Construction of the first large reservoir on the Crimean peninsula north of Bazarchik (now Post Office) on the beam of Bazar-Jilga, which flows into the river Alma (length 87.8 km, catchment area 635 km2), was carried out in 1925 under the project of the regional department of water management. The volume of the reservoir named Alminskoye (Bazar-Jilga) was 1.7 million m3, which allowed the irrigation of 1.8 thousand hectares of land. In 1927 on the Crimean peninsula there were two catastrophic earthquakes (June and September) with magnitudes 6.0 and 6.8.
In 1934 the reconstructed complex of GTS of the Alminsky reservoir was put into operation. The reservoir volume was 6.0 million m3; Ground dam height - 20.2 m; Dam length - 220 m; Width along the ridge is 7.45 m.
In 1974 - 1976 the reconstruction of the complex of GTS of the Alminsky reservoir was carried out. During the period of operation of the Almin reservoir, the norms of seismic construction in the USSR and the Russian Federation were changed 11 times.
The issues of seismic stability of the soil dam of the Alminsky reservoir in accordance with the requirements of SP 14.13330.2018 "Construction in seismic areas," which shows the criterion conditions for the operated hydraulic structures, are considered in the work.
