Of the local waters, we mainly visit Nové Košariská in Dunajská Lužná. Their biggest advantage is the depth of 40m, lots of fish and water quality. You can train in Košariská already in spring, and it is often in good diving quality until late winter. With decreasing temperature, water transparency rises and the lake reveals its bottom with a visibility of more than 25-30m. In cold winter weather, it is a pleasure to pull out a thicker neoprene wetsuit and let yourself be enchanted by the lake, which will reward you with a beautiful fish theater played by schools of crucian carp, grass carp, and bighead carp.
