analyses to determine the current degree of achievement of the recommended water
use objective for the stream reaches concerned. In some cases, this evaluation
may indicate that the water use objective should be changed. For example, in the
Root River watershed, the recommended point source pollution abatement measures
have now been largely carried out, including the abandonment of seven public and
seven private sewage treatment plants and the upgrading of the Village of Union
Grove sewage treatment plant. Given that the nonpoint source priority watershed
project implementation period has been completed and that the surface waters
still do not fully meet the standards for the recommended water use objective,the
achievability of the objective should be reevaluated along with the need for
further nonpoint source controls.
For the Upper Fox River, Menomonee River, and Milwaukee River watersheds, the
levels of control developed for the urban areas in the priority watershed plan
are significantly higher than those developed in the initial regional water
quality management plan. In this regard, it should be noted that the priority
watershed plans included consideration of water quality implications of metals
toxicity in stormwater. Such metal toxicity was not specifically considered in
the development of the initial regional plan recommendations since metals
toxicity standards were not available at the time of its preparation. However,
levels of urban control developed under the priority watershed plans for these
three areas are costly and full implementation will be difficult to achieve.
Thus, it is recommended that the level of control for urban areas 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 refine-
ment would include further consideration of toxics reduction requirements.
It is further recommended that local agencies charged with responsibility for
nonpoint source pollution control prepare refined and detailed local-level
nonpoint source pollution control plans to identify the nonpoint source pollution
control practices that should be applied to specific lands in the most cost-
effective manner. In this regard, those areas of the Region not yet included
under the Wisconsin Nonpoint Source Priority Watershed Pollution Abatement
Program should be enrolled in the program in order to make State cost-sharing
funds and related programs available for nonpoint source pollution control
measures. In addition, detailed stormwater management plans in urban areas and
farmland management plans in rural areas should be conducted to determine the
practices to be installed in the most cost-effective manner.         The current
priority ranking of watersheds for inclusion in that program is documented in a
memorandum14 prepared by the Regional Planning Commission using DNR procedures.
That ranking is summarized on Map XVIII-10 and Table XVIII-9, and includes the
Bark River, Middle Fox River, Lower Fox River, Oak Creek, Pike River, Pike Creek,
Sauk Creek-Sucker Creek, East Branch Rock River, and Rubicon River in the high
category, indicating that inclusion in the program will be possible in the future
when the existing planning projects are completed, or additional funds and staff
become available with the Department of Natural Resources. The Commission is
