I saw this sign at 3rd today and called the number - apparently there's a bacterial contamination that can lead to flu-like symptoms. Has anybody gotten sick?

There doesn't seem to be any up-to-date SF Bay water quality information online, but I came across an interesting, but worrying article on maintaining water quality in the Delta: Record Drought Could Hurt Water Quality. Sounds like we're in for a Microcystis algae bloom at Sherman, has this been a problem in the past?

I also came across this interesting fact: 150 years ago, hydraulic gold mining in the Sierra Nevada caused a silt buildup in the Bay that is only now starting to clear! (Does this mean an end to low tide mud baths at 3rd?)

Thanks for the post. I was out on Sunday & have not had any ill symptoms. I launched from the upper, so didn't see any signage. This did promote some self education on water quality I'll share.

SMC tests 43 sites each week & reports the high indicated warning locations to this site:

There is also a map with more detailed data available:

Here's the available data from 3rd Ave (Kiteboard Beach)

Warnings are issued-
when single samples exceed 10,000 Total Coliform, 400 E. coli, or 104 Enterococci, 
or when a 5-week geometric mean exceeds 1,000 Total Coliform, 200 E. coli or 35 Enterococci.

As someone who knows very little about this, I'm guessing these high levels are due to the recent rains. Also interesting to note that the tested areas around 3rd Ave; Coyote Pt., Aquatic Park, etc. had exponentially higher contamination readings.

Wow, that is really disturbing. I think I swallowed some water out there Monday, but my skin hasn't turned glowing green yet, or whatever e-coli does.

Does anyone know who puts up the sign? We did see it when we left, but I definitely wouldn't have kited if I knew ahead of time. Maybe we could ask whoever puts it up to send us a note, so we can post it on this forum. I usually read this about once a day or so, and I assume other people do, so it would actually go a long way to get the word out.

Friggin Old Guy needs to get his catheter check out again. That might explain the 2/10 spike.

I rode with FOG on coast today. I can pretty much assure you, 3rd Ave isn't a place he frequents, catheter or no...

Kirk out
