What Are Shoreland BMPs?Best Management Practices (BMPs) are actions you can take to reduce your impact on the environment. BMPs have been described for agriculture, forest management, and construction. This series of fact sheets describes BMPs you can adopt on your shoreland property to help protect and preserve water quality. In many cases, the best management for shorelands may be retaining the natural characteristics of your property. These BMPs are guidelines that have been established for many areas of shoreland property. As more research is carried out along shorelines to measure the impact of landuse activities on water quality, BMPs may be refined or revised. In the meantime, these fact sheets will assist you in making decisions about your property to minimize impact on Minnesota's valuable water resources. Some BMPs are clearly aimed at residents who already live seasonally or year-round on their shoreland property and who value the resource enough to protect it. /Other fact sheets are designed for those developing new acreage in the future or for short-term visitors to Minnesota waterways. The guidelines are equally appropriate for property near lakes or rivers, and all are relevant for every Minnesotan who shares a commitment to preserve our abundant water resources. Even if you do not live directly on the shoreline, the way you manage your household wastewater and property can have a significant impact on water quality downstream. Pathways that carry contaminants may not always be obvious. Drain tiles, ditches, storm sewers, paved roads, and shallow ground water can all carry pollutants from residential, industrial, and agricultural areas into lakes, rivers, or wetlands. Fertilizers and chemicals applied to lawns or crops can wash down driveways or ditches and end up in surface water. Improper disposal of hazardous household waste or industrial chemicals can add toxics to our lakes. Poor landuse and construction practices result in erosion, increasing the load of sediment in our rivers. These adverse impacts on surface and ground waters not only affect water quality for human use, but also damage wildlife and fish habitat and /Other natural resources. Use of the Fact SheetsThese fact sheets may be distributed to shoreland property owners, lake association members, local elected officials, technical staff, and /Other decision makers. Individual fact sheets may be copied and handed out at meetings or information booths. Fact sheets may be reproduced as pages in newsletters or included with mailings such as utility bills or tax statements. See reverse side for additional guidelines on use. On the inside front cover of the folder is a property management section. Locate the appropriate information for your property and buildings and record it in the folder. Most of the fact sheets outline simple actions to implement on your shoreland property or household to minimize adverse impacts on water quality. For help in getting started on more technical projects, fact sheet #16 Accessing Information to Protect Water Quality gives additional information about the agencies and organizations that can provide assistance. Shoreland Stewardship Scorecard, fact sheet #17, lets you measure your success in protecting water resources.
Helpful Definitionsbeach sand blanket--Sand that is added to form a beach; it should not be added where it would destroy fish or wildlife habitat, wild rice or /Other protected vegetation; size restrictions do apply; contact the DNR Area Hydrologist for specifics. erosion--The process by which soil or rock material is worn down and carried away by wind or water; erosion is increased when vegetation is removed and soil is left exposed. eutrophic--Water very high in nutrients, generally referring to lakes; lakes commonly experience algal blooms and excessive weed growth. filter strip--Vegetated area adjacent to shoreline that helps prevent contaminants from reaching the water; preferably native vegetation. infiltration--Water seeping into the ground through pores in soil, sand, or gravel or through cracks in bedrock; infiltration can help minimize erosion. ordinary high water level (OHWL)--Highest water level that a lake has maintained for enough time to leave evidence on the landscape; commonly where natural vegetation changes from aquatic to upland species; for streams, the OHWL is generally the top of the bank of the channel. riparian zone--Land area adjacent to a stream or lakeshore that may experience periodic flooding. runoff--Water flowing over the surface of land or soil; runoff can cause erosion and is increased when surfaces are paved or covered with roofs, patios, or decks. setback--The required distance between the shoreline and property development; different distances apply for dwellings, septic systems, outbuildings, and wells; required setbacks vary for different water bodies; county and municipal ordinances may vary. shore impact zone--Land area adjacent to a shoreline in which certain regulations apply; some activities are prohibited. shoreland regulations--DNR regulations determining the type and extent of development allowed near shorelines; counties or municipalities may adopt more restrictive ordinances. topography--Shape or contour of the land; topography and slope influence how property should be developed; construction or /Other activity on steep slopes increases runoff and erosion. water bar--A small, raised ridge on the road surface used to deflect water flow into a ditch; designed to reduce erosion by minimizing flow down the road. watershed--The drainage basin or area in which surface water drains toward a lake or stream; ground water flow may or may not parallel surface topography.
