LA Water Supply in Danger From the Station Fire?
I've been monitoring the LA Station Fire from afar these past days (week or so), its amazing what one can "see" from the Internet with a little GoogleEarth and Weather Underground (www.WunderGround.com ). Those of us with a bent toward earth science in the modern times watch these things. Year over year drought, watershed over-taxing, and coupled to mass urban sprawl, and all...
Once the threat to the sub-divisions just east and over the mountains from Burbank subsided, its amazing how fast The Today Show and company pulled up camp and moved on to better ratings generating subject material. The human tragedy stories from the Middle East sure pull on the American heart strings, especially the ones about women's rights. Yes, it does make one feel good to know the heart warming stories covered by our US media from half way around the globe ratings trump anything going on locally. Well. Unless its the once in a life time (each) ratings opportunity of a Michael Jackson or Ted Kennedy funeral.
The threat to Mt Wilson science and communication facilities did garner some mention.
As I watched the fire progress on the southern-eastern flanks, it became apparent to me the lack of access and rugged terrain made for a kind of perfect storm as the fire progressed with not too much to stop it, short of Mother Nature helping soon. Gotta love the rains, if they come. Or maybe not.
As the fire approached the Cogswell Reservoir, it also became apparent to me the potential mud slides that could follow later might very well endanger the reservoir. Then, with a little closer research I learned that Cogswell is but one of three resevoirs in the system, followed by many other flood control and water supply "constructions by man" that all together make up a big part of the greater LA social safety and civil foundation infrastructure.
And then the fire hopped right past Cogswell, and is now heading toward the San Gabriel Reservoir.
The www.Inciweb.org site finally came out and acknowledged the Angeles Forest watershed accounts for a full 35% of the LA water supply, and yes, there is and are real threats to mud slides from unstable burnt forest areas once this is all over.
(That mountainous rugged and scenic ground is thin topsoil on top of rock. The water doesn't soak in so well to start with, after removing the vegetation by fire it can be a bit of a water supply / flood control problem if all that soil moves down hill and into the reservoirs)
Hmmm...
That sounds like news worth covering, but it isn't on the TV or the web. Not being covered at all from what I can tell.
Let me see, 35% of the LA water supply may became threatened, and flood control may be threatened, and the news isn't on to it yet.
Is Homeland Security?
The Green Jobs guy did resign and the President will be speaking on healthcare. Again. Is he "on top of it" ? Are his people?
How about the folks in LA, will any one mention it to them any time soon?

I live in Northern California, and I we have had many fires the last two years and very little water, so I understand your fears as being real in socal and also here in the north. I read that El Nino is developing for this winter which will bring with it rain and the dangers, like you say, of mudslides and flooding.
NOAA scientists today [July 9, 2009] announced the arrival of El Niño, a climate phenomenon with a significant influence on global weather, ocean conditions and marine fisheries. El Niño, the periodic warming of central and eastern tropical Pacific waters, occurs on average every two to five years and typically lasts about 12 months. See NOAA Press Release
El Niño conditions, which are foreshadowed by warming Pacific Ocean temperatures, are often associated in California with destructive storms, flooding, mudslides and power outages. However, a moderate El Niño can often bring normal or below-normal rainfall to the state, experts say. "Right now, most of the models are trending into the moderate range," said Jan Null, a longtime meteorology consultant based in Saratoga. "If you look at past moderate events here in Northern and Central California, it's a toss-up in terms of precipitation."

It would seem to me, the Fire Service / Homeland Security folks would be looking at preventing the fire from continuing thru the San Gabriel watershed as a bit of a National Security issue... considering the potential consequences. Where is the news coverage?
Thanks for sharing your views.
