Depth that a secchi disk can be viewed from the surface - 34'.

Water is very clear today at this deep site, ties the max secchi depth over past 5 years.

Slick;

What kind of temperature variation are you reading at the thermocline? It must be extremely slight...

We use a change of at least 1 deg C per meter to define the thermocline.

9.5 m was 14.9 deg C (58.8 F) and 10.0 m was 13.5 deg C (56.3 F).

In English units that is a 2.5 deg F change in 1.6 feet, a rather sharp thermocline.
