Abstract
Eutrophication of reservoirs can be detected by changes in the abundance of insect and crustacean remains in the sediments. In recently constructed reservoirs, the time of impoundment can be determined through the presence of chironomid head capsules. The initial phase is characterised by highly enriched water as can be seen by the abundance of Bosmina remains. If further nutrient input into the reservoir remains low, the upper part of the sediment column is almost completely lacking in invertebrate remains.
