I agree, Tainter is where the problems start for the majority–then comes over the Cedar Falls dam green and Menomin worsens substantually.
The lake associations need to step up, well as all the homeowners around Tainter (water and sewer issues, etc.). I understand the whole watershed is at issue, but clean up the inside of your own cup first-
On a side note, the entire watershed is naturally rich in phosphorus–creating a phosphorus free zone in the watershed would be a global start. Otherwise, the DNR-lake associations could establish filtration stations on the Red Cedar and Hay rivers at the top of tainter and let the people further north clean up their own closets since everyone is turning a blind eye to this menacing and ever increasing problem.
I would never buy a house on Tainter or Menomin unless I suddenly lost my sense of smell.
