Abstract The performance of five stochastic models for generating annual streamflow sequences is evaluated based on applications to four Utah streams. Model performance is evaluated in terms of preservation of annual persistence statistics; cost and ease of model use; magnitude of the economic regret associated with drought-related agricultural losses; and comparison of reservoir capacity and critical drought design parameters. The ARMA-Markov and ARMA models are judged to be best overall in terms of preserving short- and long-term persistence. The broken line model is judged to be best in terms of minimizing economic regret. An initial model choice procedure is proposed.
