City of Lino Lakes SWMP | February 8, 2013 Draft | 88 <br />Metals <br />Metals dissolved in water. Typical metals <br />included in monitoring programs are cadmium, <br />chromium, copper, lead, nickel, and zinc . <br /> <br />Nonpoint source pollution <br />Pollution, such as nutrients and sediment, that <br />are not from one distinct origin. For example, <br />soil can run off of land throughout the <br />watershed, it does not come from just one point. <br /> <br />Nutrient <br />Element essential for plant or animal growth. <br />Major nutrients include nitrogen, phosphorus, <br />carbon, oxygen, sulfur, and potassium. Within <br />surface water systems, nutrients such as <br />phosphorus and nitrogen can lead to the <br />excessive growth of algae. <br /> <br />Nutrient/Eutrophication B iological Indicators <br />A surface water impairment based on high levels <br />of nutrients that cause eutrophication and <br />changes in the biological community. <br /> <br />Outwash plain <br />A region of relatively flat to undulating <br />topography covered by sediment deposited by <br />the gl acier meltwater. Outwash is usually <br />composed of sand, sand and gravel, or fine sand <br />and silt. <br /> <br />Special Area Management Plan (SAMP) <br />The SAMP provides a watershed -based and <br />conservation -based framework for aquatic <br />resource management, particularly as <br />development and redevelopment occur within <br />the City. The SAMP addresses future water <br />quality, quantity, flow rates and wetland <br />function an d condition in light of forecasted <br />development and potential changes to surface <br />and groundwater characteristics. The Army <br />Corps of Engineers St. Paul District (Corps) uses <br />the SAMP in its Clean Water Act Section 404 <br />permit evaluations within the area addre ssed by <br />the SAMP. <br /> <br />Stormwater/Stormwater runoff <br />The water that flows off a site after a rainstorm. <br /> <br />Subwatershed <br />A smaller geographic section of a larger <br />watershed unit with a drainage area of typically <br />between 2 and 15 square miles and whose <br />boundaries include all the land area draining to a <br />specified point. <br /> <br />Total Maximum Daily Load (TMDL) <br />The maximum quantity of a particular water <br />pollutant that can be discharged into a body of <br />water without violating a water quality standard. <br />TMDL also refers to the p rocess of allocating <br />pollutant loadings among point and nonpoint <br />sources. <br /> <br />Watershed <br />The geographic region within which water <br />drains into a particular river, stream, or body of <br />water. <br /> <br />Water Quality <br />Water quality is a term used to describe the <br />chemical, physical, and biological characteristics <br />of water, usually in respect to its suitability for a <br />particular use. In the case of surface waters, uses <br />are typically swimming and fishing. <br /> <br />Wetland Restoration <br />The re -establishment of a wetland functi ons in a <br />wetland area that had previously been altered <br />due to draining, filling or other means.
