Okay, good morning everyone. As one who has followed this event with interest it looks like Oroville is still holding on this morning.

Based upon Lake measurements, it appears inflow has fluctuated between 47k and 23k cubic feet per second. Operators have been holding outflow over the main spillway to 59,900 cfs or thereabouts. This has kept lake levels falling very slightly from 851.17 to 849.54 or a decline of 1’ 7 1/2”.

Rainfall in the tributary area continues with Brush Creek, Four Trees and Buck’s Lake showing 24 hour rainfall running 2.4, 2.7 and 2.9 on the main fork of the Feather. Quincy and Grizzly Ridge have received about 1.5 inches. Gauges at Buck’s Creek and Lake Davis are not reporting data but areas surrounding them are less than critical.

Beale AFB radar:

Shows the more intense storms in the Folsom Reservoir drainage but higher elevation hills shade out some readings east of Oroville.

Clicking the eastern link shows Reno radar showing even distribution of precipitation across the western Sierras.

San Francisco Bay radar
https://radar.weather.gov/radar_lite.php?rid=mux&product=N0R&loop=yes

Shows the storms making landfall to be heavier south of the main urban area with Flash Flood warnings south of Monterrey Bay. I believe the coast highway is still closed for the bridge problems at Pfeiffer Canyon so travel there is very limited.

A prayer is offered for the next 72 hours that the Rivers don’t rise and the dam holds.

it’s not raining hard enough for significant flooding.
