72 Ground-Water Hydrology of the Upper Klamath Basin, Oregon and California Table 6. Estimated ground-water discharge to principal stream reaches in the upper Klamath Basin, Oregon and California. [Reach: River miles in Reach column are from Oregon Water Resources Department Klamath Drainage Basin Map, Map No. 14.6, 1971. Confidence level: Confidence levels represent a subjective assessment of the interval (plus or minus) that has a 95 percent probability of containing the true value. Confidence level categories are: 1, 10 percent; 2, 20 percent; 3, 30 percent; 4, 50 percent; 5, data insufficient to assess uncertainty. Subtotals rounded to two significant figures. Unless otherwise noted, values were derived by taking the average of estimated discharge in the fall (Sept, Oct, Nov). USGS synoptic measurement data from Leonard and Harris (1974).

Gains calculated from difference with upstream inflows. Average Majority of measurements approximately 1.5 mi from mouth. Miscellaneous measurement regression to Williamson R below Sprague R near Chiloquin, Oreg. (USGS site 11502500). Measurements at USGS site 11497000. Used data as miscellaneous measurement site due to large amounts of missing data. 2 4 1
