The reservoir is laid out like a swimming pool, shallow water, for the little ones at the beginning of the lake, at the end about 180cm for the big ones. There are also entry and exit options like in a swimming pool. Around the lake there are very nice lawns and a playground for the little ones - REALLY TOP!
