Mandakini River

[2] The Mandakini merges with river Songanga at Sonprayag and flows past the Hindu temple Madhyamaheshwar at Ukhimath.

[1] The Mandakini is considered by Hindus a sacred river within Uttarakhand as it runs past the Kedarnath and Madhyamaheshwar temples.

[5] The Mandakini area also attracts millions of tourists annually for whitewater rafting, hiking, and religious tours around the winter Chardham being offered.

[1][3][6] The health of the river and surrounding landforms have slowly been degraded, giving rise to environmental conservation projects such as the Kedarnath Wildlife Sanctuary.

[2] In conjunction with the collapse of a segment of the dammed Chorabari Lake in 2013, an intense patch of heavy rainfall led to the historical devastation of rural villages and death of thousands of locals, pilgrims and tourists.

[12] The region houses very steep valleys and large slopes, which commonly result in great sediment movement and landslides.

[12][13] With a total length of approximately 80 km (50 mi) between regions Kedarnath and Rudraprayag, the Mandakini stretches past many significant locations of Uttarakhand.

[14] In recent years (from data received between 1962 and 2014), however, exposure to higher temperatures and increased human intervention has seen a reduction in landmass of the Chorabari glacier (a loss of 1% of its frontal area and approximately 344 m [1,129 ft] of its length).

These extend to the shrine of Tungnath and retrace the footsteps of important Hindu sages such as Swami Rama and Bengali Baba.

[17][1] Many of these harvested plants are also used as natural medicines and aphrodisiacs, making Chitrakoot a hub for crop trade in the Mandakini area.

[16] On June 16–17, 2013, unprecedented rainfall and damage to dammed areas of the Chorabari glacier caused the Mandakini and its tributaries in the Garwhal Himalaya to flood and subsequently devastate surrounding villages.

were the most heavily impacted due to an accumulated debris buildup from damaged villages upstream, creating a 'snowball effect' of devastation.

While numerous homes and farms were destroyed in the floods, the majority of shrines and the Kedarnath temple were left intact.

Some methods include conservation plans, wildlife sanctuaries and the strategic placement of concrete blocks to restore the original and favoured course of the river.

[citation needed] A general increase in temperatures, which scientists from the Department of Water Resources Development and Management, Indian Institute of Technology, Roorkee, India, attribute to climate change, has been recorded in the area.

Increased levels of rainfall have also been attributed to climate change, with researchers predicting larger numbers of soil loss occurring over coming years.

[citation needed] The Mandakini has become a prime location for investigating the impact of waste dumping and tourism on the quality of water.

[3] Due to its cultural and religious significance, the Mandakini and neighbouring villages attract thousands of tourists and pilgrims each year.

The following activities were observed by these same researchers during sampling of the Mandakini at various locations; religious, tourism, bathing, washing, open defecation, cultivation, sand, stone and gravel recovery, stone crushing, road construction, mining, cremation; fishing, surface drainage, irrigation, drinking water, rafting, and interacting with wildlife habitats.

The towns of Chitrakoot, Rambara and Kedarnath have also been known to cover river banks in concrete for the construction of fisheries and docks.
