We were curious about silt buildup in Jameson Lake from the deluge on the Thomas Fire burn area. As we climbed up to fly over the flood area we got this pic of it, and one of the catch basin above Carpinteria. There's somewhat of a catch basin above the North bank of Jameson, but it had already been silted up before the fire so I was surprised the lake didn't look much different. It's presumably lost capacity though, due to silt from the entire watershed above it being burnt bare. The catch basin at the North end of Santa Monica Creek above Carp caught a lot of boulders and debris. I'll also post a pic of the smaller catch basin in Toro Canyon on SBitZ.NET and both of those probably saved many homes downstream because the downpour was relatively brief.

The need to blame seems endemic to people who post on these sites. Please stop blaming the victims and stop blaming the civil servants and stop blaming historical precedent. If you want to blame something point the finger at "fate" or "gods" and move on to a more positive effort.

Thanks for the CalOES link. I've added it to SBitZ.NET along with a link to the CalOES website and bookmarked both in my browser for future reference. Thanks for the repost and kind words TwoScoops, and for giving me an extra nudge to start new Topics on SBitZ.NET so the pix aren't all in one monster Topic. Somehow I hadn't noticed how that bogs down the loading for anyone visiting SBitZ.NET for the first time. When I go there as a new visitor, sometimes it takes a reload before a big Topic will start to display. Once (if!) things settle down, I'd like to find another free medium for SBitZ.NET but right now I still have lots of pix to review on top of everything else going on. Glad we have Edhat! :)

John, I'm posting the link to your photos. https://groups.google.com/forum/#!topic/sbitz/Al4MloLl1Xs. Thank you for keeping this blog going with so many photos of the debris flow damaged areas of Montecito.

Cal OES video from Thurs. Jan. 11 has an inside the search and rescue operation: https://www.youtube.com/watch?v=QlgQPK-1bL8. John, There are drone and helicopter flyovers. Take a look at 8:45, ""During a wildfire, burning plants release gas, and that gas permeates into the soil causing the roots to weaken. The gas then pools and solidifies, forming a waxlike layer at the surface. Unable to permeate the ground, the rain then begins to saturate and weaken the topsoil above that waxy layer. As more rain falls, chunks of topsoil break loose and slide down the slope. Rocks, trees, and mud flow freely and can exceed 35 mph. Left behind, a thick water resistant layer that can last for years, based on intensity of the fire."

I'd guess Burbank was not here in beginning and although I may have not driven every road out there that one didn't look familiar. My question is did they survive....that had to be one scary ride.

EASTBEACH... I didn't say the victims were being blame ON THIS THREAD. It was in the video that they harped several times about victims not doing what they were told... ie, when warned to evacuate (as I was though I live many miles away). What I am suggesting is more compassion for the victims and less "I told you so's" as expressed in the video.

OCEANDREW - if you're referring to the cell phone warnings, they were issued by SB County's OEM (Office of Emergency Management) not CalOES (California Office of Emergency Services). In addition, the OEM messages directed you to refer to the county's website to determine if you were in an affected area (did you follow instructions?). Finally, nobody is blaming victims in this thread.

The CalOES video is very interesting, thanks for posting. I googled and found that soil mechanism is called "hydrophobicity". Seeing things from the perspective of people on the ground was interesting since most of us aren't allowed into the area. The clips of the debris flows captures something most people will never get to see in person (wonder if the clip from the Burbank Firefighters @9:55 showing the car racing the mud flow was local or some other event?). Didn't know Reilly the rescue dog barks while working.

According to CalOES I should've evacuated because I got the warning ... even though I live well away from any burn scars (Turnpike @ SR192). I'm sorry but this constant blaming of the victims is reprehensible.
