Survey Description

The Little Menomonee River originates in southern Ozaukee County near Freistadt Road and flows in a mostly southerly direction for a distance of approximately 10-miles to its confluence with the Menomonee River near Highway 100 and Hampton Avenue (Timmerman Field area). The Little Menomonee subwatershed encompasses approximately 21.8-square-miles, or nearly 16% of the Menomonee River watershed and includes portions of the communities of Mequon, Germantown, and Milwaukee. It is entirely confined within the borders of Ozaukee and Milwaukee Counties. The majority of the river is contained within natural stream banks. Previous studies have not identified significant historical flooding issues associated with the Little Menomonee River in Milwaukee County; outside of the county, some flooding and/or road overtopping events have been reported. The Little Menomonee River was added to the MMSD sampling program in 2007 and includes two sites (see Table 3). The two sampling sites are designated with an “ML” and a site number. Surveys are scheduled for sampling approximately twice per month from March – December. The monitoring plan is to collect data from this subwatershed in order to assess potential water quality impacts stemming from the Little Menomonee.
