| Changing shoreline of Akanoi
Bay |
| The lake bottom relics at Akanoi Bay which trace back to 6,000 years ago
indicate the portion now under water was once a land where people lived
in the Jomon Era(10,000B.C. - 400B.C.). Lake Biwa collects and stores water from the rainfall in the prefecture and discharges it only through the Seta River. This caused submergence of fields due to torrential rainfalls to continue. The completion of dredging work of the Seta River in 1911 thanks to the
petition made by the residents along the shore finally terminated large-scale
damages. The shoreline at Akanoi Bay has not altered very much since the installation
of Nango Dam at the Seta River. |
