Krishna Janmasthami is an annual commemoration of the birth of the Hindu deity Krishna, the eighth avatar of Vishnu. The festival is celebrated on the eighth day (Asthami) of the Krishna Paksha (dark fortnight) of the month of Bhadra (August–September). In this year the festival is on 28th August and also celebrates in Dolakha town.

Glacial hazards in the Rolwaling valley of Nepal and numerical approach to predict potential outburst flood from glacial lake
In recent years, climate change and retreating glaciers constitute a major hazard in the Himalaya of South Asia. Glacial lakes are rapidly developing or increasing due to climate change. The rapid development of the lake may cause outburst of the lake. The outburst discharge from the glacial lake can cause catastrophic flooding and disaster in downstream area. Therefore, it is necessary to investigate the impact of climate change on glacial lakes and to understand the characteristics of the glacial lake outburst. In this study, the field assessment of Tsho Rolpa Glacial Lake in the Himalaya of Nepal has been presented and the impact of climate change on this glacial lake has been discussed. The Tsho Rolpa Glacial Lake is the largest and most potentially dangerous glacial lake in Nepal. In addition, a numerical model has been also developed for computing the characteristics of glacial lake outburst due to moraine dam failure by seepage and water overtopping. The numerical model is tested for the flume experimental cases. The simulated results of the outburst discharge, the dam surface erosion, and the temporal variation of the moisture movement in the dam are compared with those obtained from the hydraulic model experiments. The moisture profile calculated by numerical model was agreeable with the experimental moisture profile. The simulated failure surface of the dam due to seepage by considering the suction in slope stability analysis gave more agreeable results than the Janbu's simplified method. The results of the outburst discharge and dam surface erosion also agreed with the experimental results.

Dolakha bazar is very rich in culture and festivals, of course natural also. Bhairab Kumari Jatra is also one of the major religious celebrations in Dolakha. Every year Bhairab-Kumari Jatra starts on the next day of the Gaijatra. The festival consists of masked dances that go on non-stop for five days every year, which has started from August 23rd in this year and finished yesterday night. Thirty-two persons dressed in costumes, including that of 'Bhairab' and 'Kumari', move around the market and temples with dancing in martial style. Dolakha bazaar was busy with devotees arriving from different parts of the country to observe the Jatra. On the occasion, devotees also undergo fasting and worship Bhairab and Kumari. The festival started about 500 years ago and has great religious significance.

Glacial lake outbursts are a major hazard in the South Asian Himalaya and other glacier regions of the world. Climate change and glacier retreat have heightened the danger of outburst events, as new glacial lakes have formed and expanded. The outburst discharge from glacial lakes may cause catastrophic flooding and damage in downstream areas. It is thus important to investigate the impact of climate change on glacial lakes and to understand lake behavior. This study examined glacier- and sediment-related hazards in the Rolwaling Valley of Nepal, and field-assessed the Tsho Rolpa glacial lake in the valley. Potential causes of moraine dam failure at Tsho Rolpa include overflow and erosion of the dam caused by ice or boulders falling into the lake, seepage inside the dam, melting of the ice core inside the dam, or an earthquake. The peak outburst discharge from Tsho Rolpa was estimated to range from 7,759 to 90,296 m3/s using different empirical equations. The resulting flood would cause serious damage up to 100 km or more downstream, threatening many people, agricultural lands, forests, hydroelectric projects, and other infrastructure.

GaiJatra (Cows Festival) in Dolakha
Gaijatra, the festival of cows, is also celebrated in Dolakha Bazar (this year on August 22nd). The Gaijatra festival of Dolakha is very unique and special than that in Kathmandu valley. This festival is mainly celebrated by Newari people. The festival commemorates the death of people during the year. Also we can see some Gaijatra comedies/caricatures in the festival.

Lakhe Jatra begins in Dolakha after the Gathamangal Jatra. This Lakhe Jatra is going to continue until Janai Purnima (this year August 21st ). This festival mainly is celebrated by Newari caste only. On the day of Janau Purnima, Dolakhali newari people celebrate it with Dwaki Dakas ‘Big Lakhe’. The Lakhe dance of this day is very important to all Dolakhali people and also many people from other parts of the Dolakha district visit Dolakha town to see this Big Lakhe dance.

Building-one has one office room and two class rooms.
Building-two has four classrooms.
The construction of the Simigaun school buildings shown in the photographs was supported by Roman mueller and his friends, Germany. Still some help for maintenance of buildings is necessary.
