High levels of E. coli in Shadow Cliffs causes partial closure

East Bay Park Regional District expects closing to be temporary

The south beach of Shadow Cliffs Lake closed Wednesday afternoon due to an extremely high E. coli bacteria measurement, according to the East Bay Regional Park District website.

Alameda County Environmental Health Department recommended the closure, stated the website.

According to EBRPD water management Supervisor Hal MacLean, the district sampled water Thursday afternoon and results should be ready by noon Friday.

Water samples will be taken daily until it is safe to reopen, which the district says should be in the next several days.

"Shadow Cliffs' water usually gets higher (E. coli) readings in the summer," said MacLean. "But the south beach's level spiked really high."

MacLean added that some of the contributions to the high readings could be the low water level, as well as not watering the lawn.

"We haven't been watering the lawn to conserve water," he said. "So instead of the geese congregating on the lawn, they're congregating on the beach."

The EBRPD website has provided the public with a rating system of the water quality.

The north beach, left of the lifeguard chair, is currently open with a "Yellow Light" water quality rating -- which means there is an increased health risk for swimming and wading, and bacteria results do not meet State Health Standards.

Sheryl Chance wasn't aware of the high readings of E. coli Thursday afternoon when she took her grandchildren to swim at the north beach. With no hesitation, she quickly told her grandchildren they couldn't swim.

"It's bacteria," she said. "I don't want them swimming in it. I wouldn't swim in it."

The daily maximum of the State's water quality bacteria level is 235. As of Tuesday, south beach's bacteria level was 24000 and north beach 680.

As the amount of low-cost housing increases in the Tri-Valley, look for this problem of doing #2, or not washing after doing #2, to become more of a problem at Shadow Cliffs. I'm not saying that lightly, but from years of observation of the phenomenon in other areas.

You can have a Shadow Cliffs in your own backyard. Order up a stock tank from your closest Livermore hardware store. Fill it with water in December, and spread bread around to attract as many ducks as you can. Let it bake in the sun, and for pete's sake don't put any chlorine or new water in. Just let it sit...nice and stagnant. When the water level has evaporated by half, the water turns black, and the tadpoles start to die, you've got it! Just like Shadow Cliffs! 30 years here, and I still haven't met anyone in town who has actually gone swimming there.

We live in Ptown (and not in low cost housing) and take our boys to Shadow Cliffs a few times every spring and summer, although I haven't had the chance to take them there this year since the water rationing.

Very few of our Ptown friends have taken their kids there. I try not to pass judgment on people based on their appearance, at least not in a setting like a public park (how someone presents themselves in a job interview is a different story). Having said that, I don't think most of the people there are Pleasanton residents and from the style of tattoos I see there (those letters in cursive across their chests and backs) many appear to be from a lower economic background.

But I don't care how much money the other park goers make and my kids certainly don't notice. We're all part of the human race, no matter how much money we make, and I'm doing my best to make sure my kids don't grow up classist (having negative opinions of people and applying stereotypes to them just because they make less money). Classism isn't as bad in the US, in my opinion, as it is in other countries. I especially noticed it when I lived in South America for awhile.

I do worry about the E. coli but I know they monitor the levels daily and trust they have adequate controls to shut down the park when the levels are bad. From scanning Yelp it looks like they have had a few incidents of swimmer's rash from around July 2012, but I only see one E. Coli incident and it was someone who was immuno-compromised.

I'd imagine they don't monitor E. coli levels as fervently on airplanes, and it looks like that's a much bigger breeding ground for this sort of stuff:

Peace and love. Personally I'm glad we have a Shadow Cliffs in Pleasanton. Del Valle is always another option and much more enjoyable to get to if you take your bicycle!

Pete, you're so right on, although your political correctness is a little much. Just spell it out:
On weekends, it looks like the border near El Paso, with the MS 13 cholos drinking cheap wine and waiting for inevitable fight to break out with their homies and/or their wives (per the details on the police blotters).
And they say the E.coli is from too much bird droppings.....

Cholo, I think the PW moderators are growing tired of censoring your posts.

Usually, they elaborate their reasons in more detail (post makes no sense, post makes personal attacks or unverified claims about an individual, post has nothing to do with the topic, etc.). Now, it's just down to 'removed'. LOL. They say brevity is the soul of any case, we get the message...everyone is tired of your act. Rest your case already.

Yes, Cholo, as the editors so often illustrate, they are much more concerned with your humor than the racist sewage spewed by Disease/Right/William Tell/Pleas-was-nice-40/etc.

I guess PW editors are afraid their readers will be offended by harmless off-the-wall humor, but will feel rather comfortably at ease with racist rants from hating spewing KKKers. Such is the town we live in! Thanks PW for clarifying our demographics and the biases that extend from it.

Censor, from 'another neighborhood': You still live in a once free country. Feel free to not read these posts, stay away from the PW, or move away from the area you find so offensive.
Harmless-off-the-wall humor? So, you think advocating for La Raza-type takeovers of our country are acceptable? How about the constant anti-white rants threatening takeover of ove rneighborhoods that are 'inevitable'?
You and your ilk may find this drivel and his veiled threats 'humorous', but you are 'in the minority'.

Find a worthwhile cause to defend, or move on.

(Removed) I'm all for freedom of speech -- even your own racist sewage. What I'm criticizing is PW censors' practice of censoring Cholo and others they disagree with while leaving alone the hate-based, racist venom that they seem to believe represents a substantial segment of their readership.

La Raza? Takeovers? Really. What are you afraid of you frightened, hate-filled, little man?

You might find more tolerant uptake from others over on Cushing's blog. He feels comfortable letting the racists have their say because, hey, Republicans deserve our respect, even the racist ones (who are a majority of the party). Also, of course, hatred and hate-selected lies and misinformation is pretty easily refuted, and so you'll feed Cushing's comfort level. It is anyone to the left of himself who he truly fears, their arguments and facts threatening his faux liberalism. (See his censorship of Stephen Colbert; see his obsession with knowing and filing people's IP numbers.)

Troll with a man crush for Cushing. How very diverse of you. Maybe now might be a good time for mr. Cushing to get a restraining order.
