Lake Suwa is the only lake in our country in which sediment removal has been conducted consecutively for its restoration. Dredging commenced in 1969 and is still continuing. The total amount 3 of sediment dredged to date is about 1.6 million m 16 years, and the scheduled volume remaining to be dredged is about 5 million m. Although a considerable amount of material has been dredged, doubt still exists on whether the sediment removal will result in a restorative effect or not. Sediment removal, as it affects lake restoration, is our greatest concern. This paper describes our study of these effects.
