Turnover in stratified lakes and reservoirs may lead to water quality problems (i.e. low dissolved oxygen levels) especially in eutrophic water bodies, impacting ecosystem sustainability, recreational services, fish farming and food security

– In Turkey, fish farming contributes about one billion TL to economy

– 575 millions of small fish have been introduced into selected ponds and dam reservoirs

– Yet, fish deaths are observed due to turnover as well as other factors

There is a need to develop a system that would go beyond monitoring and warning. Turnover can occur within hours and fish deaths can be observed within few days.Technological advances, simulation and IT technologies can help to minimize the impacts of a turnover event through real-time monitoring, prediction, and autonomous emergency action.

Lake Eymir is the study site where hundred thousands of fish died during turnovers.
