As can be seen, there are many years showing a deficit,
as could be expected considering the lower priority of irrigation demand and especially the high-stress situation of the Montedoglio reservoir; however,
the most interesting point is that once a critical deficit threshold has been set (e.g. 10%),
it is possible to infer the value of the reservoir volume at the 22th week (approx. 120 Mm3) below which it is probable that this threshold is exceeded,
with increases in the deficit almost directly proportional with the decrease of the available volume at the 22th week.
