The Derveni Info news site published images from the dried out canal of the St. Petka dam in Matka. The dam, one of the three on the Treska river, has almost no water flowing from it, which can have very negative consequences for the fish and other wildlife along the canyon.

This is likely the result of the unusually warm and dry autumn. The first serious rains of the season are falling only now, in late November, which has negative consequences for water levels across Macedonia.
