Restoration Plan for Oak Creek Watershed

The Commission staff is preparing a restoration plan for the 28-square mile Oak Creek watershed, which is located entirely within Milwaukee County and includes portions of the Cities of Cudahy, Franklin, Greenfield, Milwaukee, Oak Creek, and South Milwaukee (see Map 1). The plan is being prepared within the context of the 2007 SEWRPC regional water quality management plan update for the greater Milwaukee watersheds. The watershed restoration plan will provide a guide for addressing the water quality impairments that have been identified in the watershed, and it will include specific, targeted recommendations to address a set of focus issues related to conditions within the watershed. 

The Oak Creek plan is designed to maximize funding opportunities for plan implementation by addressing the nine elements of a watershed-based plan as identified by the U.S. Environmental Protection Agency (USEPA).

The following four major focus areas are being addressed by the watershed restoration plan:

  • Water quality,
  • Recreational access and use,
  • Habitat conditions, and
  • Targeted stormwater drainage and flooding issues.

In addition, the status of the Mill Pond and the associated dam located on Milwaukee County parkland within the City of South Milwaukee are being addressed considering their relationship to multiple focus issues.

In 2020 SEWRPC staff completed draft Chapter 4—Inventory Findings and draft Chapter 5—Watershed Goals and Management Objectives. In 2021 SEWRPC staff will complete draft Chapter 6—Recommendations which is the final chapter for the Plan.
