Octave Jacquinot started his engineering career in 1888 in Condom after having graduated from Ecole Polytechnique and Ecole des Ponts et Chaussées. Shortly later, he moved on to Bourg en Bresse to join the internal navigation service of the Saône Canal. Jacquinot there developed a simple entrance element for locks which was adopted all through France and contributed to the irrigiation techniques along the Saône River. In 1893, Jacquinot joined the Marne Canal service in Langres for the following 15 years. He designed its last 40 kilometers from the Marne to the Saône Rivers including 20 locks of which 8 were considered high. As for other canals, earth dams had to be erected for the canal water supply at its top elevation. Jacquinot therefore was in an intense contact with his colleague Galliot from Burgundy Canal.

Jacquinot eventually became a reputation for the design of earth dams, such as the large dam of Vingeanne or the Charmes Dam. The first structure is 1,250 m long and retains a water volume of 9 millions m3. It was executed from 1901 to 1905 and described in the 1909 paper published in the Annales. The works on the Charmes Dam were initiated in 1902; its height is 22 m resulting in the highest French earth dam for decades. This structure along with the particular anchorage elements is also described in the Annales. The technical knowledge of embankment dams was developed only from the 1930s, mainly by Karl von Terzagi (1883-1963). Jacquinot introduced also water intake towers in the reservoir of the Vingeanne site for a design discharge of 50 m3/s, a technique that developed into the morning glory spillway. In 1912, Jacquinot left the Upper Marne Department for Compiègne. He lectured and wrote a book on internal navigation at Ecole des Ponts. He was finally an Inspector General of his Corps from 1917.
