A watercourse is the channel that a flowing body of water follows.[1]

In the UK, some aspects of criminal law, such as the Rivers (Prevention of Pollution) Act 1951, specify that a watercourse includes those rivers which are dry for part of the year.[2]

In some jurisdictions, owners of land over which the water flows may have rights to some or much of the water in a legal sense.[3] These include estuaries, rivers, streams, anabranches[4] and canals.[5] If it is navigable, it is also a "waterway".[1]
