4.3 Water and marsh

This group includes both open water and special types of vegetation caused by the presence of water (marsh). The classification is important because it indicates the degree of hindrance to the runner and provide features for map reading and control points. A black line around a water feature indicates that it cannot be crossed under normal weather conditions. In dry areas the features listed in this section may only contain water in some seasons.

	301 Lake Large areas of water are shown with dot screen. Small areas of water should be shown with full colour. A black bank line indicates that the feature cannot be crossed. Colour: blue 50% (60 lines/cm), black.
	302 Pond Where the lake or pond is smaller than 1mm2 on the printed map, the bank line is omitted. Colour: blue.
	303 Waterhole A water-filled pit or an area of water which is too small to be shown to scale. Location is the centre of gravity of the symbol, which is orientated to north. Colour: blue.
	304 Uncrossable river An uncrossable river or canal is drawn with black bank lines. The bank lines are broken at a ford. Colour: blue 50% (60 lines/cm), black.
	305 Crossable watercourse A crossable watercourse, minimum 2 m wide. The width of watercourses over 5 m wide should be shown to scale. Colour: blue.
	306 Crossable small watercourse A crossable watercourse (including a major drainage ditch) less than 2 m wide. For better legibility a ditch in a marsh should be drawn as a crossable watercourse (305). Colour: blue.
	307 Minor water channel A natural or man-made minor water channel which may contain water only intermittently. Colour: blue.
	308 Narrow marsh A marsh or trickle of water which is too narrow to be shown with symbol 310 (less than ca. 5 m wide). Colour: blue.
	309 Uncrossable marsh A marsh which is uncrossable or dangerous for the runner. A black line surrounds the symbol. Colour: blue, black.
	310 Marsh A crossable marsh, usually with a distinct edge. The symbol should be combined with vegetation symbols to show runnability and openness. Where a small marsh area should be combined with either 403/404 it is permitted to use 401/402 to improve legibility. Colour: blue (with yellow/green).
	311 Indistinct marsh An indistinct or seasonal marsh or area of gradual transition from marsh to firm ground, which is crossable. The edge is generally indistinct and the vegetation similar to that of the surrounding ground. The symbol should be combined with vegetation symbols to show runnability and openness. Colour: blue.
	312 Well Wells and captive springs, which are clearly visible on the ground. Colour: blue.
	313 Spring The source of a stream with a distinct outflow. The symbol is orientated to open downstream. Colour: blue.
	314 Special water feature A special small water feature. The definition of the symbol must always be given in the map legend. Colour: blue.
