As a locale for birds, the lake was significantly deteriorated by the mid-1970s drudging which caused a colony of black-headed gull to disappear. Today, the lake has a regular presence of mallard, Eurasian coot, great crested grebe, common goldeneye; regular visits of common gull, heron, common merganser, osprey, marsh warbler, great reed-warbler, and grasshopper warbler; and some uncommon guests such as common kingfisher and black-throated diver; the lake itself thus still being of ornithological interest, while the forests surrounding the lake attracts long-tailed tit and lesser spotted woodpecker.
