There are seven lakes <br />which lie entirely or partially within the City limits of Arden Hills: Lake <br />Johanna, Lake losephine, Little Lake lohanna, Valentine Lake, Round Lake, <br />Karth Lake and Sunfish Lake. RCWD has prioritized lakes within the district <br />on the basis of trophic state indices, recreational facilities and lake capability, <br />Tier I lakes consistently support swimming. Tier 2 lakes are capable of <br />supporting swimming or have significant public uses. Tier 3 waterbodies <br />include all DNR protected lakes, wetlands, and watercourses not included in <br />Tiers I and 2, Tier 4 includes any remaining wetlands, stormwater basins, and <br />conveyance systems. The following table lists the tier identification of the <br />lakes within the City of Arden Hills, according to the Rice Creek Watershed <br />District Water Resource Management Plan. <br /> <br />Table 3 <br />Lake Tier Classification <br /> <br />Lake Tier <br />Johanna 2 <br />Josephine 2 <br />Karth 3 <br />Little Johanna 3 <br />Round 3 <br />Sunfish 3 <br />Valentine 3 <br /> <br />The RCWD Plan does not lists any Tier 1 water bodies in Arden Hills, <br />However, additional water quality data collection and analysis by the <br />Minnesota Pollution Control Agency would indicate that Josephine Lake <br />would be considered a Tier I lake (Section 3, Water Quality Analyses). <br /> <br />The Department of Natural Resources (DNR) Protected Waters which lie <br />within the City limits can be seen in Figure 5. The DNR Protected Water <br />comprise watercourses such as Rice Creek, lakes and wetlands greater than <br />2.5 acres. The DNR has jurisdiction over these protected water bodies at and <br />below the Ordinary High Water (OHW) level The OHW is defIned as the <br />elevation delineating the highest water level which has been maintained for <br />sufficiently long periods of time to leave evidence upon the landscape. <br /> <br />Figure 6 shows the wetlands within the City of Arden Hills that are included <br />in the National Wetlands Inventory (NWl) prepared by the U.S. Fish and <br />Wildlife Service (1991), Areas shown on the DNR and NWl maps indicate the <br />presence of wetlands, but show only the general location of wetlands.
