average yield that allows for significant opportunities for carryover storage in wet to
slightly below average years, which will improve the HOA's ability to meet water
demands in dry years.

% of years
As shown in Table 10, with ownership of five FHL shares only twenty percent of the
years have water deliveries less than 133 acre -feet as compared to sixty percent of years
having less than 132 acre -feet with ownership of the current three FHL shares by the
HOA. Only ten percent of the years have water deliveries less than 106 acre -feet with
ownership of five FHL shares as compared to thirty percent of the years having less than
110 acre -feet available based on ownership of three FHL shares. With three FHL shares,
the chance that any single year and would only yield 78 acre -feet is 10 %. With five FHL
shares, the chance of a yield of less than 81 acre -feet drops to 19,'o each year. Therefore,
the risk is reduced ten -fold that the HOA will have only enough water deliveries in any
given year to cover reservoir evaporation and barely maintain fire - fighting reserves if
carryover storage from the previous year is minimal. The risk that the HOA will have
insufficient water supplies to meet its water needs without use restrictions is reduced
from sixty percent of the years to twenty percent of the years.
