monthly records throughout the study period. Regression analyses were developed to fill <br />missing data for these gages. The analyses resulted in good correlations and reasonable <br />hydrographs are produced when used to fill missing values. The input command files to TSTooI <br />are provided in Appendix A. <br />Comments and Concerns <br />The selected study period is 1950 through the most current year available. The TSTooI input <br />command files were provided for the period of 1950 through 2002, the most recent data available <br />at this time. In the future, these command files can be modified to include additional years of <br />data. As more data become available, the results from filling missing data may change slightly, <br />however it is unlikely to significantly affect the regression correlations. <br />Appendices <br />Appendix A - TSTooI Command Files <br />Attachments <br />Appendix A - SPDSS Final Memo, Methods for Filling Missing Streamflow Records (In <br />Support of Task 2 -Identify Key Streamflow Gages and Estimate Streamflows for Missing <br />Records) <br />Task2.doc 27 of 30 <br />
