Talk:List of rivers and estuaries in Metro Manila

How complete should this list be?
I was just wondering at what point a waterway becomes too minor for mention here. There are other names that could be listed here. First off the top of my head (though not necessarily more important/significant): Culiat Creek in Diliman (Eventually emptying into the San Juan River) or the Calamiong Creek in Barangay Bagong Silang (Eventually emptying into the Marikina River) in Quezon City. Or Nangka River in Nangka (Empties into the Marikina River)or Bangkaan Creek in Parang (Eventually drains into Manggahan floodway) in Marikina. Should these be added too? - Alternativity (talk) 17:03, 15 March 2013 (UTC)
