  The Baikal Gigaton Volume Detector (Baikal-GVD) is a km$^3$-scale neutrino
detector currently under construction in Lake Baikal, Russia. The detector
currently consists of 2304 optical modules arranged on 64 vertical strings.
Further extension of the array is planned for March 2022. The data from the
partially complete array have been analyzed using a $\chi^2$-based track
reconstruction algorithm. After suppression of the downward-going atmospheric
muon background, a flux of upward-going neutrino events is observed, dominated
by the atmospheric neutrinos. The observed flux is in good agreement with Monte
Carlo predictions.
