Nirnroot in Oblivion, Where to find it?

[Energize]

I have been to that copse place but I still only have 5 roots when I need 10 for that elixer, I know that it grows near water in the great forest and some nearby caves but I haven't found anymore yet, any hints?

And is it just me or are the elderscrolls forums down nearly all the time, or extremly slow?

Ok with some help from the elderscrolls forums, I got 10 then he gave me the potion, then I gathered another 20 to make the moderate potion, now he needs 30 more for the strong poition, arggh.
