The lake occupies an inter-hill depression and stretches from north to south [5] . The maximum length (from southwest to northeast) reaches 6 km, width up to 2.3 km. The coast is swampy.

In connection with the regulation of the Volga river flow, the hydrological regime of the reservoir has undergone significant changes. If in 1916, ilmen was a well-flowing, rather deep body of water (up to 2 m deep), not overgrown with aquatic vegetation and with various soils (sand, gray silt, etc.), then by 1970, due to a decrease in water content in summer, it was already almost 98 % of the surface of ilmen was covered with thickets of submerged vegetation [9] .
