Pidjanga notes: Indeed, at 219.35 meters maximum depth and 122.48 meters mean depth, Tumanda et.al (2005) confirmed that Lake Mainit is the deepest lake in the Philippines. The study says that the mean depth is a reliable morphometric indicator of trophic conditions of the lake with mean depth inversely related to production. It adds that shallow lakes are more productive than deep lakes. Lake Mainit is considered a deep tropical lake hence its water volume available for biological productivity is quite small.
Sige lamang... scientific facts like this are of great importance for planning. Let's hope that brilliant Mainitnon minds (or that of Lake Mainit communities) can find some ways to make the above fact bring positive developments to our beloved lake. We'd appreciate your comments and suggestions.
Anay pa... have you noticed the deepest parts of the lake? An mga kantil jaon banda sa south- west part. An study nila Prof. Tumanda (2005) nagsuporta na kun hain an baybay na wayay mga river tributaries, jaon an mga lagyom na parte nan danaw... jaon sa area nan Malimono range. An baybay na suod s Mayag River (northwest), sa Suba nan Mainit (north), sanan Magpayang River (northeast), mga mabaw.

Update: In early 2012, I discovered that at 600+ meters, Mount Pinatubo Crater Lake became the deepest lake of the country.
