This report describes the Hydrologic Engineering Center-River Analysis System HEC-RAS water temperature models for five Missouri river reaches e.g., Fort Peck Dam to Garrison Dam Garrison Dam to Oahe Fort Randall Dam to Gavins Point Dam Gavins Point Dam to Rulo, NE and Rulo, NE to the mouth of the Missouri River. These models were developed based on calibrated HEC-RAS flow models that the Omaha and Kansas City Districts of U.S. Army Corps of Engineers USACE provided. Of five HEC-RAS water temperature models, three models were run for an 18-year period 1995-2012 for six alternatives in support of developing the Missouri River recovery program MRRP management plan ManPlan and environmental impact statement EIS. The HEC-RAS water temperature model results that were used to establish a baseline and management alternative scenarios are presented in this report. Likewise, the sources of model uncertainty are discussed in this report as well.
