The watercourse identification map (WIM) series shows the known extent of geographic features that are managed under the Water Act 2000 section 5AA: watercourses, drainage features, downstream limits, lakes, springs.
A drainage feature means -
(a) if a feature is identified on the watercourse identification map as a drainage feature - the feature identified on the map; or
(b) otherwise - a natural landscape feature, including a gully, drain, drainage depression or other erosion feature that -
(i) is formed by the concentration of, or operates to confine or concentrate, overland flow water during and immediately after rainfall events; and
(ii) flows for only a short duration after a rainfall event, regardless of the frequency of flow events; and
(iii) commonly, does not have enough continuing flow to create a riverine environment.
Example for paragraph (b)(iii) -
There is commonly an absence of water favouring riparian vegetation.
