74 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.—Continued [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).

However, some springs in the vicinity RM 69 and 70. Springs measured 4 ft 3 /s in 10/2002. Synoptic measurements made when flows recorded at USGS gage near Chiloquin were similar to long term average. Average 1970 measurement about 10 ft 3 /s larger than others. 0 OWRD 11/1/2000 Synoptic measurement Synoptic measurements made when flows recorded at USGS gage near Chiloquin were similar to long-term average fall flow. 0 OWRD synoptic measurements (2) 4 OWRD/USGS synoptic measurements (3) 50 OWRD synoptic measurements 11/2000, 10/2002 10/1970, 11/2000, 10/2002 Average Synoptic measurements on 10/1970 demonstrate gain of 30 ft 3 /s. Recent results do not concur with this finding.
