Wisconsin takes aim at algae - public comment open

Algae stinks.  It clogs up waterways and secretes toxins that are dangerous to humans and our pets.  It’s also a vital part of ecosystems, a necessary base of the food chain.   When nutrient pollution, particularly phosphorus, increases in a water body, excessive algae growth occurs, which results in stinky, dangerous problems. 
 
Algae blooms form dense mats on lakes, rivers and streams, affecting drinking water sources and water recreation.  An 2014 algae bloom in Toledo, Ohio, (shown above) shut down their water supply, leaving the city of more than 400,000 people without water for several days.  Circle of Blue, a website devoted to water issues, provides background information on toxic algae blooms.  We wrote about that in this blog post in January 2017.

Rivers and streams in Wisconsin are affected, too.  At the LWV UMRR Annual Meeting in May, 2017, Kim Wright from Midwest Environmental Advocates talked about excessive algae that chokes the Red Cedar River in Menomonie –read about what she said and see the video of Kim’s presentation here.
 
Thanks to the 2007 and 2016  “Pontoons and Politics” efforts of the Petenwell and Castle Rock Stewards  an advocacy group in central Wisconsin, the Wisconsin Legislature appropriated funds for the Department of Natural Resources to develop a plan to address nutrient pollution, and the resulting algae blooms, on the river.   This article from the Milwaukee Journal Sentinel provides more information on this work, as well as a video on the dangers of blue green algae.
 
This plan is now open for public comment.  It calls for a significant reduction of phosphorus to the Wisconsin River, to be achieved over time.  The DNR website for this project provides copies of the plan and information on how to comment.  This work is mandated by Clean Water Act provisions requiring states to list water bodies whose use is impaired by pollution, detail its sources and suggest limits on future pollution.
