The fish pass made as part of the reconstruction of the Meaux dam will be located in the Cornillon Canal (currently unassigned) and will consist, from upstream to downstream: — of 7 concrete thresholds or partitions (Nos. 1 to 7) each consisting of a 1.50 m-wide bottom span and a half-triangular threshold. The positioning of the stems is alternated with the right/left bank. C is threshold number 1 which allows to control the flow through the fish pass. Upstream, a radiator is sunk at NGF 43.75 m. Each basin thus demarcated consists of a large concrete radiator with a homogeneous slope between two successive dimensions of chamfer; — of 12 concrete thresholds (Nos 8 to 19) with the same geometric characteristics as in the lock placed on the canal downstream of the lock. The canal is totally entangled in the bottom with a homogeneous slope between two successive scallops; — A damper structure, with a width of 10 m, making it possible to precisely locate the attractiveness zone of the downstream entrance of the pass.
