# waternodedescriptionvalue This code list is used in association with the Description attribute which is present within the Water Node Feature Type. The code list describes the type of water node (for example, junction, source, sink, etc.). {% tabs %} {% tab title="v2.0" %} V2.0 of the code list was released on 28 October 2025. ## What's new? One new value has been added to this code list for v2.0: * Tidal Outlet – The end terminal of a set of one or more interconnected Water Links that does not have any downstream flow and which is in the foreshore or sea. For example, where a watercourse sinks into a beach, or enters the sea. The new value has a 'new' emoji (:new:)against it. One value has an updated definition: * Outlet – Definition has changed to remove references to a node finishing in the sea. | Label | Definition | | ------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Junction | A split in the network to indicate where three or more Water Link features meet at the same level. For example, confluences or bifurcations. | | Outlet | The end terminal inland of a set of one or more interconnected Water Links that does not have any downstream flow and which is not in the foreshore or sea. For example, where a watercourse sinks into the ground, or ends at a pond with no outflow. | | Pseudo | A location where the real world attribution of a watercourse changes that requires a Water Link to be split. | | Source | The start terminal of a set of one or more interconnected links that has downstream flow. For example, springs or collects. | | :new: Tidal Outlet | The end terminal of a set of one or more interconnected Water Links that does not have any downstream flow and which is in the foreshore or sea. For example, where a watercourse sinks into a beach or enters the sea. | | Unknown | An indicator on the water network to describe the accepted end of a watercourse that is not an Outlet or a Source. Examples being ends of drains with no identifiable direction of flow of water, or a pond or lake without any identifiable inflow or outflow. | | {% endtab %} | | {% tab title="v1.0" %} V1.0 of the code list was released on 29 September 2022. | Label | Definition | | ------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Junction | A split in the network to indicate where three or more Water Link features meet at the same level. For example, confluences or bifurcations. | | Outlet | The end terminal of a set of one or more interconnected Water Links that does not have any downstream flow. For example, where a watercourse sinks into the ground, or the point where a river enters the sea. | | Pseudo | A location where the real world attribution of a watercourse changes that requires a Water Link to be split. | | Source | The start terminal of a set of one or more interconnected links that has downstream flow. For example, springs or collects. | | Unknown | An indicator on the water network to describe the accepted end of a watercourse that is not an Outlet or a Source. Examples being ends of drains with no identifiable direction of flow of water, or a pond or lake without any identifiable inflow or outflow. | | {% endtab %} | | | {% endtabs %} | | --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.os.uk/osngd/code-lists/code-lists-overview/waternodedescriptionvalue.md?ask= ``` The question should be specific, self-contained, and written in natural language.
