Lake Onneto has been classified as an acid lake since 1985; however, our latest investigation in 2013 revealed neutralization of the lake. Additionally, previous studies revealed that the neutralization occurred between 2008 and 2012. Water chemistry data generated in the present study implied that the neutralization occurred because of decreased flux from an acid inflowing river, increased flux from a slightly alkaline inflowing river, or a combination of these factors.
