The Wisconsin Department of Natural Resources has signed a four-year agreement with a unit of Xcel Energy to maintain predictable water levels and enhanced downstream flow, particularly during spring, on the Manitowish Chain of Lakes through the operations of the Rest Lake dam.
The agreement, with Xcel’s Chippewa and Flambeau Improvement Co., was developed to address concerns of property owners above the dam while providing for more water downstream to improve habitat for spawning fish and allow for more gradual change in downstream water levels. The agreement calls for the dam owner to install a temperature meter just below the dam to maximize river flows during prime spawning periods.
The Memorandum Of Understanding (MOU) clarifies the operating order for the dam and allows an earlier start in spring to manage water flows that, in the past, were quickly discharged through the system. The management protocols contained in the MOU will be evaluated regarding the impacts both upstream and downstream of the dam to help determine its future operation.
Chippewa and Flambeau Improvement Co. has agreed to install a downstream gauge and provide monitoring and reporting of both chain water levels as well as downstream flows. This information will be posted on a website that will be determined in the weeks ahead.
