Study indicates Asian carp may already be in Great Lakes by EmanueleB

A new study released in April finds Asian carp may in fact be reaching the Great Lakes.  The Asian carp is an invasive species with an appetite large enough to potentially decimate the food chain ecosystem of the Great Lakes.  There have been many efforts to contain the spread of the fish in the Chicago Area Waterway System to connects to Lake Michigan.  The study now raises new questions about the effectiveness of that system. Current State’s Mark Bashore talks with study co-author Dr. Andrew Mahon, assistant professor of biology at Central Michigan University, and Dr. Tammy Newcomb, senior water policy advisor for the Michigan Department of Natural Resources.

Fate of Great Lakes water and energy are linked

By |

The dependent relationship between energy and water is important, but in a water-rich state like Michigan, it’s easy to overlook. Skip Pruss discusses the water-energy nexus  and its potential impact on the future of the Great Lakes. Pruss is a Principal at 5 Lakes Energy and former Deputy Director of the Michigan Department of Environmental Quality. Current State: Water-energy nexus in the Great Lakes Basin by Great Lakes Echo

Plant wars kick in when dams come out

By |

Dam removal in the Great Lakes region exposes nutrient-rich bottomlands.

That creates prime real estate for invasive plants.

Restoration solutions include poisoning the invaders with pesticides and spreading native plant seeds to revegetate the bottomlands.

Current State: Michigan’s groundwater at risk

By |

The Great Lakes’ record-low water levels are rightly receiving all of the attention now, but evidence is growing that Michigan’s fragile groundwater resources are quietly becoming a concern for the future. Robert Glennon, professor of law and public policy at the University of Arizona and author of “Unquenchable: America’s Water Crisis and What to do About It,” knows Michigan well and shares his insights. Echo has reported on the consequences of drought on Great Lakes groundwater – which can also be seen on this map – and the challenge of measuring its effects. The need for better groundwater conservation continues to be a widely overlooked issue facing the Basin.

A program for fixing sewers is at risk because of the federal budget crisis. It comes as climate change is expected to bring more heavy rains that cause sewers to overflow. Advocates say the program helps struggling cities, the environment, the economy.
