The Boshan Lake Dam soars above the horizon, linking Mountain Boshan and Mountain Ligang. 48m tall, 545m long, 8m wide on the top, the dam has a capacity of 0.62 billion m3. In Western Han Dynasty, it was where Langling County was established. Until now more than 2,000 years have passed. It is the joint part of Mountain Tongbai and Mountain Funiu. In the south-west rolls the imposing Mountain Tongbai, and in the north-west is grand Mountain Funiu.

The oval-shaped island looks like a whale. As the water rises and falls the island comes close or distant from the one in the south. On the eyot, there are extraordinary plant vies. In the southeastern part there is a botanical garden with more than 470 species, among which are rare plants as eucommia, yellow firs etc.

Up front on the left in the lake, there is a small island which looks like a mossback, namely the Linggui Island. Legend has it that a 10,000-year old tortoise saved Lan Caihe, one of the 8 immortals, who negligently delayed the tortoise's time to become an immortal. The tortoise had to wait more than 3,000 years and finally turned into an island.

The column reaches out from the water bottom and points towards the sky. On the left stands the primeval forest belt. Tall pine trees have formed a large canopy blocking all the sunshine, among which squirrels and pheasants are occasionally seen. Animals include jackals, wolves and badgers, and wild boars. The fruits are mainly wild haws, grapes, Chinese gooseberries and so on. The Boshan Chestnuts, a specialty of southern Henan, is among the most famous.

According to historical records, Da Yu, the hero of flooding control, once found Mountain Shetou was blocking the water flowing from the upper reaches and caused flood in summer. Emperor Yu and his soldiers were stationed on Liangzichong just across Mountain Shetou to do the digging. To commemorate the Emperor Yu, a temple was built on Liangzichong. There are only remains of the temple, while the tablet was preserved by the local people.

Cuizhu, literally bamboo, is a perennial plant of gramineae genus. The area is covered with various Bamboos, forming a beautiful valley. In addition, Boshan Lake is also a paradise of birds.

The drainage area of Boshan Lake is about 580km2, in which there are branches of rivers surrounded by rolling mountains with a vegetation coverage rate of over 99%. The favorable environment has formed beneficial conditions for various kinds of fish to reproduce. According to a survey, there are cuttlefish, yellow crappie, tortoise, horseshoe crabs, eels, shrimps, clams and mussels. The rarely seen fish in Central China include golden carps, breams, white eels and so on. The mandarin fish is among the best. Shaped like a crucian, but broader and fattier, its meat is extremely delicious and counts as one of the best fishes. The Boshan fish matches perfectly with Boshan water. Four dishes of stewed fish have won particular applauses from customers, namely stewed silver carp, stewed butterfish, stewed crucian and stewed tortoise.
