June 4th^...most recent legible pic.

Looks like the Pearl is currently having more influence on the western sound than the BCS, which is doesn't even appear to be discoloring the lake much. Maybe it's just a misleading image though? I dont live near Lake P to have first hand knowledge.

Image is misleading. Water looks like chocolate milk as far east as Petite Bois Island and fish and turtles are in every tide line you come across. The BC spill way is in a bad location. Once the water reaches the mouth of the MS it has a large and deep area to disperse. The MS keeps it bottled up. I went 10 miles south of Petite Bois last weekend and the water still wasn't even trout green.

1927 Flood

So the Bonnet Carre Spillway was built in the 1930's as a result of the historic 1927 flood. By looking at this map it appears that Lake Pontchartrain and thus the Mississippi Sound were not impacted near to the extent as they are now.

So to nerd out on the history: before 1814 or so Bayou Machac drained into the Amite River and then into Lake Maurepas, to the Ponch and down to the Mississippi Sound. Bayou Machac is the route that D'Iberville or Bienville went in 1699 (can't remember which brother went which way) while the other brother went to the mouth from Biloxi to "discover" the gulf entrance of the Mississippi. The shortest route by 15 minutes to the Mississippi was through the lakes up the Amite river and in through Bayou Machac. That route was preferred at the time - which lead to the development of Ship Island, Miss., as the "port of entrance". Andrew Jackson clogged up the Bayou Machac to prevent the British from flanking him and having to fight a two front battle during the Battle of NOLA against superior numbers of forces. The Bayou was not reopened for many years and as time passed while Machac remained unusable the route traveled became known as going through the mouth of the Mississippi at Venice and not up/down the "Rigolets." Bayou Mancha was further damned up/levee about 10 years after the battle - sealing off the southern most spillway on the east side of the river. Prior to the Bonne Carre spillway the river naturally dumped into the Ponch which technically the river still does - if not it would not function much as a spillway. You are correct that since 1927 the COE's mission was first to levee the entire river to "speed it up to scour" which eliminates all manner of other natural spillways from Cairo, Illinois to the Gulf. And since about 1950 the COE has also aimed to prevent the Mississippi from turning west into the Achafalya as the main exit to the Gulf - which is the Morganza spillway. So left all on its own, with no levees anywhere ever, the Mississippi would probably go mainly through the Achafalya basin and the water would be clearer at Horn Island - but I suspect at a certain flood level it would still head down the current path and spill into the Amite first and Lake Ponch second.

I drove over the lake last weekend. I swear the water look much prettier than what's off the beach here in Goula.

the water at Chandeleur has been mixed over the last couple of weeks. one day it will look like chocolate milk, then the next it will be someone clear.

inside the island hasn't produced nothing even close to what it has in the past, I am seeing a lot of debri in the water, and also freshwater matter (grass etc). If you can get out there on a calm day, the outside of the island is were it has been happening. The barrier islands have done a decent job of holding everything inside.

Thanks for the history lesson… if anyone wants to read a great book, "The Gulf: The Making of An American Sea" by Jack Davis is an awesome read.

I've been reading a lot of idiotic comments about this lately on social media and it almost makes me feel ashamed to be from Mississippi. It seems that a large portion of people from the MS coast don't realize that spillway or not all of this water is going into the Gulf of Mexico just a few miles further south and years ago before the levees it was probably spilling into the MS sound much worse than now.

The lack of understanding of the economic importance of the ports of New Orleans and Baton Rouge along with the refineries and everything in between boggles my mind and reminds me how pervasive ignorance is in the world yet today.

The river has been at or near flood stage for almost 6 months now which is unprecedented and that's beyond anyone but God's control....

Ladies and gentlemen... the thread closer and man of reason has weighed in. Y’all spurred his wrath but he speaks the truth.

I'm sure there are some iditoc comments but we can all agree this is an environmental disaster. What other short term options are there except opening up the Morganza Spillway and diverting through the Atchafalaya Basin down the natural flood plain, but no, too much impact there.
Also flood water to the South and being diluted in the Gulf is not the same as the freshwater intrusion into Lake Pontchartrain channeled through the Bonnet Carre.

Id there a website where you can see satellite images of the dirty water flowing into the gulf mixing with blue water?

Went passed Horn last weekend and it looked like chocolate milk. Passed by yesterday and it was back to green, not pretty/clear green, but definitely an improvement.

Still looked like (and tasted according to the kids) river water inside the west end of Petite Bois yesterday. It's going to be a while getting back to normal.

Ehhh, Dont be embarrassed about yer so called brethren from the GREAT state of MS, you wouldn’t be the dude you think you are...., or a few think you are....

Too much fresh water coming down the pike for too long down MS is the prob with not strong enough SE winds. Nothing New, will be “nasty” as long as the current weather prevails...same as forever ago...

It's not the best quality, but it's current.

Updated water report... pretty much back to 'normal' on Petite Bois this past weekend although not sure it will stay that way with the spillway currently open.

There was more rain yesterday so that'll wash down but as long as we keep getting an East wind it should be OK. How's the bayou in Pascagoula did you check to see if any salt had pushed back into bayou?
