Talk:Morganza Spillway

message: What's it actually say?   Who gets it?  Just the people in the Morganza floodway alone?   Technically speaking, from the point the Morganza floodway  and Atchafalaya Floodway join, what do you call the combined downstream area?  And from that same spot, if you go UPSTREAM in the Atchafalaya Floodway, do those folks get the letter?  After all they could get worse flooding if water from from the spillway backs up the Atchafalaya Floodway from the junction.NewsAndEventsGuy (talk) 00:49, 15 May 2011 (UTC)
replies: text: I'll see if I can find a source for the article as to what do you call the combined downstream area. The other points you raise might be good for this or one of the related articles. -- Uzma Gamal (talk) 00:29, 16 May 2011 (UTC)
thread_title:  Letter the USACE sends to people below the spillway 

message: Media reports are rife with how much flooding will happen in the Atchafalaya Basin due to the opening but hardly anyone is daring to ask how much would be happening regardless?  Let's think about two things:  (1) geographic extent and (2) depth.   The innundation maps seem to show almost identical extent.  I confess I haven't looked at them really carefully.  But it looks like there will be SOME flooding all over the place.  So just thinking about geographic extent I fear the outcry against the corps for flooding "me" to save "them".  On the other hand, there's depth.  entering speculation here....  with the spillway opened, maybe what would have been "some" flooding becomes really really deep flooding.  So buildings on piers that would have been above the water without the spillway open might now be done for.   Crop lands that might have retained soil might suffer extreme erosion (or maybe more rich sedimentation?)  Anyway, I hope someone finds some good analysis to share.   If the governor of LA was saying a heap of acres downstream of the floodway were going to flood regardless, we need some perspective on just how much "worse" the situation is because the gates were opened.  The corps will be on the short end of the stick for complaints.... but how much will the corps actions be responsible for the damage?NewsAndEventsGuy (talk) 01:11, 15 May 2011 (UTC)
replies: text: The whole lesser of two evils issue and liability issues might be better covered in 2011 Mississippi River floods. I doubt anyone ever produced a good analysis on the what if the gates were not opened in 1973. They blew up homes to set a fire break during the 1906 San Francisco earthquake and the main issue ended up being who was going to pay who. Jinda probably was presented with analysis on the options of opening or keeping the gates closes and those options would be part of the state governments papers. Perhaps someone can locate them for the article. -- Uzma Gamal (talk) 00:37, 16 May 2011 (UTC)
replies: text: Those are important angles (less of two evils and liability) but that's not what I'm getting at.  Instead, I'm asking about intellectual integrity.... let's pretend the flood was smaller in equal proportion to what comes down Morganza Spillway.  A heap of the Atchafalaya basin is still going to flood even at that reduced volume.   So.... when we say "The corps will deliberately flood the "Atchfalaya basin to save New Orleans" that's not 100% accurate and precise, because so much extra water is ALREADY coming down from Old River Control that the Atchfalaya basin is ALREADY flooding (or will).   Its more accurate to say the corps will deliberately exacerbate that flooding by diverting from  Morganza.   But this nuance is lost in the media, so hotheads get to scream at the corps for every single solitary drop above flood stage in Atchfalaya basin.  That's wrong, intellectually speaking, but is this an important distinction?  Maybe, maybe not.  What I would like to know is how much will it be exacerbated, vs the higher-than-normal flow from ORCS.Italic text    NewsAndEventsGuy (talk) 15:44, 17 May 2011 (UTC)
replies: text: There in lies the essence of Wikipedia. I agree it may make more sense to focus on how the corps will deliberately exacerbate that flooding by diverting from  Morganza (and, of course, how it was the failure of the Government's dam, and not Hurricane Katrina, that resulted in the damage). However, Wikipedia's policies result in Wikipedia merely reflecting the media - "a representative survey of the relevant literature" such that "the threshold for inclusion in Wikipedia is verifiability, not truth." What other organization do you know works so hard to produce information but informs everyone that "Wikipedia articles are not reliable sources for any purpose"? It is a hard thing for new editors to let the media tell the story within Wikipedia. However, that is what distinguishes Wikipedia from the rest of the Internet. As you note regarding alternate vs. exacerbate issue, "this nuance is lost in the media." That means it has no place in this Wikipedia article (unless you find a reliable source that discusses it). Once you embrace the concept of letting the relevant literature tell the story within Wikipedia even if you do not believe it to be true, you will begin to understand what makes Wikipedia Wikipedia. -- Uzma Gamal (talk) 10:40, 19 May 2011 (UTC)
replies: text:  Kindly look again.  Please not that in the ARTICLE I had added a reference for the fact that the waters mingle. Fact-citation-article.    Then, when I unsuccessfully sought references for the degree-of-exacerbation issue, I did _not_ post it in the article.  Why not?  Because as I said in this TALK thread, the nuance is (so far) lost in the media!  Hopefully some reporters reading these pages for story ideas will run with this one.NewsAndEventsGuy (talk) 23:56, 19 May 2011 (UTC)
thread_title:  Did the Corps flood '''''___MY___''''' farm?? 

