Keeping Asian Carp out of the Great Lakes
A study found that in order for carp eggs to hatch, giant river systems with at least 62-mile stretches of moving water within a limited temperature range are required. However, a more recent study by the U.S. Geological Survey concluded that the eggs could hatch if the right conditions were sustained in a stream for as little as 16 miles. That suggests that other tributaries will be identified in which successful carp spawning is possible; such as the Milwaukee River, St. Joseph, Maumee and Sandusky Rivers.

A thriving population of carp might pilfer enough of the tiny plants and animals on which young and smaller fish feed to drive down the survival rates of such prized species as salmon, walleye and yellow perch, which form the base of a multibillion-dollar sport fishing industry. Walleye and yellow perch in Lake Erie already are struggling and likely won’t be helped by more competition for food.

Stormwater Runoff Will be Directed Toward Irrigation Ponds - Although Minnesota is the land of 10,000 lakes that doesn’t mean water is an inexhaustible resource. Woodbury Minnesota has an innovative idea in order to use stormwater runoff from a 1.75-mile stretch of County Road 19 to use as irrigation for nearby Eagle Valley and Prestwick golf course.
