factors affecting water clarity MN

[DiverQueen]

Yes, Southern MN does have more farms, I grew up in that area.  One lake where we used to swim when I was a mere polliwog had NO VIS.  I was in there snorkeling two years ago and you could actually see bottom at 3+ feet.  What else has changed??  The have installed septic systems and upgraded old ones!  (Please don't tell me what I was swimming in!  : )

I thought algae was anaerobic (That's what my brother used to tell me anyway).  Add oxygen to the water and it reduces the algae bloom?!?!  Well, it didn't work in the pool either.  Where can we get 10 million gallons of "Pool Algaecide?"

         ;D Mmmm, nice warm pea-green lakes!!!!  ;D

Just kidding!  I need another trip to Crosby or Superior real soon!
