Aquatic Invasive Species
Invasives threaten the survival of native plants and animals, interfere with ecosystem functions, and hybridize with native species resulting in negative genetic impacts. They impede industry, threaten agriculture, endanger human health, and are becoming increasingly difficult to control.
Negligence & Indifference
Long-neglected and abandoned industrial waterfronts can become economic and aesthetic assets to urban centers. Besides, cities are where people live and urban people ought to have access to clean and beautiful rivers.
Polluted runoff – largely from farms, but also from streets, construction sites and badly managed shorelines – is the by far the biggest water quality threat to rivers.
Most of Wisconsin's rivers, lakes and wetlands simply would not exist without an ample groundwater supply. It has long been assumed that our groundwater supplies are inexhaustible, but in some parts of the state, water is being pumped out of the ground at a far greater rate than it can be replenished.
