Pond & lake management
Lakes and ponds often suffer from eutrophication. In principle, bodies of water are categorised into trophic levels. With increasing nutrient pollution, a distinction is made between
1) Oligotrophic (low nutrient content and low biomass production)
2) Mesotrophic (transitional phase)
3) Eutrophic (high nutrient content and high biomass production)
4) Hypertrophic (very high nutrient content)
The last stage is also referred to as “overturned”, as fish mortality is often observed in this stage due to extreme oxygen depletion.
Here is an OLOID Type 400 in the Kynastteich pond in Berlin. Nice to see that the pond is kept ice-free
