NEW ULM - The Brown County Girl Scouts and the River Rangers raked leaves out of over 100 blocks of City of New Ulm gutters on Saturday to help make the local rivers cleaner.
The event kicked off at Riverside Park with Brown County Wetlands Administrator John Knisky giving a demonstration on how leaves from the trees can create algae in the river. He explained at five pounds of leaves washing into the river from street sewer drains could break down into approximately a pound of phosphorous, which in turn could grow up to a thousand pounds of algae per pound of phosphorous.
The 32 kids in attendance and their accompanying parents performed some water testing on the Minnesota River before moving on to systematically raking up leafs from several city blocks of street gutters to prevent the leaves from washing into the sewers.
