Missouri River Recovery Management Plan Time Series Data Development for Hydrologic Modeling DRAFT Northwestern Division Omaha and Kansas City Districts Hydrologic Engineering Branch Engineering Division September 2016 USACE, Northwestern Division Omaha and Kansas City Districts DRAFT EXECUTIVE SUMMARY The purpose of the Missouri River Recovery Management Plan and integrated Environmental Impact Statement (MRRMP-EIS) is to develop a management plan that includes a suite of actions to meet Endangered Species Act (ESA) responsibilities for the piping plover, the interior least tern, and the pallid sturgeon using USACE authorities. The project involved the creation of a detailed suite of models for the Missouri River basin to evaluate existing condition and proposed alternatives. This report documents the development of the time series data sets for local inflows and evaporation to be used as input for the HEC-ResSim (ResSim) and HEC-RAS (RAS) models. Various data development methods were used based on available data sources at different locations. This report describes the data development methods and data sources in detail for the reservoir modeling time series input data sets of local inflows and evaporation used in the Upper Missouri River ResSim models, the Mainstem Missouri River ResSim models, the Kansas City District (NWK) ResSim models, and the local inflows for the RAS models. This report also describes the various routing methods used to determine the local inflow data sets. For a more detailed discussion on individual methods/results at a particular location, please see the pertinent full summary report. Information for all reports are included in the References section. The period of record (POR) selected for study purposes was initially set as January 1898 to December 2012. January 1898 was selected as the starting date to coincide with previous data development done as part of the Upper Mississippi River System Flow Frequency Study (USACE, 2003) completed in 2003. December 2012 was selected as the end date because that was the most recent data readily available during this phase of the study. After the POR time series data sets were completed and thoroughly reviewed, the decision was made to use only the data after January 1930. Several reasons were weighed to reach this decision, which are explained in detail in this report.
