Restoration of Hayazaki Inland Lake (Nagahama City, Shiga Prefecture)

Inland lakes have diversified functions represented by natural ecosystem maintenance and water quality improvement. Hayazaki Inland Lake, which contacts Biwa Lake, was once the largest spawning ground of endemic carassius cuvieri in Biwa Lake, where precious plants including vallisneria natans and brambles were grown and aquatic birds such as tachybaptus ruficollis and resident birds lived. However, the area has been shrunk by agricultural land reclamation. Also the disappearing waterfront ecotone due to the construction of the dike on the lakeside is affecting the growth of various indigenous organisms.
For this reason, Hayazaki Inland Lake Restoration Project was inaugurated as a leading-edge project to conserve the Biwa Lake ecosystem. Since 2001, regeneration of the inland lake by flooding an area of 17 ha out of the 89 ha reclaimed agricultural land has been studied.
