水塘相當深，顏色碧綠。塘底俾大大細細嘅沙石覆蓋，形成唔同嘅生態環境，適合各種魚類生存，包括香港少見嘅弓背青將、月鱧等。
The reservoir is quite deep and turquoise in color. The bottom of the pond is covered with fine sand and gravel, forming a different ecological environment, suitable for the survival of various fish, including the rare bowback of Hong Kong, the moon turtle and so on.
