FIELD: construction.
SUBSTANCE: invention relates to hydraulic engineering. The method to dry a storage pond on a river arranged as a result of weir construction on it includes arrangement of two dams in the water area of the storage pond, which are aligned along the bed of the river flowing between these dams, ends of which reach the riverhead of the storage pond. In the riverhead of the storage pond the ends of dams are created with gaps to its coasts, and lower ends, not reaching the storage pond weir, turn towards the riverbed middle in plan, joining each other there. For passage of water from the riverbed they develop a tunnel or tunnels on the bottom of the storage pond or below its bottom with an outlet to the river bed along its flow downstream the storage pond weir.
EFFECT: makes it possible to dry a storage pond with subsequent use of dried territories.
