A resident who lives on Lake Winnebago says while he is upset at the environmental damage caused by a large manure spill at an area dairy farm…he’s more upset that downstream property owners weren’t notified. Paul Osterholm lives on the lake near Pipe Creek. WFDL news broke the story about the spill. "Thanks to Sunny 97.7 I read about it on your website," Osterholm said. Osterholm says he is upset that property owners weren't officially notified by the DNR or county officials. Osterholm says he’s also concerned about the environmental damage and potential threat to human health.
