One of these days I am going to set up the camera so I can take pics. from it as has that feature.


Theo :

Our water is clearer now than last summer but not than 11-05 when last I took water temps. Absent fert. program our water looks like bottled water from the store. At depths below light penetration it is always clear unless a huge rain event. Our temps. are 6+- degrees colder than others in the area during warm mths. During other temp. surveys there is suspended ( I assume plankton type) matter but never has it been fluorescent. My wag is that it is some kind of winter zoo/phyto plankton.
