In many cases a surveyor must establish the boundaries of a parcel of land bordering a river, stream, lake or the sea. If the boundary is a river or stream, the rights that a person has are referred to as Riparian Rights. If the boundary is an ocean or a lake, then the rights are called Littoral Rights. Sometimes the rights relating to any water boundary are referred to as riparian rights but this terminology is inaccurate. The law of water boundaries varies considerably between jurisdictions. What follows is a general discussion designed to acquaint the reader with some of the issues related to water boundaries in some jurisdictions. The reader is encouraged to research the law in their own jurisdiction.
