Kevin,

Did they measure pH on your water sample?

Also, your turbidity is measured in NTU (which is hitting the sample with a light beam in the lab). It is very accurate, but not that useful for you to monitor your pond over the year.

I would recommend you buy or make a secchi disk to help you monitor turbidity in your pond. (Do a google search for how they work.)

Take a secchi disk reading when the water looks similar to the day you took your water sample. You will then have a rough calibration to use if you ever get another lab measurement of turbidity in the future.

Congratulations on your new pond. I look forward to reading about how you and your son turn it into a good fishing hole!
