This code list is used in association with the Description attribute which is present within the Water Link Feature Type. The code list describes the type of link (for example, canal, drain, still water, watercourse, etc.).
Label
Definition
Canal
An artificial watercourse originally created for inland navigation.
Canal Feeder
Usually an offshoot from a stream or small river running into a canal, thus keeping it filled with water.
Drain
An artificial watercourse whose primary purpose is the removal of excess water from a localised area.
Foreshore
A water network link that crosses foreshore or salt marsh but does not follow a particular defined course.
Leat
An artificial channel that is constructed to convey water from one location to another.
Lock
An enclosure in a canal or river with gates at each end, allowing boats to move from or to a higher or lower section by raising or lowering the water level between the gates.
Marsh
A water network link that crosses fresh water marsh but does not follow a particular defined course.
Overflow
A watercourse, normally artificial, that allows excess water to flow from another watercourse, a reservoir or a facility such as a factory or power station.
Reservoir
A watercourse passing into or through a body of water that has been created or modified to facilitate the storage of water for irrigation, water supply, hydro electric power generation, industrial processes and similar.
Sea
An area of sea represented as a water network feature to provide a terminal for inland and tidal rivers.
Still Water
A body of non flowing water not affected by normal tidal action including features such a lake or pond.
Watercourse
A body of water where the water contained within flows from one end to the other, such as a river or stream. Includes watercourses that have been artificially modified specifically for the passage of boats or ships, for example, through the addition of lock gates, weirs and deepening existing natural channels.
