Degree-days were defined as the <br /> <br />accumulated daily amounts that result from subtracting <br /> <br />32 degrees from the mean daily air temperature in <br /> <br />degrees Fahrenheit. The precipitation and evaporation <br /> <br />data were obtained from USWB records. The regression <br /> <br />follows. <br /> <br />DR = 59.335 (DD) - 4334.6 (AVPRCP) - 27,703 <br /> <br />where DR <br /> <br />= monthly diversion requirement in <br /> <br />acre-feet <br /> <br />DD = degree-days in degrees Fahrenheit <br /> <br />AVPRCP = average of precipitation measured at <br /> <br />the three locations in inches <br /> <br />The pan evaporation term was not statistically <br /> <br />significant at the 95 percent confidence level. The <br /> <br />correlation coefficient of the regression was 0.968, <br /> <br />and the standard error of estimate was 4,504 acre-feet <br /> <br />per month. <br /> <br />The reservoir operation was simulated using the <br /> <br />above equation to determine the monthly release rates. <br /> <br />The results of the operation simulation are summarized <br />
