Remarks on the history of the Prussian water-level gauging system in the 19th century

Motivated by the enactment of the first gauging instructions in Prussia 200 years ago, this article gives a short review on the history of the Prussian gauging system in the 19(th) century. It was implemented in the Kingdom of Prussia on February 13(th), 1810 and used as the most important basis for all public hydrological engineering administrations. These instructions were practiced until a new regulation was adopted in September 1871. Even though gauging observations had been carried out before 1810 in many places, the date February 13(th), 1810 may be described as the starting date of hydrological work in Prussia.
