Sarıyar Reservoir is impounded by the dam, and provides habitat for several species of tree- and cliff-nesting waterbirds and raptors. Migrating white storks (Ciconia ciconia) roost here in large numbers. Poplars (Populus sp.) grow around the shore, and provide timber and habitat for birds and other wildlife. The reservoir is polluted by agricultural runoff and untreated waste from Ankara.^[1]
