Waterbodies TRCA

An area on the landscape that accumulates water, can be natural or artificial. We classify into 6 different classes; lake - have "lake" in their official name (includes Lake Ontario), should be naturally occuring although may have portions of the shoreline which are artificial, may or may not have an outlet, natural pond- generally smaller than a 'lake', often no official name, largely or entirely natural shoreline, includes beaver ponds, may or may not have an outlet, estuary- found exclusively along Lake Ontario shoreline upstream from river mouth to first riffle or approximately 77m ASL but is confined to the 'backwater' areas of coastal marshes, i.e. does not include the main river channel, always has an outlet, SWP- stormwater management pond, only those with water should be delineated (no 'dry' ponds to be included), always have an outlet, artificial- golf course pond, farm pond, reservoir, gravel or quarry pit, man-made on-line pond, may or may not have an outlet, and unknown - includes temporary SWP or any water body in an actively developing area, any other water body that doesn't fit in to the other classes. It can be difficult to distinguish between natural and artificial waterbodies, where the interpreter is unsure the feature can be classed as "unknown".In all cases the boundary of the water body should be placed where the shoreline is seen to be or can be reasonably assumed to be, in cases where the shoreline isn't clear the boundary should be placed at the edge of the open water and should then be coincident with an adjacent Natural Cover polygon.
