The melting of accumulated winter snow on the upper
section of the watershed is the principal source of Basin runoff.
In this regard, records show that 79 percent of the water yield of
the basin originates on only 11 percent of the watershed area lo-
cated above the junction of the South Fork with the main White
River. Also, over 58 percent of this occurs during the three snow-
melt months of Eay, June and July. Fifteen percent of the remaining
21 percent is runoff which originates in the Upper Division below
the junction of the South Fork. Only 6 percent of the basin run-
off originates on the watershed of the Lower Division. The Upper
Division also contains 72 percent of the presently irrigated land
and a major portion of the basin land suitable for irrigation.
