Talk:List of rivers of the Philippines

Longest river in PH
Many websites show that the Cagayan River is the longest river in the Philippines, often indicating that it is over 500 km long. But most of these websites are either wikis or blogs or otherwise non-authoritative (i.e. some travel website without proper references). I couldn't find any reliable source (other than EB) for PH river lengths. Therefore, until someone can provide reliable and authoritative sources showing otherwise, I will use the EB references that indicate that the Agusan River is the longest. -- P 1 9 9 ✉ 17:50, 8 May 2017 (UTC)

While I have my doubts about how authoritative this website is, by lack of any alternatives I will use this to update the articles until a better source is found. --  P 1 9 9  ✉ 14:16, 6 September 2019 (UTC)
