Plants : lucious growth gutweed (darmwier) which seems to be more abundant then Elodea (Waterpest) Measured one curly pondweed = 2,60 mtrs high.
Spotted a Sinantherina which in Dutch is called Raderdiertjes. This little white globe is attached to a waterplant. I have never noticed this before in hbos. It is about 5-7 mm. See photo's which unfortunately are super sharp.
Visibility  : 5.0 mtr at 6 mtr depth at reel
Yellow viz: no readings.

The thermocline is still at 16,5 mtr depth with a milky layer underneath it.
Since the Southwest pump started the watertemperature is pretty constant from surface to 16 mtrs depth. 
A lot of swampgas is emerging from the bottom more them usual.
