Which facts must be known?
- in situ quality of water body (depth distribution)
- thermal structure of stratification
- Selection of extraction level of raw water to a level of minimal
iron and manganese concentration (usually upper hypolimnic drainage)
- Draining of deep water rich in iron, manganese, phosphorus out of
the reservoir ore the lake (according to quantity of inflow and the requirement)
