OLMSTED.] VOLUME. 17 tion and the local discharges in the watershed are still in question^Mr. Henry Hawgood, Mem. Inst, of C. E., who has made a careful studyof the physical conditions existing in the watershed of Kern River,more particularly in that of the North Fork, has estimated the annualprecipitation for the North Fork above Isabella at inches, witha run-off of inches. This would give a mean annual flow ofthe North Fork of 982 second-feet. Mr. Hawgood estimates the rain-fall of the entire basin at 23 inches, and the mean run-off at On this last assumption the mean discharge of Kern Riverat its mouth would be 1,350 second-feet. As a fact, however, for thelast five years (1895-1899)—a period of exceptional drought in thebasin—the stream has had a mean annual discharge at First Point ofMeasurement, near Bakersfield (see map, PL III), of 864 second-feet,or 64 per cent of the normal assumed by Mr. Hawgood.
