Kalamazoo River Stream Bank Erosion Site Survey Extending from Augusta to Otsego, Michigan
Andrus, David R.
The Kalamazoo River, like all rivers, experiences an influx of various types of pollution from the elevated land around it, known as a watershed. This pollution is collectively referred to as nonpoint source pollution. One major cause of nonpoint source pollution in a river's watershed comes from the erosion of sediment from the river bank directly into the river. Not only does erosion carry the problem of depositing sand and silt into the river with ecological consequences such as water temperature flux and flow redirection, but, in many areas of the Kalamazoo River in particular, the sediment carries with it polychlorobiphenyls (PCB's). PCB's are known to be extremely detrimental to the vitality of the surrounding ecological niches. This erosion site survey the Kalamazoo River was overseen by the Nonpoint Source Pollution Advisory Committee of Kalamazoo County, a small coalition of local businesses and environmental organizations. The river survey was conducted via canoe, using topographic maps and aerial photographs of Kalamazoo County and Allegan County. It resulted in the identification of 19 sites, 3 being of minor severity, 13 of moderate severity, and 3 severe sites. This report outlines the methodology underlying the quantitative and qualitative measurements taken to categorize the severity of each of these sites, as well as describing each site, individually. This study is designed as one of the primary initiatives towards treatment of the nonpoint source pollution problem facing the Kalamazoo area.
