This is the general legend. Some maps are not standard and use slightly different conventions. The allocation to stream classifications is subjective. It is intended to reflect the ease with which the former streams can visualized.

An Existing Water Course which normally has a permanent flow, but includes some stretches that may dry up in a dry season. In some cases a map showing the historical watercourse will be shown in a sidebar.

A Dry Ditch which will be dry except seasonally and after a storm.

Ravine or Valley of former stream is clearly seen

Hazy Approximate location of former stream can be inferred from low points in topography.

Very Hazy, Lost or Inaccessible

Stream in Storm Sewer is used to show connections between stretches of existing water courses.

Trunk Storm Sewer There are storm sewers and sanitary sewers along most streets. With some exceptions only major sewers are mapped.

Storm Sewer Flow An orange arrow is use to show direction of flow of storm sewer or where a storm sewer empties into an existing water course.

Trunk Sanitary Sewer There are sanitary sewers along all streets. With some exceptions only major sewers are shown on reach maps. Many sanitary sewers also carry some storm water. See “Combined Sewers Overflows.”

More Complex Drains may have more than one colour. This is explained in the text.

Combined Sewer Overflows Storm overflow sewers. Arrow shows direction of flow as well as points where sanitary sewage may overflow into a water course during a storm. See sidebar on “Combined Sewers Overflows.”

Some Trails, Footpaths and Stairs are mapped in brown.

Other Linear Feature such as the shoreline of Lake Iroquois, the Beltline railway and the subway in the open are shown by purple lines.

Historic House locations of some existing and former historic houses.

Point of Interest The location of points of interest along the suggested walks are shown by red dots. Most will be linked to descriptive sidebars.

Parks General or open areas in Parks where wooded areas are shown as below. Light green.

Tree Covered Areas both in parks and in other areas along ravines. Includes some natural & naturalized areas . Medium green.

Cemeteries and some other features: Light purple

Contours: Contours are usually shown in grey and are included only for limited areas, particularly the ravines. Normal contour interval 5 metres.

**Scale indicator **: An orange-brown bar shows a distance of 400 metres or a quarter mile on the ground.
