Breitbart News – Northern California Snowmelt Crisis as Temps Rise into 70s
” . . . as temperatures rise to 65 degrees in mid-mountain elevations at the 6–8,000 foot levels that received 3 feet of snow in the last set of storms, 13-degree-above-average temperatures are about to trigger an early spring snowmelt,”
NOTE: Upper Feather River data and dam data links are on last Monday’ post.

Sacramento Bee –
- Can Oroville Dam’s badly damaged spillway hold up through the rainy season?
” . . . with at least five more weeks to go in California’s rainy season, and billions of gallons of water waiting to rush into the reservoir when the snowpack blanketing the Sierra Nevada melts this spring, the question on the minds of many living in the Sacramento Valley is this:
Just how long can the badly damaged spillway hold up?“
- Oroville Dam’s banged-up spillway to shut down Monday
“. . . DWR said it will begin dialing back the flows at 6:45 a.m. Monday, bringing the releases to a halt by sometime in the afternoon. DWR said it plans to keep the outflows at zero “for several days”.
Dam operators have been moving in equipment to a water channel beneath the spillway in order to remove the pile of mud, concrete and other debris that’s accumulated since the crater developed Feb. 7. The pile is backing water up into the dam’s hydro plant, making it impossible to restart.”
- This winter has bashed the heck out of California roads
LA Times – Snowpack levels surge in the Sierra Nevada, helping to power California out of drought . . . “Helping”??
San Fransisco Chronicle – Phenomenal’ California snowpack nears record depths
” . . . A greater percentage of precipitation coming in the form of rain instead of snow and irregular snow-melt cycles makes it more difficult for communities to capture water for public use.
“Instead of making its way into our faucets, the snow we have now could be washed away into the ocean . . . .””

Good film of the damage from Oroville Dam outflow –
” . . . .There are a number of dams with similar spillway problems [as Oroville], or where the inflow can exceed what you can release as outflow out of the dam and that puts them in a dangerous situation. There’s some water purveyors that are looking at new water projects that would make it even worse, like the Merced Irrigation District, which wants to raise the emergency spillway at Exchequer Dam on the Merced River so that it could store more water, but that would further reduce their ability to manage the reservoir during a flood event like this.”
This North Coast Journal blog takes issue with Breitbart News story earlier this month about the Klamath River. . . .
” . . . The Klamath Project — featuring seven dams, a series of canals and pumping stations — was designed to divert water from the river into an irrigation system that allowed for the transformation of hundreds of thousands of acres of rangeland into farmland. The Klamath River Hydroelectric Project, meanwhile, included eight dams — including the four slated for removal — and, as its name attests, was aimed to providing cheap hydroelectric power to farmers and ranchers in the area. . . “ – (Has a good map.)
We just put this video in the comments – showing the dam damage now that they turned the tap off…
