I ~ I I I I I I I Subwatershed 14a: Lake Josephine Policies: A.3, B.l, B.2, B.3, B.4, B.5, C.1, C.2, C.3, C.4, C.5, E.l, E.2, E.3, E.5, and F This subwatershed totals approximately 1.31 sq mi. The area tributary to the lake was largely developed prior to formation of the District. Cooperative projects performed with the City of Roseville as part of the Long Lake Chain of Lakes Grant enabled a large storm sewer to be diverted from the lake into a wetland treatment area. This improvement has increased the water quality of Lake Josephine and allowed for increased use of the Ramsey County park facilities at the lake. Subwatershed 14b: Lake Johanna Policies: ~~~~~~~~~~~~~~~~F . I I I I I I This subwatershed totals approximately 4.25 sq mi. Numerous projects have been done in the area tributary to Lake Johanna as part of the Long Lake Chain of Lakes Grant. Most notably, Ramsey County Ditch 4 which drains the industrial and retail areas of Roseville has been stabilized to prevent erosion of the channel and deposition of sediment within Johanna. Additionally, the District constructed a new fishing pierllake outlet which greatly moderates the once widely fluctuating lake levels. Shoreline erosion had been a large problem around the basin. Water quality of the lake is monitored annually by the Ramsey County Department of Public Works. Little additional development is expected in this subwatershed and District policies will be to promote retrofitting of stormwater quality measures where feasible. Subwatershed 14c: Round Lake Policies: ~~~~~~~~~~~~~~~~F ~ I The Round Lake subwatershed extends over 0.83 sq mi. Round Lake is managed by the U.S. Fish and Wildlife Service and has an adjustable outlet capable of providing large amounts of storage. This subwatershed had a large amount of undeveloped land riparian to the lake. Preliminary planning efforts indicate it will be commercial/industrial development area 4-23 10/97
