Preparation of detailed stormwater management plans to determine the best
practices to be installed in the urban areas. These plans address water
quantity and water quality problems in developed and developing urban
areas.
Current Plan Recommendations
It is recommended that construction site erosion control, onsite sewerage system
management, and streambank erosion control, in addition to land management prac-
tices that would provide at least a 25 percent reduction in nonpoint source
loadings be carried out throughout the Menomonee River watershed. It is further
recommended that rural land management measures needed to achieve the levels of
control set forth in the Menomonee River priority watershed study for sediment
control from rural areas be carried out. It is also recommended that the urban
land management practices set forth in the Menomonee River priority watershed
plan be utilized as the initial basis for stormwater management planning and
project eligibility under the State priority watershed program. These levels of
reduction in the urban areas are recommended to be refined based upon subsequent
detailed stormwater management planning, and based upon additional monitoring and
quantitative analyses which are recommended to be conducted during the plan
implementation period.   These data and consideration of estimated costs and
available funds for the urban practices are recommended to be evaluated to refine
the recommended final level of control. Such refinement would include further
consideration of toxics reduction requirements.
The types of practices recommended to be considered for these various levels of
nonpoint source control are summarized in Appendix A.
WATER QUALITY MONITORING PLAN ELEMENT
Existing Conditions and Status of Implementation
While substantial progress has been made in the regional water quality management
plan elements described in the previous sections, the most direct measure of the
impact of plan implementation on water quality conditions can only be achieved
by a well-planned areawide water quality and biological condition monitoring
program. As of 1993, long-term monitoring has been carried out in the Menomonee
River watershed on a sustained basis by the Milwaukee Metropolitan Sewerage
District for eight stations located on the Menomonee River main stem. Data from
five of these stations were used to document current long-term water quality
conditions in the watershed, as shown on Map VII-5. Short-term monitoring has
also been conducted at one site by the Wisconsin Department of Natural Resources
and at one site by the U.S. Geological Survey during the period 1988 through
1993, as described later in this chapter.
Current Plan Recommendations
Continued water quality and biological conditions monitoring will be needed in
the watershed to document current conditions and to demonstrate water quality
condition changes over time. It is recommended that water quality data collec-
tion be continued by the Milwaukee Metropolitan Sewerage District for all current

stations on the Menomonee River on a continuing long-term basis. In addition,
it is recommended an intensive water quality and biological condition monitoring
program be conducted over a one-year period at five selected additional stations,
with one station each located on Little Menomonee River, Little Menomonee Creek,
Butler Ditch, Underwood Creek, and Honey Creek.   This monitoring program would
