anticipate hosting fishingopportunities on Round Lake similar to these areas and propose to <br />partnerwith MNDNR to bring FIN program activities to Round Lake.Fishing in the <br />Neighborhood seeks to increase angling opportunities, public awareness and environmental <br />stewardship within the metro region.Fishing will be allowed from the shore and a designated <br />fishing platform. No boats will be allowed on the lake in order to minimize disturbance to <br />wildlife using other parts of Round Lake. <br />Some improvements to Service infrastructure are central to providing these public uses (Figure 2, <br />Figure 3). We propose a spur trail that would extend from the existing trail on the west side of <br />the Unit to a new fishing platform on the southwest side of Round Lake. Another trail will be <br />placed on Refuge property adjacent to the Round Lake outlet. This trail will start at Old <br />Highway 10 and follow the lake outlet channel to the southern lakeshore. From there the trail <br />willfollow the lakeshore to the west and link up with either the existing trail on the west side of <br />the lake or the City’s park property midway along the southern shore. Prior to the Round Lake <br />Unit being placed in caretaker status in the early 1980s, the City of Arden Hills was actively <br />discussing linking the city park with the Unit. We envision that will finally occur. <br />A new observation platform specifically designed for environmental education and interpretive <br />programming will be constructed on the Service lakeshore either near the outlet channel or <br />adjacent to the city park. This platform would be designed to provide both a good view of the <br />entire lake surface as well as easy access to the wetland habitat along the shore. <br />Similar proposed actions to accomplish Service objectives for the Round Lake Unit were <br />identified in earlier Unit management documents in 1979, 1982, and 1998 (USFWS 1979, 1982, <br />1998). The Service’s planned management actions were modified to manage ecological risk <br />upon discovery of significant contamination of the Round Lake ecosystem in the early 1980s <br />(USFWS 1981). The Service presumes that the current ecological risk posed to the Round Lake <br />ecosystem will be mitigated via the actions of the Superfund remediation project in such a <br />manner that enable this vision to be fulfilled. <br />Resource Management Concepts <br />Water Management. The dominating feature of the Round Lake Unit is Round Lake itself. The <br />lake is about 125 acres at a surface elevation of 890 msl (Table 1). At this elevation, the lake has <br />a maximum depth of nearly 22 feet. Since about the mid-1980s the lake elevation has been <br />managed to try and maintain a level of 891 msl in order to reduce the exposure of wildlife and <br />people to the contaminated sediments. A 1978 survey of the lake showed substrate consisting of <br />20% sand and rocks, 20% muck, and 60% detritus (Joarnt and Kenow, 1978). More recent <br />samplingin 2011showed 6% sand, 1% silt, 43% muck, and 50% peat in the upper 0.5 ft. of the <br />substrate; and showed 10% sand, 2% silt, 22% muck, and 66% peat in the 0.5 ft. to 1.0 ft. layer <br />8/6/2013 6 USFWS RLMP <br />
