There were many medium and small-sized lakes in the early Ming dynasty, which were linked each other by many deep or shallow canals in Jianghan plain.Along with the economic development, population growth, protective embankments in lakeside areas mushrooming and booming, there broke out more and more inundation after Chenghua(1465-1487).From the last phase of Zhengde (1506-1521) to early stage of Wanli (1573-1620),many medium-sized and small-sized lakes had been silting-up from the Yangtze River and Hanshui River, The spatial-temporal distribution of the lake evolution were different duo to the following reasons: Mire and sand from Hanshui River were deposited from the upper reaches to the lower reaches, while those from the Yangtze River were firstly silted up from the upper reaches to the lower reaches, then deposited back to the upper reaches.We can see this evolving trend clearly from the reducing and merging process of Hebosuo, an organization for levying piscatorial taxes.
