《水经注·卷三十》
涣水又往东南流过郡城北边、新城南边，又往东南流，在左边汇合明沟―沟水从蓬洪破往东南流，称为明沟―往下注入涣水。
涣水又东南径邵城北，新城南，又东南，左合明沟，沟水自蓬洪陂东南流，谓之明沟，下入涣水。
Hanshu continued to flow southeast, passing by the north of the county town and the south of the new city, and then continued to flow southeast, it joins the Minggou on the left - the water flows southeast from Peng Hongbo into Minggou - and then flows into Hanshu.
