Oroville Dam's Recently Reconstructed Main Spillway Fundamentally Flawed No dumb questions. A "SPILLWAY" is the channel that they use for flowing water out of a lake once it is near full (how near to full depends upon the lake and it's purpose). Water goes out the spillway, which is located at a level near the top of the dam, but often NOT on the dam structure itself, by gravity and then flows downhill, eventually reaching the old river channel below the dam. On major dams for the spillway (or sometimes spillwayS) there are GATES that are lifted to allow MORE water to flow out of the lake, and lowered to permit LESS water to flow out of the lake, depending upon how high they want the lake water level to be. In the case of the Oroville Dam if you go look at it via Google Earth or Bing Maps (click on the satellite option - Bing is better in this case than Google) you can see that the spillway is off to the side and away from the main dam structure. You can also see the control gates that are raised or lowered to control the outflow of the water into the SPILLWAY CHANNEL. It is the Spillway Channel that has suffered serious damage (if you look at the pictures) AND the damage is severe and undermining the entire spillway itself. If the undermining would continue, depending upon how they built the control gate structures at the top of the dam, it could undermine the entire channel such that the control gates structures would FAIL ... and then the lake would start to release uncontrollably ... at least until the lake level would fall below the level of channel coming up to the control structures. Hope that explanation helps. |

Oroville Dam's Recently Reconstructed Main Spillway Fundamentally Flawed Rumor among the locals that stopping the spill way could potentially cause damage to the levee system. Levees contact or expand depending on water levels. When the water level is high and they want to lower it. They do so over a period of time to allow levee to adjust. Levees are currently full or filling up. With the spill way stopped water levels downstream in some of the levee systems may drop dramatically with out time to adjust. Potentially comprising the levees. Don't know how accurate this is but anyone familiar with the Sacramento Valley knows how important the levee systems are. Just being in the moment. :) |

CA DWR has been trying to maintain the elevation at around 850 feet (crest elevation is 900') for flood storage. Quoting: Crunch62 Even with the previous 50K CFS releases, the lake rose almost 10 feet in the past 24 hours. With the spillway shut down, it will rise even faster. Currently at 858 feet. 42 feet to go. I'm having flashbacks to 1997, when they thought the dam was going to be overtopped by excessive inflow. It wasn't a fun time. Lived in Sacramento for years. They have some truly stupid people in charge. If I was you I'd take a vacation starting now. Pack up and move upstream for a nice camping trip. |

Oroville Dam's Recently Reconstructed Main Spillway Fundamentally Flawed They quote an official here [link to www.kcra.com] "About 200 to 300 feet of the spillway itself has eroded away, it's just gone. And that's of course of great concern," DWR information officer Doug Carlson said. "We could let the water flow down the spillway, and continue to erode the base of it. That's preferable to allowing the water to get too high in the dam." So it sounds like they are reluctant to use the emergency spout.
