A part of the streamflow construction and simulation process is the verification that a stochastic streamflow model reproduces those statistics which by design it should reproduce; the use of unbiased statistics is shown to be advantageous in this exercise. In addition, if a model reproduces statistics not used in the model‐parameter estimation process, its credibility is further enhanced. These concepts are illustrated, and the performance of a wide range of monthly streamflow models are compared using data for the upper Delaware River basin in New York State.
