Its construction was planned following major floods of the Seine, namely that of 1910. The lake-reservoir was declared of public utility by a decree of the September 8, 1929. So, ut's considered to be part of the Great lakes of Seine.

Work only actually began on September 29, 1937, but was interrupted at the start of WWII, before resuming in May 1946 and completed in December 1949. During periods of high activity, up to 550 workers worked on the site (they were housed in a newly constructed workers' town, as the area has low population and most workers came from afar, without housing). Its construction also included the creation of 16 km of roads and 6 bridges.

Two hamlets were engulfed during the impoundment of the reservoir: "Pelus" (entirely) and "Blaisy" (partially). Remains can still be seen during the annual partial emptying, or during the complete decennial emptying: piles of stone, the Yonne and the Houssière and the old stone bridges spanning them, the roads that crossed the hamlets, etc.

A hydroelectric plant managed by EDF was set up in 1950. This plant generates power from the waterfall created by the dam to produce electricity.
