Rainfall return levels at Bol'soe-Almaatinskoe-Ozero: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	38.9 mm (1.5 in)
5 years	47.6 mm (1.9 in)
10 years	52.9 mm (2.1 in)
25 years	59.2 mm (2.3 in)
50 years	63.6 mm (2.5 in)
100 years	67.7 mm (2.7 in)	Longer than the 53 years of record

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 53 years of values from 1936 to 1991.

A return level is an estimate. It is least reliable for the long periods, 50 and 100 years, and for any period longer than the record behind the fit, where the fit has to reach past the largest day actually observed. It is not a forecast.

The largest wettest-day totals in the fit: 63.1 mm (2.5 in) in 1954; 61.7 mm (2.4 in) in 1953; 61.6 mm (2.4 in) in 1963.
