We reanalyze the dataset collected during the years 1998--2003 by the deepunderwater neutrino telescope NT200 in the lake Baikal with the low energythreshold (10 GeV) in searches for neutrino signal from dark matterannihilations near the center of the Milky Way. Two different approaches areused in the present analysis: counting events in the cones around the directiontowards the Galactic Center and the maximum likelihood method. We assume thatthe dark matter particles annihilate dominantly over one of the annihilationchannels $b\bar{b}$, $W^+W^-$, $\tau^+\tau^-$, $\mu^+\mu^-$ or $\nu\bar{\nu}$.No significant excess of events towards the Galactic Center over expectedneutrino background of atmospheric origin is found and we derive 90% CL upperlimits on the annihilation cross section of dark matter.
