Abstract
The frequency and provision of the levels of the Ishim River during a period of 11 years of the 21st century are analyzed. The levels of the stream gauge, that are below zero, reoccurred most often during this period. The frequency is higher in the months when there is high water but the years when it happens are quite rare at the river of Ishim (it happened only three times during the period of 11 years that were studied). The levels of the frequency higher than 151 cm are quite few (less than 1%). High provision (more than 50%) is characteristic for the levels of the stream gauge, that are below zero. The lowest provision (less than 1%) is marked for the levels of 451-480 cm and 811-900 cm. The data on the frequency and provision of the levels of the Ishim River allow following a really threatening situation with the main source of drinking water supply of the town of Ishim.
