'Fjord-lake') is a glacial lake on the island of the October Revolution of Severnaya Zemlya archipelago, administratively belongs to the Krasnoyarsk Krai of Russia.

Within the island, Lake Fiordovoye is located between the edge of the Karpinsky ice dome in the east and the slopes of the valley on its western side.

And due to the considerable depth of Fiordovoye, the fractions of the glacier are probably afloat in its basin, in which case the reservoir may also be classified as partially subglacial.

The floating ice remain until the next freezing of the reservoir, a significant part of it comes from the glacier in the east - the size of individual icebergs in the lake can reach 500 m (1,600 ft).

Three ice-dammed reservoirs in the southeast direction belong to the lake trough of Fiordovoye, they are separated from it by glaciers and can become its bays when they retreat.
