There are seven lakes <br />which lie entirely or partially within the City limits of Arden Hills: Lake <br />Johanna, Lake Josephine, Little Johanna Lake, 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 1 lakes consistently supporting swimming or have signifieant public uses, <br />Tier 3 waterbodies include all DNR protected lakes, wetlands, and <br />watercourses not included in Tiers 1 and 2. Tier 4 includes any remaining <br />wetlands, stormwater basins, and conveyance systems. The following table <br />lists the tier identification of the lakes within the City of Arden Hills. <br /> <br />Table 2 <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 I 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 Riee 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 oftime 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 (NWI) prepared by the U.S, Fish and <br />Wildlife Service (1991), Areas shown on the DNR and NWI maps indicate the <br />presence of wetlands, but show only the general location of wetlands.
