Reither See, Austria
The Reither See is a small, natural lake situated in the centre of the tourist village Reith im Alpbachtal about 45 km east of Innsbruck (Tyrol, Austria). The lake is a popular recreational destination for residents, tourists and visitors from surrounding areas. Due to the implementation of a hypolimnetic withdrawal system combined with various measures undertaken in the 1970s, good water quality was maintained for many years allowing unrestricted recreational use. Since the early 2000’s, the lake has suffered from the growth of benthic algal mats floating on the surface.
