The design of hydraulic structures for the upstream migration around dams as the vertical slot fishways is very important for the engineers for applying the European Water Directive (2000/60/CE) or the French law (Lema), One of the main parameters for the design is the discharge coefficient. For guaranteeing this coefficient, an evaluation of the uncertainties has been carried out. This approach allows the identification of the different parameters which influence this measurement. Among all the parameters, the water depth and the slope measurements are the major quantities which influence the more the results of the measurements. The evaluation of the uncertainties in laboratory will be extended to the measurements of other quantities.
