<br />OflD3B3 <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />Table 13 provides a summary of the analysis. Column entries in Table <br />13 are described as follows: <br /> <br />I. Precipitation Beginning Date - The first day of a rainy period in <br /> <br /> <br />the Mancos River basin, resulting in a sharp rise in the river flow <br /> <br /> <br />at the gage near Highway 666. <br /> <br />2. Mesa Verde and Mancos Precipitation - Total measured precipi- <br /> <br /> <br />tation during each rainy period for which a sharp rise was record- <br /> <br /> <br />ed at the Mancos River near Highway 666. Summaries of monthly <br /> <br /> <br />Mesa Verde and Mancos precipitation are provided in Tables 14 and <br /> <br />15. <br /> <br />3. <br /> <br />Total Flow at Highway 666 - Total historic flow of the Mancos River <br />near Highway 666 during the period when a sharp rise in the flow <br />was recorded. The period of time ranges from the beginning of <br />the runoff event until the flow receded to its approximate initial <br />level. <br /> <br />4. Base Flow at Highway 666 - The total base flow during the period <br /> <br /> <br />is considered to be the average flow at the gage for the conditions <br /> <br /> <br />before and after the rise occured. <br /> <br />5. Incremental Flow at Highway 666 - The incremental flow is the <br /> <br /> <br />total flow less the base flow. In other words, the incremental flow <br /> <br /> <br />is equal to the volume of water at the gage resulting from the short- <br /> <br /> <br />term runoff event. <br /> <br />6. La Plata River Incremental Flow - Short-term flows as measured <br /> <br /> <br />at the La Plata at Hesperus gage were calculated for each rainy <br /> <br />period. As shown in Table 13, a rise in the La Plata River did not <br /> <br /> <br />always occur during the period when a sharp rise for the Mancos <br /> <br /> <br />at Highway 666 was observed. <br /> <br />-34- <br /> <br />...!<._<d <br />
