Observations of the river regime were carried out at the hydrological post near the village of Znamenka ( 1950 - 1968 ). In the mode, there are: spring floods (during which 50-60% of the annual flow passes), summer-autumn rain floods (up to 3-5 per season lasting from 2 to 10 days), summer-autumn and winter low water . The average perennial layer of annual flow in the pool is 56 mm. Spring flood usually begins in early April and lasts an average of 31 days. The first ice phenomena are observed in the 2nd – 3rd decade of October, and the freeze-up is at the end of October - mid-November. In some years, the river freezes ( 1964 ). Average long-term low flow rate - 0.14 m³ / s. Water is moderately hard. The pool has 8 ponds with a total area of mirrors - 94.8 hectares. Water resources are used for irrigation, irrigation of pastures, recreation. The total water consumption reaches 43% of the annual flow (3.6 million m³).
