Those are grouped into four types: 1) relative comparison of water level at peak between extreme floods, 2) observation records of water level using scaled posts, 3) inundation depth records of house, garden or rice field and 4) records on daily variation of flood level. In this paper, we picked up and collected historical records on water level of Lake Biwa from old documents, and attempted to represent daily water level data in Biwako Standard Level (B.S.L.) for three historical extreme floods at the end of Edo Era. Moreover, we reconstructed the water level at peak for other historical floods for about 150 years by estimating the standard level of Feudal Zeze Clan., application/pdf}, pages = {371--376}, title = {古記録による琵琶湖歴史洪水の水位推定}, volume = {44}, year = {2000}, yomi = {ショウ, ケンジロウ and トミナガ, アキヒロ} }
