Description
The large open water surface of the reservoir and the little amount of disturbance during wintertime attracts thousands of wintering waterbirds, making the area one of the best places in North Rhine-Westphalia to look for ducks etc. potáplice malá, potáplice severní, potápka žlutorohá, potápka rudokrká, morčák prostřední, morčák malý, polák kaholka, turpan hnědý and turpan černý are recorded regularly (but not annually), besides high numbers of the more common species like polák velký, polák chocholačka, hohol severní, morčák velký, potápka roháč and potápka malá. The rivers that feed and exit the lake are holding several breeding pairs of skorec vodní, ledňáček říční and konipas horský. The surrounding forests are also interesting, where some territories of žluna šedá can be found. With low water levels in late summer and autumn, the resulting mudflats become attractive for migrating waders, like jespák obecný, pisík obecný, vodouš šedý, kulík říční and kulík písečný.

Access
There are several (mostly paid) parking possibilities around the lake. Considering the size of the lake it's best to take the road around the lake by car and stop at interesting lookout places, e.g. the dam in the northwest corner or the bridges. The southern part of the lake is not accessible by car, it's possible to park the car and explore the shore by foot or bike.
