The reservoir covers an area of 31,225.27 acres, with a total capacity of 100.3 million cubic meters, a dead storage capacity of 4.64 million cubic meters, a hingli storage capacity of 95.66 million cubic meters, and an annual water supply capacity of 81.21 million m3, a design level of 12.471m, a dead storage level of 6.471m, a storage area of 16.89 square kilometers, and an enclosing embankment of a total length of 16.61km. the reservoir's annual evaporation of 2.06 million cubic meters is about 20% of the total storage capacity, and the annual evaporation is about 20% of the total storage capacity. The annual evaporation of the reservoir is 2006 million cubic meters, accounting for about 20% of the total reservoir capacity, and the annual infiltration is 8.32 million cubic meters, accounting for about 8.3% of the total reservoir capacity.

Dalangdian Reservoir is the main source of water supply for Cangzhou City, and currently draws water for storage once a year, and the routes for drawing water include drawing yellow water into the precipitation and Wangda water diversion, the former from Liaocheng, Shandong Province, and the latter from Wangquan Reservoir in Baoding. Since put into use, the Daliandian cumulative storage 12 times, *** storage of nearly 600 million cubic meters of water, of which 11 times is the introduction of yellow into the precipitation, only in 2005 to use the Wangda water diversion storage once.

Dalangdian main water supply target for the city of Cangzhou, the introduction of large into the harbor along the reservoir around Nampi, Botou and other counties. Since the completion of the cumulative water supply of more than 370 million cubic meters.

In order to ensure the safety of urban water supply, Daliandian has been fully closed management in recent years. And because of greening and other measures, the reservoir water quality indicators have been maintained in the surface water Ⅱ class water quality standards, better than the drinking water source Ⅲ water quality requirements.
