To study the spring flood regime of the Aley River the observation data from the cross sections over the recent 30 years was used. The control of the Aley River flow-off by the Gilyovskoye water-storage reservoir enabled an integrated use and protection of the Aley River basin water. The rise of water plane during the flood is intense, but often slows down with the return of cold weather and uneven snowmelt. A multiple-peaked flood pattern is also caused by abundant precipitation in the river basin. During ice-drift almost every year there are ice jams causing a temporary rise in water level by 2-3 meters. Low water is observed in June. It is difficult to define the travel tiltmeter of flood peak in the cross sections because of a wide range of travel tiltmeter values. That is caused by various ice conditions in the riverbed and snowmelt in the catchment area. The rain flood peaks lag is representative, as the rain precipitation upstream is greater than downstream, and the process is clearly monitored. The flow velocities from Gilyovo to Lokot village were taken as at Lokot cross section, and from Lokot to Aleysk were defined as the arithmetic mean at those cross sections. The developed measures for optimizing flow-off are related to the issues of flooding and the Aley water discharge reduction to the Ob, and more equal distribution of river flow-off, both temporal and spatial.
