WETLANDS In recent years people's attitudes regarding wetlands have b. Plan changed a great deal. Wetlands are no longer thought of as wastelands and producers of disease. The reason for this dramatic change in attitudes is the recognition of the important role wetlands play in our environment. The im- portance of wetlands can be summarized as follows: LAKES a. Inventory 1) Wetlands affect the quality of water by acting as a filter and storing organic materials in the leaves of aquatic plants. Wetland areas are also important as a natural ponding basin. These areas help recharge the water table and reduce peak storm water run -off flows, thereby reducing the flooding potential. 3) Wetlands provide an essential breeding, nesting, and feeding ground for wildlife. 4) Marshes occurring in upland depressional areas can reduce soil erosion by reducing the velocity of the run -off. Type 6. SHRUB SWAMPS: Waterlogged areas along sluggish streams and floodplains, supporting dog- wood, willow, alders and many forms of wildlife. In Ramsey there is an abundance of wetlands, some found along the edges of the streams and rivers, and the others in upland depressional areas. The wetlands are not con- centrated in one area, but rather scattered throughout the community. All wetlands of 1 acre or more have been mapped. (Map 1, Surface Hydrology) The size and location of wetlands determine their value in maintaining water quality, minimizing flood damage, and preserving wildlife habitat. All wetlands identified as part of the proposed storm drainage system should be pre- served. All other wetlands should limit filling to prevent flooding or reduction of the natural nutrient stripping capacity to below the projected nutrient production of the wetland watershed. 4. LAKES Lakes, Minnesota's pride and one of Ramsey's sources of recreation and beauty, become sources of concern when altered by surrounding development. High levels of precipitation can 9
