Figure II-2 illdicates the locations within the upper basin where streamflow da';a were assembled for use in this study. Appendix provides a Ihting of the monthly runoff volumes for each of the used in the study for the 324 months of the 1953-1979 period. the bas 'I c Section D locations I I I I I I I I I I I I I I ' I I I I I After examin'ing available USGS records, the period 1953 through 1979 was selected for use in simulating project operations and evaluating water availability. In addition to the dry year of 1977, this period also includes the driest two-year and five-yealr periods, as well as the first, third, and fourth driest and third wettest single years. This period was also comparee to the 74-year records at the near-Meeker gage, and the statistical means and variances of the short-term and long-term records were found to be ~ithin a 90-percent confidence interval. Streamflow Data Correlations Within the 19S3-1979 period selected for the study, there were partial records of runoff from sub-basins in the Upper White River Basin. Some of the gaging point locations matched the locations of project facilities fJr storage and diversions from the 1972 Yellow Jacket Project Study. Streamflow information was required at these locations for the entire 1953-1979 period for use in the operation studies. The missing data were generated by :orre 1 at i ng the part i a 1 records with downstream gages. The North Fork fl)w records from the "at-Buford" gage, which are more complete, were used as the base data.

The sub-basin correlations were then checked for continuity to ensure that tile sum of all sub-basins on the North Fork equalled the total measured fl ow.
