Questionnaire: Assessing the potenial for cyanobacterial mass developments

This questionnaire requests limnological parameters of your water body which may be important for, or indicate, mass development of cyanobacteria.

The analysis of parameters influencing cyanobacterial mass development is a complex task for which several limnological parameters need to be considered and assessed. It should also be considered that any changes of these parameters may have an influence on the potential for mass developments.

More information can be found under catchment and water body.

The concentration of total phosphorus (TP) between May and October is:


Is the water body stratified?


What is the retention time of the water body?


What is the pH of the water body?


Secchi depth from May to October is usually
