We report the results of an analysis of the emission spectra of HII-regions in IC 10 ionized by star clusters and WR stars based on observations made with the 6-m telescope SAO RAS using MPFS field spectrograph and SCORPIO focal reducer operating in the slit spectrograph mode. We determine the masses and ages of ionizing star clusters in the violent star-forming region of the galaxy in terms of the new evolutionary models of emission-line spectra of HII-regions developed by Martin-Manjon et al. (2010). We estimate the amount of stars needed to ionize the brightest HII-region HL 111.
