Provincial nature reserve
Located in the catchment basin of the Fersina torrent, near the village of Brazzanighe, not far from Pergine Valsugana, it consists of a small lake with a surface area of approximately one hectare, 160 m long and 100 m wide.
The modest extension of the stretch of water, together with the reduced depth of the reservoir (a maximum of two metres) make this wetland more like a pond than a real lake.
The Reserve is also a Special Area of Conservation and is one of the protected areas that make up the Brenta River Reserve Network.
