Repairs @ Oroville Dam
Last night the town of Oroville, California was evacuated due to an emergency at the dam. Downriver – Gridley, Marysville & Yuba City were also evacuated. And the evacuation has not yet been lifted. So today, I went for a hike over at Foreman Creek, which joins the Lake Oroville Reservoir – directly east of the dam.
The waters edge is super high, coming up the paved access road and drowning the green grassy canyon and trees. A gaggle of geese greeted me and then swam away. I looked for the helicopters that were supposed to be working on the tallest dam in the nation. Nothing!
Although I did hear the crews working on the opposite side of the lake, I could not see them. I did not bring my binoculars, nor my tripod. Bummer.
I sat down on the road with my Nikon Coolpix camera and began to use the digital zoom feature, which sometimes works. I had to use my knee to balance the camera so my shots would not be blurry.
The geese decided to come back into view. With the zoom feature of my camera, I was able to make out the work vehicles that were parked on the Oroville Dam. These are the best shots of the day. Click to expand images.
On my way back to the car I started to hear helicopters, more than one – so I do know that the crews are working hard on a plan to fix the dam. All through the night 24/7, plugging the holes on the damaged spillway with rock, boulders, debris, cement, metal, whatever they can. Timing is crucial now, cuz more rain is due in later this week!
Several local creeks and 4 forks of the Feather River empty into Lake Oroville. Count ’em FOUR!
We’ve had 20 something inches of rain recently in the North Sierra Nevada mountains, so this winter is helping drought conditions in NorCal, but also putting major pressure on California’s reservoirs. Recent warm storms melted snowpack at higher elevations (Lassen), which is why the dam is currently maxed out.
Construction materials, including plastics, have come a long way since 1968. Trucks seen rolling thru town this week include: double trailer semi rigs “rock trucks”, cement trucks, and flatbeds w/ kwik bond polymers, by the ton, coming from outta state.
Oddly, DWR – Department of Water Resources, does not mention the POLYMERS, or shall we say “plastics”, in the recent news updates.
“Rock, aggregate and cement slurry are being used to repair and backfill the affected areas.” (02/17/2017)
