During the Japanese colonial era, this manmade lake served as a reservoir for fighting fires. Lake Success（Chengkung Lake）was named after Lake Success in Long Island, New York, the temporary home of the United Nations from 1946 to 1951. The two small islands on the Lake are named Husin Island（湖心島）and Sigua Island（西瓜島）. The bridge going out to Husin Island was funded by Chai Ke Bin（翟克併）of the class of 1943, in honor of his brother, Tsinghua alumnus Chai Ke Gong（翟克恭）, after whom it is named. On Husin Island is the rustic Jimei Pavilion（寄梅亭）, more commonly known as the Husin Pavilion（湖心亭）. The Bajiao Pavilion（八角亭）and weeping willows along the pathway next to Lake Success further enhance the scenery.

In 2023, the restoration of Lake Success was successfully concluded. Generously supported by NTHU alumni, this initiative not only enhanced the water quality but also introduced improvements such as a waterfront pier, a lakeside promenade, and evening lighting. Kuo-lin Hu（胡國琳）（Department of Mathematics, 1984） generously sponsored the "Ling-ling and Kuo-lin Ecological Trail," "Zai-han Waterfront," and "Lai-yu Green Embankment." YN Chen（陳昱寧）（Department of Physics, 1974） contributed to the creation of "Yuning Island." Eric Tsai（蔡進步）（Department of Power Mechanical Engineering, 1981）, chairman of the NTHU Alumni Association, provided support for the construction of "Progress Pier," while alumni from the class of 1970 collectively contributed to the establishment of the “1970 Garden.”

Additionally, to preserve the ecological equilibrium of Lake Success, NTHU released a controlled number of over 1,700 fish, including black carp and grass carp. These fish are highly effective in eradicating algae and consuming mosquito larvae, consequently enhancing water quality, and restoring the brilliant charm of Lake Success with "clear water, birdsong, and romance".
