Bien Ho Lake of Pleiku

The plateau around Pleiku has no sea. But it does have a Biển Hồ, a name that means Sea Lake.

It sounds odd, a lake that people call a sea. Once they stand in front of it, the name makes sense. The water spreads over about 240 hectares. Clouds and pine forest are reflected in it, and the surface turns one unusual shade of blue-green, not like an artificial lake and not quite like an ordinary one. Tourism writers call the lake and Chư Đăng Ya the eyes of Pleiku. That is a literary phrase, not an official geographic name, but it catches the feeling of looking at the water.

The Gia Rai call the lake Ia Nueng. The Bahnar call it Tum Tơnueng. The most common name in Vietnamese is Tơ Nưng. Each name leads into a different layer of culture. The Gia Rai are one of the peoples of Vietnam's Central Highlands.

In scientific terms, the lake is the trace of an ancient volcanic crater that went quiet millions of years ago. Records from the Biển Hồ commune say the lake floor has three hollows. Two large ones connect and reach about 16 meters deep. The third is about 12 meters deep. An old rumor said the lake had no bottom. In fact, the floor has been surveyed with echo sounders, and its shape is well known. Still, the rumor shows how long this place has stirred awe, and some fear, in people.

Just as important, the lake is a real source of household water for the Pleiku area. It holds about 25 to 30 million cubic meters, so it is more than a view to admire. It is a working supply of water. The calm blue-green surface quietly feeds a whole city every day.

Biển Hồ was recognized as a national scenic site on November 16, 1988, by a decision of the culture ministry.

The lake has a cultural layer too. The name Tơnuêng is tied to a Gia Rai legend about an ancient village that was buried, and the tears of the survivors turned into the lake. It is a legend, not a geological fact. Yet it explains why this water is more than a place to look at scenery. For the Gia Rai it has been part of cultural memory since long before anyone spoke of tourism.

In the southeast corner of the lake lies the Biển Hồ archaeological site, linked to people of the late Neolithic to the early metal age on the Pleiku plateau. According to the commune's records, the main excavation took place in May 1993. The Gia Lai provincial museum now displays some objects from the site. So this one place holds volcanic geology, a household water supply, a folk legend, Gia Rai culture and the traces of prehistoric settlers. Few places gather so many layers of history into a single lake of 240 hectares.

On a point of land looking out over the lake stands a statue of Quan Thế Âm, the bodhisattva of compassion. It is made of white marble, stands 15 meters tall, and was restored in 2018. It is a spiritual stop within the scenic grounds, and it often draws even people who are not Buddhist, for the beauty of its proportions and the stillness of its setting.

Biển Hồ lies only about 7 kilometers from the center of Pleiku, along a road running between two rows of pines. Near the end, the pine forest opens, and the water suddenly spreads out in front, so wide and so blue-green that you have to stop and look.

Whether it is called Biển Hồ or Ia Nueng, every name leads to the same water. Here the visitor stands on traces of geology millions of years old, above a lake that quietly feeds a city every day. And beneath the calm blue-green surface lies a depth of memory that even its names cannot fully tell.
