CMP Part 3A. Environmental Protection Plan Lydiard Lake is the most rural of Orono's lakes, being surrounded by heavily wooded rolling hills. Dickey's Lake has become surrounded by low density residential development over the past 30 years. Lake Classen is surrounded by orchards, woods and open fields with a handful of homes overlooking its' waters. The Orono School District maintains a nature study area and waterfowl ponds on Classen's east shore. Mooney Lake's shore is relatively undeveloped in Orono and Medina, but the lake's watershed has received growing pressures from urbanization in Plymouth, including usage conflicts, elevation concerns due to lack of a natural outlet, and urban storm water pollution inflow. Long Lake is the second largest and 2nd most actively used lake in Orono. The east and west shores have been developed at rural residential densities. The north shore has mixed rural residential areas and one denser housing cluster dating from the 1930's. The south shore is bordered by the City of Long Lake and is urbanized to the same degree as much of Lake Minnetonka. Long Lake has experienced storm water problems as well as increased usage pressures. In recent years, the expansion of Carp and other fish have suspended solids, degrading water quality. The Cities of Medina, Long Lake, and Orono have agreed to study the issue. Orono also has identified a number of protected tributary streams which are subject to Shoreland regulations. These are shown in the following table: Table 3A-3: Protected Tributary Streams Tributary Name From: To: Impaire d Water Section Township Range Section Township Range Long Lake Creek 35 (Basin 160-P) 118 23 10(Basin 141-P) 117 23 N "Wolsfeld" Creek 27 (City limit) 118 23 26(Basin 160-P) 118 23 Y Tributary to Wolsfeld Creek from Holy Name Lake 26 (City limit) 118 23 27 118 23 Dickeys Lake Creek 27 (Basin 161-P) 118 23 34 (Basin 160-P) 118 23 N Stubbs Bay Creek (aka Classen Creek 32 (Basin 162-P) 118 23 5 (Basin 133-P) 117 23 N Painter's Creek 30 (Basin 154-P) 118 23 31 (City limit) 118 23 Y Source: City Records, MPCA The second most significant and most universal natural amenity in Orono is its many wetlands and marshlands comprising Lake Minnetonka's upland drainage system. Orono's nearly 1600 acres of marshland and wetlands comprise fully one-sixth of the City's land area. Map 3A-2 indicates how the marshland and drainageways are scattered throughout the City.
