From mid-2009, Gogoi had led a statewide movement against construction of big dams in the ecologically sensitive regions of Assam and Arunachal Pradesh. His organisation KMSS demanded immediate halt to the ongoing construction of the dam of Lower Subansiri, a mega hydroelectric power project under NHPC with an estimated capacity of 2000 MW. In December 2011, huge number of anti-big dam protestors led by Gogoi stopped trucks transporting parts of turbines to the Lower Subansiri Hydro-electric Power Project site in Gerukamukh, Lakhimpur district, thereby significantly slowing down the process of construction of the dam for the next many years. The dam is still not complete. In 2014 Gogoi initiated a campaign against land mafia in Assam, who had appropriated thousand of acres of agricultural land in rural Kamrup district, adjoining Guwahati city, from poor farmers. The matter is currently under investigation.
