Pond Boss Forums POND CONSTRUCTION Selecting a site Quarry Contest 2010

I took the sample in a cove that is on Lake Dardanelle. This lake is part of the Arkansas River. The cove is usually clearer then the channel but today there wasn't much difference. The secchi depth was 40 cm.

Turbidity values are given as NTU's with zero being the lowest value. The surface water had a value of 22.5 NTU's. The water at 2 meters had a value of 22.7 NTU's. The depth was 4 meters so I dropped the sample collector all the way to the bottom and then pulled it up a foot. I got a value of 27.1 NTU's. Some sediment may have been stirred up but I am pretty sure that is an accurate reading.

Interesting. I'm assuming that the lower the number, the clearer the water is. Are the NTU values linear? i.e. if 22.5 NTU's = 40 cm, 22.7 NTU's = how many CM? Thanks for taking the time.

Yes, the clearer the water the lower the value. I believe the values are exponential. I made a graph a couple years ago comparing secchi depth and turbidity. If I can find it I will post it.

Here are some other values from today.

Secchi- 90, Turbidity 11.6
Secchi- 35, turbidity 36.7

It's now the two minute warning.

I'm computing scores, and we'll have two more good questions.

By the way, I was watching ESPN tonight and they posted the following score...

Secchi 90, Turbidity 11.6

Evidently Turbidity's home field advantage ain't what it used to be. I don't know if you guys knew this, but I was offered a partial scholarship to Secchi for curling.

But you obviously missed the fact that this was a double header and Turbidity squeaked out the win in game 2!

Very impressive about the curling bit - I know you've been parked in front of the Olympics just thinking about what could have been!

I thought your scholarship was in bowling? Or was it for miming?

---- ----- And all that time I thought it was for Nebraska Volleyball !

That might have been the culmination of a dream. Me, playing outside hitter for the Husker volleyball team. I would have even gotten my own locker room!

One thinks you would have been happy to share.

Wow, I had heard that rumor at the last Pond Boss conference but I just assumed it was a nasty rumor designed to impeach your character.

I had also heard that Sunil was awarded a scholarship for 12 ounce curling and this I found very believable.

The scholarship was for grad school, JHAP.

I developed and honed my curling technique in undergrad. Maybe that's why I never went on to do post-graduate work.

DIED = 30 1/4
Todd3138 = 23 1/2
ewest = 19 1/2
CJBS = 15
essup = 14
DD1 = 11
Omaha = 9
Youngblood = 8
Greg Grimes = 7
Burgermeister = 5
Dwight = 2.1
blair5002 = 2
JHAP = 1 11/16
Yolkie = 1 9/16
Sunil = 1 7/16

Question #8 is just a little one pointer during the two-minute warning.

I tested the pH of the water. Was it above, or below 7?

Above

Right On, I'm in third place! (from the bottom)



Insufficient information. In order to narrow down my thought process, allow me to make some intuitive inquiries. Did the air smell of pine? Was it a cloudy or sunny day? Were the winds out of the southwest? Did the water taste of elderberries? What was the reading on the pH meter? Why is the H in pH capitalized? Is your pH meter an American meter or a metric meter? (I know your proclivity for all things metric). What color is your meter, white, black, pink?

If the quarry is an old limestone quarry, I would say above... Lots of buffering power there. Plus, most soils in Nebraska are alkaline. That why honey locust does so well there and the ponds tend to be naturally fertile. Bruce also mentioned their being lots of crayfish with the CC being packed full of them at times. Crayfish tend not to do well in acidic waters.

I'm going with above due to it being a limestone pit.

Upon careful review of your responses my answer is


Thursday.

Nothing? Not even a twitter?

Tough sub.

Coincidence? I think not!!
Alright, Condello, fess up: What have you got against Peroni drinkers?

"Bruce, I AM YOUR FATHER. Well, actually, no, I can't back that up."

Don't get me started - my kids aren't old enough to watch the Austin Powers flicks, but they pretty much know every line because I'm one of those freaks who believes that EVERY conversation in life can be handled with Austin Powers references!

"Alright, Condello, fess up: What have you got against Peroni drinkers?"

Yeah!

Actually I did quite literally laugh out loud to your responses.

After posting here this morning, I had a tax appointment. You know tax clients find it rather un-nerving when their CPA is giggling during the tax interview.

I have another appointment in about a hour. Hopefully I shall be able to exhibit a moderate amount decorum during my second appointment of the day. Or not. We'll see.
