80 <strong>Ground</strong>-<strong>Water</strong> <strong>Hydrology</strong> <strong>of</strong> <strong>the</strong> <strong>Upper</strong> <strong>Klamath</strong> <strong>Basin</strong>, <strong>Oregon</strong> <strong>and</strong> California<br />

Table 6. Estimated ground-water discharge to principal stream reaches in <strong>the</strong> upper <strong>Klamath</strong> <strong>Basin</strong>, <strong>Oregon</strong> <strong>and</strong> California.—Continued<br />

[Reach: River miles in Reach column are from <strong>Oregon</strong> <strong>Water</strong> Resources Department <strong>Klamath</strong> Drainage <strong>Basin</strong> Map, Map No. 14.6, 1971. Confidence level: Confidence levels represent a subjective assessment<br />

<strong>of</strong> <strong>the</strong> interval (plus or minus) that has a 95 percent probability <strong>of</strong> containing <strong>the</strong> true value. Confidence level categories are: 1, 10 percent; 2, 20 percent; 3, 30 percent; 4, 50 percent; 5, data insufficient to assess<br />

uncertainty. Subtotals rounded to two significant figures. Unless o<strong>the</strong>rwise noted, values were derived by taking <strong>the</strong> average <strong>of</strong> estimated discharge in <strong>the</strong> fall (Sept, Oct, Nov). USGS synoptic measurement<br />

data from Leonard <strong>and</strong> Harris (1974). Abbreviations: BOR, Bureau <strong>of</strong> Reclamation; CDWR, California Department <strong>of</strong> <strong>Water</strong> Resources; Cr, Creek; ft 3 /s, cubic feet per second; Hwy, Highway; mi, mile; NA,<br />