message: This topic is deserving of a stand alone article or at least be part of a broader topic article such as 1973 Mississippi River floods. You might find some information here. For the broader article, I did find :File:Morgan City Louisiana Aerial 1973 Flood.gif and :File:Pierre Part Flood Mailbox 1973.gif. -- Uzma Gamal (talk) 13:22, 16 May 2011 (UTC)
replies: text: Those and more than a dozen other images are in :Commons:Category:1973 Louisiana flood. I agree we could use an article on the subject. Infrogmation (talk) 16:11, 16 May 2011 (UTC)
replies: text: Two articles created 1973 Mississippi River floods and Mississippi Flood of 1973 need to be merged. From what I can tell, year last and "Flood" singular and capitalized seems to be the standard, so I suggest that the latter be the destination page. --Kkmurray (talk) 01:11, 21 May 2011 (UTC)
thread_title: First opening of gates (1973)

message: I noticed in this edit, User:Ebnpebnp says, "The floodway is the path the water takes, the spillway is the control structure". That sounds reasonable, but the Army Corps of Engineers doesn't seem to be stickin by that terminology, specifically referring to the control structure as the "Floodway" in the captions of their public photos, eg :File:Forebay side of the Morganza Floodway.jpg, :File:Gate of Morganza Floodway.jpg. Some of the South Louisiana media seems to be using the terms interchangeably as well. Any clarification? Wondering, Infrogmation (talk) 16:19, 16 May 2011 (UTC)
replies: text: *Ebnpebnp is absolutely right. Maybe the Corps may be referring to the entire project or complex as floodway. "Morganza Spillway" is most common in searches as well.--NortyNort  (Holla) 21:45, 16 May 2011 (UTC)

text: *The Army Corps of Engineers isn't the arbitrator of the floodway/spillway terminology issue.  They may be intentionally misusing the terms in an effort to try to limit their legal liability down the road (like they did by blaming the damage on Hurricane Katrina (act of God) rather than their failed dam (human design/construction defect). Who knows. A representative survey of the relevant literature can resolve the floodway/spillway terminology issue. However, given the volume of info on this topic, it will take a while before such an issue is resolved. Until then, I think we should continue to distinguish the two via the idea that "The floodway is the path the water takes, the spillway is the control structure" since it seems to make sense. Otherwise, the article will end up confusing everyone. -- Uzma Gamal (talk) 10:53, 19 May 2011 (UTC)

thread_title: Spillway/Floodway

message: TeamNOLAcoe, your edits are not appropriate and I will revert the bulk of them. The structure is a spillway, and the recent change to the article's title, without discussion, is wrong. See the above comments by Kkmurray, and especially the sign adjacent to the road over which many people travel. 4. It is incontrovertible that the Corps calls it differently at times, but they often have internal reasons to use a particular nomenclature. So if the US Navy insists on calling their ship a boat, might we consider using their naming convention? Sure, but if the official name of something is a "United States Ship" and others call it a ship, we might as well use the names that consensus deems appropriate.
I propose that the consensus name for the structure is Morganza Spillway. This is the odd fact: all of the newspaper articles used a sources for this article use that name, and you have changed all mentions of this official name in the article except where the title of a Source uses this name. 
Furthermore, TeamNOLAcoe, you are seemingly identifying yourself as some misguided member of the New Orleans Corps of Engineers. Shame on you for doing a disservice to this website by obfuscating the proper name.
And as icing on the cake, I had personally added a sourced piece of information regarding an embarrassing mistake made by the Corps. During the spillway opening, the estimated flow rate had been grossly underestimated by the Corps. I noticed that you, TeamNOLAcoe, removed any mention of the findings by U.S. Geologic Survey and replaced this with a figure not found in media reports of the day... . While I believe that this is likely to be a good figure, I will be that this number is from lengthy post-analysis by the Corps, and that you are privy to this data as a member of the Corps. Why no mention that the Corps originally estimated ? Why no analysis of the -37.4% error in your estimate? Why did you leave my source and change the article?
Here is the source for the Corps' error: http://www.mvn.usace.army.mil/news/view.asp?ID=482 and a quote:
Beginning on May 18th, discharge measurements were taken onsite by our federal partners at United States Geological Survey (USGS) to validate the computed measurements.  A significant difference in the computed and measured discharge rates was discovered.  After a review of this difference, it was determined that the computed flow understated the discharge from the Morganza Floodway. “Thanks to our strong partnership with the USGS, we have better tools to make decisions based on the best science and modeling efforts available,” says Ken Holder, Chief, Public Affairs Office. [...] Working closely with our partners at USGS, we have determined the Morganza Floodway was discharging at a rate of 172,000 CFS with 17 bays open, well below our initial estimates of 300,000 CFS, instead of the reported 114,000 CFS.  This discharge of 172,000 CFS is well within the water control plan for the structure, which is designed for a 600,000 CFS capacity.  The discharge measurement has no effect on gate operations at the Morganza Floodway.
I hope you are not an engineer or an official at NOLA COE. I hope you are the janitor or something. I like to saw logs! (talk) 05:00, 13 November 2011 (UTC)
