In this talk I will present the status of construction and operation of neutrino telescope in Lake Baikal, the detector Baikal-GVD of gigaton volume. In particular, basic elements of the GVD, data processing and preliminary results, and as well, main features of the Baikal-GVD site and optical properties of water will be shown. Off-line analysis of two famous cosmic events, GW170817 and IC170922A, and the beginning of multi messenger program are discussed.
