Flood protection cost savings

This article needs sources. It makes allegations regarding the cost savings from flood protection but does not provide a source. —Preceding unsigned comment added by 76.200.154.96 (talk) 07:01, 24 August 2008 (UTC)

This is a very nice, well-written article. I've only a few minor comments:

• "it is the tallest dam in the U.S." - I added " as of 2012" - is this correct?
• NealthNewsDigest.com - is this a reliable source for damage prevented?
• "Groundbreaking on the dam site occurred in May 1957 with the relocation of the Western Pacific Railroad tracks that ran through the Feather River canyon." - the relocation of the railroad tracks was the groundbreaking?
• I've made a few edits that you're free to correct.[1]

Damage in February 2017

http://sacramento.cbslocal.com/2017/02/07/damage-reported-at-oroville-dam-spillway-after-officials-increase-water-releases/ — Preceding unsigned comment added by 46.22.104.168 (talk) 12:54, 10 February 2017 (UTC)

Currently there are no photos available with a permit-able license. We will probably see one in a few weeks of the spillway damage. That should be uploaded. Seeing something to scale (people besides or in) will show a lot more than just saying how big it is. Also the damage after use when this is over will greatly increase the size of the hole. It'd probably be good to add the emergency spillway and a photo of the water, and the damage later on. Currently the damage and cost is all just speculation so its good that it isn't put in. Citations will need to be gone through though to be certain that everything is reliable as this is a current event. Rocka1994 (talk) 22:58, 11 February 2017 (UTC)

Semi-protected edit request on 13 February 2017

Update the final paragraph of the "2017 spillway failure" section:

On February 12, 2017, evacuation was ordered for those in low-lying levels of Oroville, due to an anticipated failure of the auxiliary spillway. A failure of the concrete top of the spillway would allow up to 30 vertical feet of Lake Oroville through the gap in an uncontrolled deluge. The flow over the main spillway was increased to 100,000 cubic feet per second (2,800 m³/s) to try to slow the erosion of the emergency spillway.

as follows:

On February 12, 2017, evacuation was ordered for those in low-lying levels of Oroville, due to an anticipated failure of the auxiliary spillway. Specifically, erosion on the hillside was growing uphill toward the concrete lip of the auxilliary spillway, leading to the fear that it would collapse. A failure of the concrete top of the spillway would allow up to 30 vertical feet of Lake Oroville through the gap in an uncontrolled deluge. The flow over the main spillway was increased to 100,000 cubic feet per second (2,800 m³/s) to try to slow the erosion of the emergency spillway.

By the evening of the 12th, the increased flow had successfully lowered the water level to below the emergency spillway, allowing the erosion there to be inspected and hastily stabilized with boulders. The danger is that the damage is transferred to the main spillway. Not only does this make future repair more expensive, but the damage to the main spillway could grow uphill to the point that it endangered the main spillway gates, leaving no safe way to release water. The extent of such damage is currently unknown, hidden by water spray and darkness; it will be assessed on the morning of the 13th.

Thank you! 71.41.210.146 (talk) 06:37, 13 February 2017 (UTC)

Partly done: I have added the requested changes. However, I have changed some of the wording and grammar (to put things in the past tense), and omitted potentially contentious changes not supported by the sources. Please resubmit your request if you would like additional changes. --Vandraedha (talk) 08:55, 13 February 2017 (UTC)

2017 Spillway incident

I've attempted to reorganize the existing text of the incident into a logical progression and coherent narrative. I've added sub-headers in an attempt to clarify the timeline and avoid confusion between the failure of the primary spillway and the use of and failure of the auxiliary (emergency) spillway. These subheadings may not be the best solution long term, and they but I hope that they will help keep things organized temporarily until the incident evolves further.

