Definition
A watergang is a channel, trench, or artificial watercourse constructed to carry or drain water — most commonly used in the context of drainage works in low-lying or marshy land. The term appears in early English legal texts to describe the right to, or the physical structure of, such a drainage channel, particularly in fenland and coastal regions where water management was essential to land use.
Common Language
Modern common usage (Wiktionary): A mill race — that is, a channel directing water to power a mill wheel.
The legal use of watergang is narrower and more specifically tied to drainage rather than water power. A mill race directs water purposefully to a mechanical end; a watergang in legal texts is primarily a drainage feature for land reclamation and flood control. The two structures may be physically similar, but the legal rights, duties, and disputes attached to each arise from different bodies of law — drainage law versus water power and riparian rights. Researchers who encounter watergang in a legal document should not assume a milling context without additional evidence.
Why It Matters in Research
Watergang is a term researchers will encounter almost exclusively in historical English property and land law materials, particularly those touching on drainage rights, common law water rights, and fenland administration. It surfaces in older conveyancing documents, manorial records, and early statutes dealing with marsh drainage — notably the works of Commissioners of Sewers, who administered drainage law in England from the Tudor period onward.
Researchers should be aware that watergang overlaps substantially with easement law as applied to watercourses, but the term itself does not appear in modern statutory frameworks. If you encounter it in a historical deed or pleading, it signals a drainage servitude or a physical drainage feature that may have legal consequences for land title, access, or maintenance obligations. The disappearance of the term from modern usage creates a research gap: modern cases dealing with the same subject matter will use terms like "drainage channel," "watercourse," or "drain" without the historical label.
Black's citation to Cowell — that is, John Cowell's *The Interpreter* (1607), a legal glossary of technical and archaic terms — flags watergang as already specialized vocabulary by the early seventeenth century. Researchers using Cowell as a secondary source should treat it as a period reference, not a current authority.
Historical Dictionary Support
Black's Law Dictionary traces the term to Saxon origins, defining it as "a trench or course to carry a stream of water, such as are commonly made to drain water out of marshes," citing Cowell. This is a thin but accurate entry — Black's is essentially relaying Cowell's seventeenth-century gloss rather than developing an independent legal definition, which reflects how marginal the term had become by the time Black's was compiled.
Cowell himself was recording a term already in legal use for drainage administration in marshy English counties, particularly in the East Anglian fens and similar low-lying regions. The legal significance was never in the word itself but in the rights and duties attached to the physical structure it named — who bore responsibility for maintenance, who held the right to flow water through it, and how disputes over blockage or diversion were resolved.
No modern legal dictionaries carry the term as a live entry. Researchers should treat watergang as a historical-technical term whose legal content is best reconstructed through its surrounding documentary context rather than through dictionary definition alone.
Jurisdictional Note
Watergang as a legal term is specific to English law and its historical administration of fenland drainage. It does not appear as a term of art in Scots law, Irish law, or American law. Researchers working in those jurisdictions will find no direct equivalent entry and should instead pursue watercourse, drainage easement, or ditch rights through jurisdiction-specific sources.
