Sprotbrough Flash is one of the richest wildlife sites in South Yorkshire. A mosaic of open water, wetland, woodland and limestone grassland. On the north bank of the River Don it is named after its main feature, a long, water-filled depression parallel to the river. It overlaps with Sprotbrough Gorge, a Site of Special Scientific Interest. YWT is 28 hectares.

magnesian limestone has been mined since the mid-19th century. Mining has since stopped and wildlife has returned to this area. The original quarry can still be seen opposite the River Don, adjacent to the Sprotbrough Flash lake.The long lake from which the name of the reserve is derived is the result of subsidence caused by the collapse of old coal mines.

Wildlife includes common kingfishers, brown hare, grass snakes, Eurasian bitterns, ruddy darters, and the great crested grebe. Plant life includes common twayblade, common spotted orchid, spindle, small leaved lime, woodruff, greater stitchwort, sanicle, and the early purple orchid.
