The Pearl River Valley Water Supply District issued the following statement.
Following this morning’s conference call with the National Weather Service, Pearl River Valley Water Supply District increased the discharge from Barnett Reservoir to 45,000 CFS.
The unprecedented amount of rain over the last two days has yielded a predicted inflow to the lake of 56,000 CFS. The lake currently stands at 298.0 feet above mean sea level.
The NWS predicts the 45,000 CFS discharge will result in a river level in Jackson at Highway 80 of 34 feet. Water will be in several streets in Jackson.
It is likely that the discharge will have to be increased again during the next several days, which could result in water entering homes. By Tuesday the river could go to 36 feet.
Residents in low-lying areas should take precautions now. This high water event is predicted to last 7 – 10 days.

36' will be a real problem especially considering the empty suit who is at the helm of Jackson at this time.
Chowke will be able to blame the flooding, pot holes, and low water pressure on these releases, along with white flight, gunshows, open carry, and a vast right wing conspiracy.
No biggey; Chowke can't see the flooding from his gated compound nor from his Atlanta 5* hotel.
Y'all can follow the water levels in Jackson here: https://water.weather.gov/ahps2/hydrograph.php?wfo=jan&gage=jacm6
Water water everywhere, nor any drop to drink.
gonna be literal shit in folks homes in Jackson.
Sounds like the Rez might have learned something from the past. In 1979, there was a 21" rainfall at the headwaters of the Pearl, in Neshoba County on Sunday night through Monday. It hit Jackson on Friday, leading to the Easter flood.
Yesterday, there was 15" of rainfall in Neshoba County and east Mississippi - it will be hitting the Rez soon. The difference this year is that Jackson also got heavy rains (5" yesterday in the city, a record rainfall for Jackson.)
Glad the Rez is dumping some of that 298.0 feet - would hate to see that new parkway on the lower part of the dam be found hung up at the bridge on Lakeland.
Yikes! Remember what 36 Feet was like in 2020?...
One way to rinse the raw sewage and trash out of Jackson and on down stream….
The forecast is for 36' on Monday/Tuesday timeframe. That should douche out the boo boo in Jackson.
Interesting tidbit from the NWS regarding Pearl River flood-stage impacts:
24 (feet) The Jackson waste water treatment plant loses its natural outflow and must initiate pumping.
"Captain! We can't hold the boo-boo any longer! Permission to pump!..."
The all time record Pearl River gauge reading at the Highway 80 gauge in Jackson was 43.28 feet in the 1979 flood. Certain homes had water up to the eaves of the roofs, more or less 8 feet above the floor of the home at that time. If the river gauge at Highway 80 reads 36 feet, how wet will your shit be, right?
Let er rip!
"Captain! We can't hold the boo-boo any longer! Permission to pump!..."
Worse than that.
It means they must pump the treated effluent to maintain treatment operations.
If the pumping doesn't operate properly for some reason (why would it?) then the boo-boo treatment plant doesn't treat the boo-boo.
At that point it probably becomes 'sh*t flows down hill' to a significat degree.
This may get damn ugly.
“We’re seeing right now about 70,000 cubic feet per second coming into the reservoir, which would give us approximately 36 feet on the Pearl River gauge,” he said. “On the gauge at Lakeland, [it is expected to be] 41.5 feet Monday afternoon.”
This is will give the mayor more doom and glood climate change ammunition.
There are some hateful people on JJ page.
Mayor will just claim he solved the water pressure problem!
If that Reservoir levee breaks, shit is gonna get real.

It seems it's always a crisis situation after these big rain events. Why would they not start dumping water at a more manageable rate when they realized the water it was producing was flooding Dallas 4-5 days ago? So what if they miss the mark and the rez is down a little low for a little while, it'll catch back up.
"Give it 10 days and it will be water under the bridge, right?"
You A-holes sitting high and dry need to watch your mouth. This is not anything to joke about. This is about people losing their homes! You are some sick individuals...
@5:59 PM Chill out snowflake. @4:15 PM is making fun of Chowke, and not minimizing the flooding potential.
Probly shouldn't have bought/built in a floodplain.
@2:32 Where can I read more about this? Is there a real engineer in the house that can give a professional assessment of such a situation before, during, and after a levee break?
i'm not an engineer, or an expert at any of this. but, my daughter's girl scout troop toured the spillway one day and they explained, from what i remember, that if the water gets too high in the reservoir, that gravel section close to shaggy's gives way and the reservoir starts to empty out from that location. the houses around the reservoir will not flood.
the water goes across both streets and is supposed to be routed back to the pearl by the geography of the surrounding land.
there are no explosives at all buried in that section. the water just starts washing out that gravel, and then there is nothing you can do to stop it. the reservoir will drain until it stops. it won't empty out, but the flooding downstream caused by that happening is gonna be much worse that the flooding caused by releasing extra water through the gates.
it sucks for anyone affected.
The emergency spillway will not break. The gates at the reservoir can release a maximum of 250,000 cfs. Even in the Easter flood of 1979 the reservoir only released about 125,000 cfs. Without going into a long explanation, the reservoir (since 1964) has been very useful in keeping Jackson and everything South of the dam from flooding a lot worse. FYI: I do not live at the reservoir.
From the NWS (NATIONAL WEATHER SERVICE)
The inflow of water into the Ross Barnett Reservoir reached a peak of 162,000 cfs around midnight on April 16th, 1979, and the Ross Barnett reached its peak discharge of 125,000 cfs around 9:30 am on Easter Sunday on April 15th, 1979. The Pearl rapidly rose and finally reached a record crest of 43.28 feet at 3:00 pm on April 17th, 1979.
It sure would be nice to have some flood control right now a la the one lake project.
I hope the self-involved white Bourgeois environmentalists who have been opposing this are over in East Jackson stacking sandbags for the houses of those who they’ve forced flooding on behalf of some turtle no one has ever heard of. The pearl river keeper crowd are the ones that are directly responsible for all of this mess right now. They should at least have the decency to look the people they’ve screwed in the eye while their homes flood.
@1:29 What a warped boomer viewpoint.
