Researchers in Ashland are seeing higher amounts of phosphorus in waters near Lake Superior. They say levels exceed state water quality standards in a creek that’s downstream from where a large hog farm may be built.

Randy Lehr with the Center for Freshwater Innovation at Northland College said they’ve been sampling water quality at three sites in South Fish Creek, near the site where Iowa-based Reicks View Farms plans to build 26,000-hog operation in Bayfield County.
