We present the results of a one year monitoring of absorption and scattering lengths of light with wave length 375÷532nm within the effective volume of the
Baikal-GVD deep underwater neutrino telescope. The measurements were
performed using a dedicated device, BAIKAL-5D, which was installed
during the 2020 winter expedition at a depth 1250 m. The device has a shaded point-like isotropic light source with spectral resolution about 3nm. A wide angle light receiver is moved by a stepper motor so that the distance between the receiver and the light source changed between 0.9 and 7,4 m. Absorption and scattering lengths were measured every week in 6 spectral points. Shot-time variation of absorption and scattering length was estimated.
