Lac de Pannecière is a lake in the department Nièvre in France.

So, ut's considered to be part of the EPTB Seine Grands Lacs.

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.

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.

This plant generates power from the waterfall created by the dam to produce electricity.
