The Long Range Study (LRS) Model is a simulation model developed in the 1960's develop and test criteria for operation of the Missouri River mainstem reservoirs through an extended period of hydrologic record. Historically, the model has been used to study different regulation scenarios to determine the feasibility of each, considering the goals and constraints of the system. For the Missouri River Master Water Control Manual Review and Update Study (the Study), the model was used to evaluate alternatives through a 96-year historic record. This paper summarizes the format and features of the LRS model, the revisions to the model, and the supplementary programs developed to aid in the Study.
