Problem with Iron Lake Spearing

[Qfox]

I was trying to get the achievement of Spearing G5 @ Iron lake
but i face big problem, which is the spot for spearing ...
if anyone have experience in gathering will understand this thing
u need to circle around 3 different spot before repeating it again, and sometime u don't have enough spots for spearing/harvesting/Quarrying ~ so we attempt full deposit to get rotation of reset system. but in Iron lake was only 2 spot for spearing .. and no fish schools around to help me reset it. i wish either SE add fish school or add 1 more spot for spearing .. because this G5 Spearing achievement its seems impossible to do with this condition.

I believe if you just catch one fish from the lake, it'll count as using a spot.

dont catch any fish, just pole in the water and out, or catch all the fish, has to be as a school.
