Looking over my area, I am proud to say that there a ridiculous number of fresh water sources. Canada is renowned as possessing one of the largest supplies of natural fresh water in the world. My province does not buck that reputation - there are a tremendous number of bodies of water, both big and small, that serve to provide all of the water needs of the population. That's the good part.
The bad part is that most of these water sources were added via the CanVec data available from the Department of Natural Resources. This is good topographical data, but it is not completely accurate. In one case, a fresh water source is itemized in that data with no corresponding information in the satellite data available through Bing. Another has a water source that is significantly different in shape from the aerial data. I am hesitant to delete the CanVec markings as they are based on professional surveys of te region. Still, the lack of any 1 to 1 consideration in it gives me pause. For egregious examples, my instinct is to plan a visit to the site - I can probably settle the matter fairly swiftly that way.
The other interesting variance in the CanVec data is that it does not indicate the type of any of the sources of water that it outlines. Which is it - a pond or a lake? A check around the Internet provides a ridiculous amount of referencing, discussion and argument as to what the difference between these two geographical items are. Some draw distinctions in terms of size, depth, movement or content while noting quite openly numerous examples that violate those criteria. Local knowledge in lieu of naming is likewise of limited use as a enormous water body in one place is a pond while another just a kilometer away at half the size is a lake.
To combat this, I have adopted the official naming scheme for water bodies as prescribed by the OpenStreetMap Wiki. Lakes are henceforth all bodies of water that are flowing (as in a stream or river) that are natural - that is, formed by local conditions independent of the influence of man. Ponds are artificial, man-made lakes that may now compose a portion of a regular waterway, but which is no less created either intentionally or otherwise.
