Notes: 
The lake had much Potamogeton berchtoldii in the summer. This was cut and removed by the water sports centre after which the turbidity declined from Secchi 2000mm to 300mm, doubtless from a diatom bloom. At the same time three species of blue-green bacteria increased greatly. At the time of the sample, the turbidity had improved to around 600mm and the blue-greens were no longer blooming, nor had any macrophytes returned.
