DNR 1 Waters IS AN INDIVIDUAL PERMIT REQUIRED? For most projects constructed below the ordinary high-water level* (OHWL) of public waters, an individual Public Waters Work Permit is required by the Minnesota Department of Natural Resources (DNR).

Please note that local units of government and other agencies may require a permit for this project. *For lakes and wetlands, the OHWL is the highest elevation that has been maintained as to leave evidence on the landscape. It is commonly that point where the natural vegetation changes froin predomi- nantly aquatic to predonunantly terrestrial. For watercowses. the OHWL is the top of the bank of the channel. For reservoirs and flowages, the OHWL is the operating elevation of the normal summer pool. Will a sand beach work on my shoreline? One goal of DNR Waters is to Iimit unnecessary and potentially damag- ing alterations to shorelines. Specifically, use of beach sand and other types of fill is limited in order to prevent damage to fish spawning areas, aquatic habitat, and water quality of Minnesota's lakes. Although natural sand beaches can be found on many Minnesota lakeshores, landowners often attempt to create them on shores where they do not naturally occur (i.e., a muddy -bottom lake). if you are considering adding beach sand, you should know a few important things before investing your money. • Wave action, no matter how minitnal, will erode your beach and the sand will migrate down shore. • You are only allowed to install sand or gravel twice in the same location; after that, an individual permit is needed. • The beach sand that erodes into the lake may coat aquatic plant beds and fish spawning grounds, degrading fish and wildlife habitat and damaging the water quality of your lake. • Vegetation will constantly emerge through the sand, and additional plant control will be needed on the beach. If you plan to weed by hand or apply herbicide, an aquatic plant management permit may be required from the DNR Division of Fisheries. • Sand blankets may not be placed over emergent vegetation such as bulrush or cattails unless you obtain a permit from the Division of Fisheries. • if the lake bottom is soft, the sand will only sink into the muck and disappear. Keep in mind that you are not allowed to install any plant barrier or liner (e.g., filter fabric or plastic) underneath your beach sand. If owning lakeshore property with a sandy beach is a high priority for you, look for lakeshore property where sandy beaches occur naturally before you make that important purchase.
