The largest dam built in Bulgaria since the mid 80s onwards, is The Tsankov Kamak Dam. Located near the village of Mihalkovo, the dam is part of the Dospat-Vacha Water Cascade. The dam collects water by rivers Vacha and Gashnya, and its volume is 111 thousand cubic meters of water. The shores of the lake are very steep and inaccessible, its altitude is about 680 m. The water mirror of the reservoir reaches Devin and its length is about 15 kilometers.
Besides large-scale hydro facility, it is also a favorite tourist attraction in the Western Rhodopes, mainly due to the wonderful fishing opportunities and attractive boat trips that can be organized in the lake. Boats and water wheels are equipped with life jackets and meet all safety standards.
