmelly
That rain hurt back of Ridge. I've had a 4" rise since 6pm today.

Because tonight's rain will push more water down Ward Creek, that new water will reinforce pressure toward Spanish Lake. If Spanish Lake continues to fill for hours longer than it would have because of the extra pressure from Ward Creek, water will get into more houses in Ascension. If water from Bayou Fountain is prevented from crossing I-10 for another day because of that Bayou Manchac backflow, and we have another storm like tonight, then more upstream areas around Bayou Fountain will be affected.
Most of the water will exit through the Amite eventually, but the time it takes and the rain events that can happen during that time are important to the people who haven't been hit yet. For example, the upper Bayou Fountain area has dodged a bullet so far. If Spanish Lake is full and Ward Creek keeps getting replenished by daily rains, Bayou Fountain is going to go higher than it is now.

frick man. That's puts ya at what? 4" of wiggle?
Posted on 8/18/16 at 12:00 am to p15r
Makes sense. I did the math...with no external factors that my ignorant arse isn't accounting for & maintaining their current paces, the Amite & bayou Manchac will be equal by about 7-8p. Did I waste my time? Lol

Regarding school....
When salmen high got destroyed in Katrina, they made an arrangement with northshore high, since northshore high did not have any damage. Northshore high students went from like 6am to noon and salmen high students went from like 1pm to 7pm. Since some teachers were not able to come back right away, some NHS teachers ended up teaching SHS students and vice versa.
I wonder if the same type of arrangement will be made in Ascension.
