Cecil - The water does seem darker than normal and visibility is only about 4-6". In the past I have had visibility of around 12-16". There also seems to be a lot of suspended material, I assume dead coontail from the herbicide treatment almost a month ago.
It's good to hear that my meter is maybe not completely unreliable based on the reading it has been producing. One thing that is clear my early morning readings for the last few days are a massive improvement of where they were at as late as Monday morning.
