Where are the foul water fishing holes in Grahtwood?

Magnificat

I need the Bilious Catfish and the two eels to complete the Grahtwood Angler fishing achievement but I can't find any foul water, sewer, or swamp fishing holes. Please help. Thanks.

There are a few small pools NE and NW of the Elden Root and there are also nasty streams around the hollow tree to the west.

Edit: also the swamp SE of the Ossuary Wayshrine
