Gokyo Lakes

Gokyo Lakes are spectacular turquoise lakes in the beautiful Everest region. They are located in the Khumjung village in the Sagarmatha National Park region of eastern Nepal. Six Gokyo lakes are located at 4,700-5,000 m above sea level.

These lakes are oligotrophic, meaning there are fewer nutrients and, thus, low productivity. However, they also remain crystal clear and are stunning due to this factor. Oligotrophic lakes are common in these extremely cold Himalayas regions.

Moreover, these highest freshwater lakes are a jewel of the Everest region. The Gokyo Cho is the main one of the six lakes. It is widely known as Dudh Pokhari among locals. However, the largest one of the lot is Thonak Lake. These lakes and the surrounding wetlands are also listed as Ramsar sites.

Furthermore, the Gokyo region used to be a yak grazing site. However, you will find a small village settlement in the area now. The Cho Oyu Mountains reside just above the village. There is Mt Everest in the east of the village and Thamserku to the south. Read more to learn about the Gokyo Lake system and other details.

The Gokyo Lake System

Gokyo Ri Sagarmatha National Park

Gokyo Lakes is an oligotrophic lake system located on the premises of the Sagarmatha National Park. Gokyo Cho is the main lake over 42.9 ha (106 acres). It remains in the eastern part and is widely known as Dudh Pokhari.

Moreover, the largest lake is Thonak Cho, spread over 65.07 ha (160.8 acres). The other lakes include Gyazumpa Cho at 29 ha (72 acres), Tanjung Cho at 16.95 ha (41.9 acres), and Ngojumba Cho at 14.39 ha (35.6 acres). These lakes are hydrological as they are permanent high-altitude freshwater lakes.

Furthermore, the lake’s primary water source comes from the seepage of the Ngozumpa glacier. Besides that, streams from the Renjo La Pass and the Ngozumpa glacier on various sides contribute to the lake’s water resource. The total Gokyo Lake remains spread over 196.2 ha (485 acres).

Hence, the lake’s freshwater comes from Himalayan glaciers. Similarly, these lakes release water to the Dudh Kosi River flowing in the region. There are two smaller lakes, namely Taujon Lake and Longabanga Lake, through which they release the water to the Dudh Koshi.

The deepest lake among these Gokyo lakes is the Fourth Lake (Thonak Cho) which has a depth of 62.4 m. The next deepest lake is the Gokyo Cho at 43 m. While the researchers have not found any linkage between these Gokyo lakes, they have concluded on an underground seepage water connection hypothesis.

Another important factor is that the Gokyo Lake system lies ecologically fragile. The Ngozumpa glacier and its outburst are a grave danger to lakes. Hence, it is a naturally vulnerable and unstable zone.

The Religious Significance of the Gokyo Lakes

The Gokyo Lakes are an important religious heritage site in the Everest region. There are incredible festivities on Janai Purnima, where Hindus and Buddhist pilgrims gather to dip in the lake’s holy waters. It is generally celebrated in the August month of the Autumn season.

The lake is also widely considered the abode of ‘Nag Devata’ (Snake God). There you can find a temple of Lords Vishnu and Shiva at the western point of the lake. Many of the 7,000 tourists who visit the lake annually are religious pilgrims.

Tourism in the Gokyo Region

The Gokyo region has slowly gained popularity among trekkers in the Everest region. The Everest Base Camp trek and the expedition of Mount Everest opened the gate of tourism in the area. Since then, the Gokyo region has seen a gradual rise in the number of trekkers arriving there.

Trekkers get blessed with the scenic, tranquil beauty of the region. While not as mainstream as the EBC trek, the Gokyo Lake trek is also on the list of avid trekkers. This trek is especially ideal for those trekkers who have already trekked at the Everest Base Camp. These treks can also get included in the EBC trek itinerary.

There is a small settlement at Gokyo village at 4,790 m (15,720 ft), the center of the area. Trekkers can arrive at this village after walking uphill from Namche Bazaar for two days. The trekking concludes after arriving at the the Gokyo Ri summit, the region’s maximum point.

Impacts of Tourism on the Gokyo Lakes

Gokyo Lakes

The Gokyo Valley is gaining popularity among tourists and trekkers in the Everest region. However, tourism has impacted the natural, cultural environment of the area. There are tremendous positive impacts, including local employment generation.

However, the mountain ecosystem of the Gokyo region is quite fragile. Therefore the increase in the number of people traveling is degrading the green pastures of the Gokyo Valley into scrubland. There is deforestation and overgrazing which contribute to this aspect as well.

Human waste is another problem in the region as the need for luxury facilities has increased with tourists. The yak herders and farmers have abandoned their ancient occupations and turned to the hospitality business.

An increase in tourism has also led to higher firewood demands which have seen the massive use of local resources for heating. This is quite impactful as the vegetation takes more time to grow in higher altitudes. Ngozumpa is a melting glacier due to global warming. There are adverse effects of climate change throughout the region.

Hence, the Gokyo lakes are expanding, whereas the Ngozumpa Glacier is shrinking. According to an ecological study, the Himalayan ice will melt completely over 30 years. Therefore, these are the various impacts of tourism in the Gokyo region.

Wildlife Around the Gokyo Region

The conservation area status of the region means that the rare and endangered flora and fauna remain protected. The subalpine forests include fir, juniper, birch, and rhododendron trees. These florae get found at 4,000-5,000 m (13,000-16,000 ft).

You can find mosses and lichens above 5,000 m (16,000 ft). There are at least 1,000 floral species, with 208 bird species in the national park. The birds found in the region include the Impeyan pheasant, snowcock, bearded vulture, etc.

Himalayan tahr, snow leopard, serow, and musk deer are generally above 3,500 m (11,500 ft). There are other wild animals in the lower regions as well. The fantastic variety of birds makes their bi-annual trans-Himalayan migrations in the lakes area. Mainly migratory ducks and wood snipes fly from the Tibetan region.

Moreover, there are numerous medicinal and aromatic plant species. The species of plants include Kobresia fissiglumis, which are valuable medicinal plants. Overall, the Gokyo Lakes region is rich in flora and fauna.