I have also changed several mentions of emergency spillway to auxiliary spillway. Although most of the locals and many news sources use the term emergency spillway, I believe that using auxiliary spillway is a more clear and accurate description. AFAIK, this is also the term being used by the California DWR. Although it may be more correct, I think that emergency auxiliary spillway is just too long and potentially confusing to type repetitively. I'm not really concerned with the exact term used for the secondary spillway, as much as having a consistent name. --Vandraedha (talk) 10:49, 13 February 2017 (UTC)

• I suggest the spillways incidents could be mentioned in the lede. -DePiep (talk) 12:15, 13 February 2017 (UTC)

• We may want to hold off on adding too much detail about the spillway incident to the lede, lest we run afoul of WP:RECENT. Yes, it probably should be mentioned, but the exact wording for the mention will most likely change repeatedly over the next few days/weeks/months. At this time, nobody knows exactly how big of an event this is going to be and there is a high degree of speculation and uncertainty involved in all aspects of it. --Vandraedha (talk) 12:39, 13 February 2017 (UTC)

• The failure of or substantial damage to of any supporting structure of a dam should be in the lead, particularly if it leads to evacuations.--NortyNort (Holla) 13:58, 13 February 2017 (UTC)

2017 Oroville Dam crisis

The content of the 2017 Oroville Dam crisis article is described in more detail in the Oroville Dam article. I suggest splitting in the future, but right now the 2017 Oroville Dam crisis article doesn't have any content that is not duplicated in the other article. epicgenius (talk) 17:48, 13 February 2017 (UTC) Should it be merged or split? epicgenius (talk) 18:19, 13 February 2017 (UTC)

• Oppose @Epicgenius: In my opinion, that is putting the cart before the horse. I think there is too much content in the dam's article on the current crisis (overall slanting the article towards recent events) and splitting it off is a good thing. We should be trimming what the dam article says, not undoing the split.--Jasper Deng (talk) 18:06, 13 February 2017 (UTC)
  • Well, it could go either way. I am proposing either a split or a merge. I'll amend it. epicgenius (talk) 18:19, 13 February 2017 (UTC)
• Merge Current events articles get too much hype. - Frankie1969 (talk) 18:59, 13 February 2017 (UTC)
  • @Frankie1969: Not in general. Notability is irrevocable - once reliable sources have covered it in great depth, which has happened, notability is not in question. And since this is going to be ongoing for a while ($200 million spillway repair at the very least) rather than just an isolated incident, of course it deserves an article. --Jasper Deng (talk) 19:32, 13 February 2017 (UTC)
• Oppose for the same reason as Frankie1969: current events articles get too much hype, so let the original article, strictly on the dam, stand on its own. The crisis article should bear the brunt of the crisis.— Preceding unsigned comment added by Civil Engineer 3 (talk • contribs)
• Wait If there is NOT a catastrophic failure of either the main or emergency spillways, then this should just be an interesting section merged into the MAIN article. Sure, it's a little bigger than the sections on "2005 dam re-licensing" and "Spillway cracking and inspections", but it is still JUST a part of the evolving history of the dam. Only if the worst should happen (hope not!!), THEN this should stay as a standalone article. Jmg38 (talk) 19:42, 13 February 2017 (UTC)
  • @Jmg38: Uhm no. That's not how notability works, either. We all know now that the spillway is no longer in imminent danger of failing, but this coming week's storms will test that. by the way, please don't use all-caps--Jasper Deng (talk) 19:48, 13 February 2017 (UTC)
• Merge - There's no reason to separate it out from the main body article. Most of this stuff is just a product of recentism; when merged into the main article, we won't need to break down the specific timeline in great detail as is presently the case. Titanium Dragon (talk) 21:12, 13 February 2017 (UTC)
• Wait - The dam might collapse soon. If something doesn't happen, we'll merge and if something does happen, we keep this as a standalone article. UNSC Luke 1021 (talk) 21:31, 13 February 2017 (UTC)'
  • @UNSC Luke 1021: Surely you don't actually mean the dam will collapse. The dam itself is in absolutely no danger of failing. It's all about he spillways.--Jasper Deng (talk) 21:52, 13 February 2017 (UTC)
• Oppose Already, this is a major story. Topic deserves its own article. Issue is not if the dam fails, but that failure was seriously possible. Glacier2009 (talk) 21:38, 13 February 2017 (UTC)
