MENOMONEE RIVER WATERSHED REGIONAL WATER QUALITY
MANAGEMENT PLAN UPDATE AND STATUS REPORT
INTRODUCTION
This chapter presents a description of the recommendations contained in the
initial regional water quality management plan and amendments thereto, and
progress made toward plan implementation from 1975--the base year of the initial
plan--through 1990--the base year of the plant update. In addition, this chapter
presents information on water quality and biological conditions in the surface
water system of the Menomonee River watershed through 1993, where available.
Finally, this chapter presents a description of any substantive water quality
management issues that remain to be addressed in the Menomonee River watershed
as part of the continuing water quality planning process.     The status of the
initial plan and the current plan recommendations are presented in separate
sections for the land use plan element, the point source pollution abatement plan
element, and the water quality monitoring plan elements. In addition, a brief
separate section on lake management is included which is limited for the
Menomonee River watershed as there are no major lakes in the watershed. Desig-
nated management agency responsibilities for plan implementation are presented
in Chapter XVII on a regional basis.
The Menomonee River watershed is located in the east central portion of the
Region and covers an area of approximately 135 square miles. The Menomonee River
originates in southeastern Washington County, and flows approximately 28 miles
through the northeastern corner of Waukesha County and through western and
central Milwaukee County to its confluence with the Milwaukee River. Rivers and
streams in the watershed are part of the Lake Michigan drainage system as the
watershed lies east of the subcontinental divide. The boundaries of the basin,
together with the locations of the main channels of the Menomonee River watershed
and its principal tributaries, are shown on Map VII-1.      The Menomonee River
watershed contains no lakes with a surface area of 50 acres or more.
LAND USE PLAN ELEMENT
The land use plan element of the initial plan, the status of the initial plan
recommendation, as well as the new year 2010 plan, were described in Chapter III
of this report on a regional basis. This section, more specifically, describes
the changes in land use which have occurred within the Menomonee River watershed
since 1975, the base year of the initial regional water quality management plan,
as well as the planned changes in land use in the watershed to the year 2010.
The data are presented for the watershed in order to permit consideration of the
relationship of the changes in land use to the other plan elements and to water
quality conditions within the watershed. The conversion of land from rural to
urban land uses has the potential to impact on water quality as a result of
increased point and nonpoint source loadings to surface waters. The amount of
wastewater generated by industrial and municipal point sources of pollution
