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.
