Singhal was re-elected to Assam Legislative Assembly in 2021 from Dhekiajuli with 93,768 votes defeating Benudhar Nath of Congress party.

[citation needed] The movement to save the Brahmaputra reached its peak when in the year 2010, Jana Jagriti claimed that China was not only diverting water from the Brahmaputra (called Yarlung Zangto in China) at Great Band by constructing a tunnel but also undertaking a series of infrastructure development projects along the Tibetan plateau.

Few believed him when he first highlighted a series of Chinese hydro-power projects on the Yarlung Tsangpo (also called Yarlung Zangbo in China and Brahmaputra in India), through satellite imageries and warned people and the governments in the northeastern states of the danger of the mighty river slowly getting dried up.

Later, he was vindicated when Beijing officially intimated New Delhi on blocking a Tsangpo tributary in September, 2016.

The NGO believed that once those projects get commissioned, the flow of Tsangpo water into India will be reduced by 64% during monsoon and 85% during the non-monsoon months.

According to Jana Jagriti, India receives 78.10 BCM water from China through Brahmaputra at its entry point at Gorging village in Arunachal.
