Lake Erie Phosphorus Pollution is Ideal for Invasive White Perch
The phosphorus-fueled harmful algal blooms around western Lake Erie are finally going away as water temperatures have fallen below the 60-degree mark in recent days. The phosphorus pollution causing the blooms, however, has also provoked changes in the fish populations of Lake Erie.

White perch, an invasive species thriving in the brackish waters of the East Coast, entered Lake Erie through the Welland Canal a few decades ago.

Their numbers have been on the rise in recent years. The white perch prosper in nutrient-rich water, unlike walleye, yellow perch and smallmouth bass. The phosphorus pollution that prompts the HABs and the noxious green slime in late summer and early fall has turned Lake Erie's Western Basin into eutrophic, or nutrient-rich waters more suited for white perch than the native favorites of fishermen.

DNR’s Impaired Lake List - The federal Clean Water Act (CWA) requires that states adopt water quality standards to protect waters from pollution. These standards set the water quality goals for a lake, river, or stream by stating the maximum amount of a pollutant that can be found in the water while still allowing it to be used for fishing, swimming, and allowing aquatic organisms and wildlife to thrive
