Effects of Land Use on the Biological Integrity of Streams

Watershed ConceptThere is an intimate relationship
between the land and water resources. How we manage land within a watershed strongly influences the quality of its aquatic resources.
“The streams of the Midwest have undoubtedly changed much in character since the country has become so thickly settled. I have been informed that many streams, formerly deep and narrow, and abounding in pickerel, bass and catfishes, have grown wide and shallow, while the water in them varies greatly in different seasons, and they are inhabited by bullheads, suckers and a few minnows.”
Seth Meek, 1892
