Precipitation data for Huntington Lake, in California, were analyzed to determine some of the seasonal distribution characteristics of precipitation and the relationships of the total seasonal Huntington Lake precipitation to Kings River runoff. Principal conclusions from the study are as follows: (1) During any particular winter-spring season, the quantity of precipitation subsequent to any given date is virtually independent of the quantity received up to that date; (2) the equation KRR = 0.736 HLP - 5.6 represents the relationship between the water-year Kings River natural flow runoff at Piedra in 100,000 acre-feet and the November-June Huntington Lake precipitation in inches, with a correlation coefficient of 0.92, and an average error of + 200,000 acre ft; and (3) by combining the relationship of (2) with river forecasts based on analyses by the California cooperative snow surveys and frequency curves of precipitation subsequent to the date of the forecast, it is possible to estimate with reasonable accuracy the chances of obtaining a given quantity of Kings River runoff. Curves for this purpose have been computed and are included.
