I do not have any kind of calibrated measure of clarity, but it does vary with time. Sometimes the clarity is very high, but other times it is much less clear. In general, I can see bottom at about 2 feet, but sometimes its more like 5 feet (not typical - usually during colder season). At other times, the water clarity can be very very low (heat of summer with little rain). I know that this is probably too vague to be of any use to you, but that's what I have in terms of info.
