Zach Christian-Rotramel

The purpose of this study was to examine the relationship between land cover
change and water quality (transparency), in Michigan inland lakes between the years 1998 and 2005. Water quality data were obtained from the Michigan Clean Water Corps (MiCorps) and processed in Microsoft Excel to display a percent change between the two study years. The lakes studied showed a change ranging between a 21.62% increase to a -26.00% decrease in transparency. Aerial images were obtained from Michigan's DOQQ (Digital Ortho Quarter Quad) image archive, land cover types were digitized in ArcGIS for each lake studied. Each image was classified into six use/cover categories including agriculture, barren land, forest, grass, urban development, and water. A regression analysis was used to determine change in land cover types.
