In this report are shown results of some experiments concerning the error of value of water equivalent of the deposited snow by snow sampler on the level land.From author's experiments, it seems that the measured values of water equivalent of the deposited snow vary considerably due to the difference of time, places and diameter size of the sampler used on the level land.Author points out from obtained results that much consideration should paid for the survey of water equivalent of the deposited water especially on the mountain area.
