Officials at the University of Minnesota Duluth have found a solution to campus soil erosion. Permeable pavement allows for natural water filtration but prevents erosion at common footpath shortcuts.

Facing an inhospitable habitat, fish have to move or die, says Bryan Pijanowski of Purdue University. “Some of the fish live in aquatic systems that are completely compartmentalized — they’re dammed off,” he says. “So they can’t move.”

The Great Lakes region receives 4 percent of its energy needs from biomass resources, according to a regional biomass energy program. But some estimates put the potential for biomass at 15 to 20 percent.

A biological balancing act between the premier Great Lakes sportfish and its prey could be at a tipping point in Lake Ontario.

Chinook salmon are the foundation of the Lake Ontario recreational fishery.

Resource officials in northern Great Lakes states are warning litterbug ice anglers to clean up their act.

Enforcement officers finding trash near favorite ice fishing spots are not pleased.

Last February, Deur was asked by the Healing Our Waters Coalition, a group working to restore the Great Lakes, to lobby in Washington, D.C. on Great Lakes Day. He was the only surfer among 100 business leaders, lobbyists and activists discussing the restoration and protection of the lakes on Capitol Hill.

Amid concern and confusion over Asian carp possibly finding their way into the Great Lakes, many experts involved in the controversy agree that other invasive species are likely to show up too.

Non-native wildlife are common in the Great Lakes, with more than 140 species living in them. Sea lampreys were first found in Lake Ontario in the 1830s.
