<span style=\"font-family:'Times New Roman','serif';font-size:10pt;\">This article analyses annual runoff variation characteristics, including annual, inter-annual characteristics, tendency and mutation points, based on the runoff data series at Maduwang station in the BaheRiver. The main results are: the runoff has big inter-annual variability and its annual distribution is uneven; the tendency of the runoff is significant decline; the main periods of the runoff are 7 years, 19 years and 34 years, the period of 19 year is the most significant. The mutation of the runoff observed at Maduwang station took place around 1971.</span></span>
