Thanks both of you. On 7/31 Dave asked me to do such a test and I did. In the years past, I had learned from PB articles how to make such a device and conduct the test, although deciding when to say " no longer can see it" is kinda a subjective thing, and I have noticed that it is different from person to person, as I had uh..er.. um..ok YOUNGER and stronger eyes help me with the test on a couple of occasions. Some of the young folks must be our snipers we hear about occasionally.....sure have a great set of eyes! Others....well, I sure hope they are not on the road the same day we are driving to my Drs appointment! I know I can't drive worth a hoot while napping, and I am reasonably sure some of them can't see any better behind the wheel wide awake than I could snoozing! Sorry, drifted off topic again, just like the Chevy did
At any rate, I will do as you ask, and will gather up a water sample at the same time to ship off to the lab for testing. I am sure there is a lot information available right here within these forums to help me interpret the results I get back from the lab, which will no doubt look like Klingon to me at first....
I know this is probably of extremely limited value, but there is one picture in that cluster I posted of a pretty good size tree stump that had been cut down just before the new pond was dug, and although not white and a little smaller than the secchi disk will be, is only under 4 inches of water, in one of the clearer sections, and is not easily seen considering the size and depth of it. However, I realize it is no substitute for the proper tool.
Thanks for the pics and the links guys, everything I can get I try to put my mind to work and soak it all up like a sponge. Unfortunately, like a sponge, it seems like the more I use it, the more difficult it is becoming to get the job done properly!
I will be back when I have that stuff for all of you. Thanks again. You all are certainly a patient and forgiving bunch
