75 m² riffle-pools, outdoor

A total of 40 outdoor ponds with a flow-pool structure are located at the station. There are 16 bigger ponds with a 30 m long stream section and 45 m2 pond in the middle, respectively. The ponds have a variety of solutions for adjusting incoming flow, water depth, and bed structure, and for incorporating automated fish monitoring systems. The ponds support benthic invertebrate communities, thus enabling a natural food supply. The flow-pool ponds are excellent for study designs that need adjacent near-natural stream and pool conditions.
