Sea Eye Lake
Lake in Russia
The Mushyl lake (Mari: Мӱшыл йер, Müšyl Jer), nicknamed the Sea Eye (Russian: Морской Глаз, Morskoy Glaz) is a minor karst lake in Shariboksad, Volzhsky District, Mari El, Russia. Located at the foot of the hill its bright green water is extremely deep (38.5 m) compared to the surface area (45x50 m).
In 2022 the water level has dropped, leaving the lake nearly dried.[3]
