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)[reply]

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)[reply]

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)[reply]

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.[1] 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.[2]

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.[3] 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.[4] 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.[5]

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.[4] 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.[4] The extent of such damage is currently unknown, hidden by water spray and darkness; it will be assessed on the morning of the 13th.[4]

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)[reply]

Fix the dead (possibly malicious) link in the Operations section at the end of the paragraph involving the 1997 flood

Should be this:
