brief introduction

Dangjiacha dammed lake is located in the southwest of Xiji County, 38 kilometers away from the county, in Zhenhu township,

Dangjiacha barrier lake, the second largest earthquake Lake in Asia, is also the largest earthquake barrier lake in Guyuan area. It is like a bright crystal bead, inlaid in the vast Loess Plateau.

In December 1920, a rare earthquake of magnitude 8.5 occurred in Xihaigu. Dangjiacha village, located in the loess hilly area, has been 80 years since the huge underground vibration caused landslides in the East and west sides of the village, blocking the ravines and forming weirs.

the measure of area

The original area of dangjiacha barrier lake is about 80 square kilometers. The existing water surface is 600 meters wide from east to west, 3110 meters long from north to south, covering an area of 1.866 million square meters, with an average water depth of about 12 meters and a total volume of about 16 million cubic meters. Its water quality is bitter and salty, and its salinity is high. It can neither be eaten nor watered. Crucian carp, carp and grass carp grow in the weir, and the largest fish is more than 10 kg. There are a lot of reeds planted artificially in the shallow water near the weir.

Landscape of barrier lake

The Haiyuan earthquake in 1920 not only brought disaster to mankind, but also left a rare and precious natural heritage - earthquake sites. "Ten li long gorge, rippling blue waves, ducks and geese playing in the water, swallows flying and fish leaping..." This is the second largest earthquake Lake in Asia - dangjiacha barrier lake. The lake water is clear and clear, the reed rippling with the wind, surrounded by green mountains, green mountains and deep valleys, which constitute a natural picture of mountains and rivers recovering, surrounded by mountains and water, and the blending of mountains and rivers. Scholars praise "the beauty of Sand Lake in the north, and the wonder of Zhenhu Lake in the South".

Zhenhu basin is rich in animal and plant resources. There are more than 30 kinds of animals under the first and second level national protection and the autonomous region protection. Zhenhu breeds a kind of peculiar fish - color crucian carp, because only Xiji County has this kind of crucian carp, so it is called "Xiji color crucian carp". Compared with common crucian carp, this kind of color crucian carp is smaller, the bigger one is only half a Jin, and the smaller one is about one or two. There are pure white, pure red, pure black, golden or black purple, there are also five colors or mixed with a variety of colors. Strangely, this kind of fish only grows in a few dammed lakes, and only in the local and local water environment can it maintain its color for a long time. If it changes the environment, it will gradually lose its original color, which is of great ornamental value and scientific research value.

The earthquake remains of Zhenhu lake are obvious and the scenery is charming. 43 earthquake dammed lakes are scattered in the Lanni River Basin like beads. The legend of water monster has added some magical color. It is of great value for scientific research, tourism and exploration. It has been approved as "national earthquake landslide dammed lake site" and autonomous Wetland Nature Reserve. Zhenhu lake has been built into an upper water park. You can take a cruise in the lake and watch groups of rare birds such as wild ducks, sea eagles, red footed falcons, great tits, owls and so on playing around. You can enjoy the fun of Jiangnan Water Town.
