Approval letter for Red Cedar Lakes APM plan.
The Red Cedar Lakes are located in northwestern Barron County and southeastern Washburn County, northwest Wisconsin in the headwaters region of the Red Cedar River. The Red Cedar Lakes consist of three main stem lakes (Balsam, Red Cedar, and Hemlock) on the Red Cedar River, and Mud Lake, a small spring-fed lake flowing into Balsam Lake. The lakes cover more than 2,600 acres and have nearly 39 miles of shoreline. Bass Lake is a small (19-acre) seepage lake adjacent to the northeast shore of Red Cedar Lake. Bass Lake is listed as being 39-feet deep with an average depth of 13-feet. It primarily consists of a warm water fishery with largemouth bass, northern pike, and panfish.
These surveys were designed to map the extent of curlyleaf pondweed beds and provide detailed, statistical assessments of the aquatic plant communities in Red Cedar Lake, Hemlock Lake, Balsam Lake, and Mud Lake (collectively referred to as the “Red Cedar Lakes” hereafter). The information gained from these assessments provides a baseline for evaluating any changes in the plant community over the coming years, and will help to guide responsible vegetation management planning.
This report discusses aquatic plant management activities completed by the Red Cedar Lakes Association (RCLA) and Lake Education and Planning Services (LEAPS) during the 2018 season associated with the AIS Education, Prevention, and Planning (AEPP) project awarded in early 2018. This project covers waters in four different lakes: Balsam, Mud, Red Cedar, and Hemlock.
As a part of the 2018-19 AEPP grant that was submitted a plan for a Rhodamine Dye Study was developed by LEAPS. Calculations were completed that determined that 6.93 lbs of liquid Rhodamine dye would be needed to mimic a comparable chemical treatment application on a 7.6 acre bed of CLP identified in the north end of Balsam Lake in the spring of 2018 (Figure 6, Table 5).

We conducted a late-spring delineation survey to locate and map areas of curlyleaf pondweed (CLP) throughout the Red Cedar Chain of Lakes around the time of peak CLP abundance. Results from this survey will help to evaluate the effectiveness of past CLP control strategies and guide management decisions over the coming years.
