Estabrook Dam

Project Description

On July 28, 2009, the department sent Milwaukee County, prior owner of Estabrook Dam, an Administrative Order to Repair or Abandon the Estabrook Dam. The Order was required to protect public health and safety and to ensure the dam meets acceptable design standards. Milwaukee County initially decided to repair, operate, and maintain Estabrook Dam. The department prepared an environmental impact statement (EIS) to analyze the operation of the dam.

On December 16, 2016, Milwaukee County applied to transfer ownership of the Estabrook Dam to the Milwaukee Metropolitan Sewerage District (MMSD).The department approved the transfer request on January 19, 2017. On May 1, 2017, the department deemed MMSD’s application to abandon the Estabrook Dam complete to the point that the department could start reviewing the application.

Environmental review process

Both the transfer of dam ownership and abandonment of the dam are Minor Actions under Chapter NR 150, Wisconsin Administrative Code. Given the history of this project, the department will be reviewing the proposed abandonment as an Integrated Analysis Action. This incorporates existing project documentation as well as new data and studies required for regulatory permit reviews into a complete analysis of the project impacts. The following documents are publically available here:

Abandonment permit

The abandonment permit application from MMSD is publicly available at the Water Permitting Site.

The permit application has been reviewed and the approval letter has been issued.
