The County is located in the southeastern corner of Wisconsin, on 45 km of western Lake Michigan shoreline (Figure 1). Elevation ranges from 177 to 294 m above sea level, and except for a few isolated spots where dolomite bedrock is exposed at the surface, the entire County is covered with glacial deposits ranging from large boulders to fine-grained clays. Soils are generally classified as: "silty clay loam till", "loam to clay loam", and "organic mucky peat"(Parker, et al. 1970). There is east-west variation in temperature and precipitation in Ozaukee County due to the presence of Lake Michigan, with average monthly temperatures ranging from -7.1 to 20.7 o C and precipitation and snowfall averaging 77 and 93 cm per year respectively (NRCS WETS Station 1999). Surface drainage is provided by approximately 250 km of rivers, streams, and creeks, all of which eventually flow into Lake Michigan. These streams are geologically young (established after the last glaciation), and as a result of inefficient drainage, many marshes, bogs, and small lakes were formed in the County landscape. Current land use is variable and includes: residential, commercial, industrial, agricultural, wetlands, woodlands, and unused rural/open lands. The amount of land in Ozaukee County devoted to urban land uses has increased by 170% since 1963 (SEWRPC 1997).
