In the locales where hydropower dams in the Mekong River Basin have been constructed, ethnically and economically marginalized groups who depend on rivers and their tributaries for well-being often bear the greatest burdens: loss of fisheries and river-based livelihoods, riverbank gardens, and sacred sites, to name a few. In December 2018, the controversial Lower Sesan 2 Dam in northeastern Cambodia started operations, exacerbating old challenges and creating new ones for the riverine communities along the Sesan and Srepok Rivers. In this article, I employ a feminist political ecology framework to explore the varying ways that personal and community well-being are impacted in two ethnic Lao locales of Sre Kor (Na Kor in Lao language) commune and Phluk village as a result of the Lower Sesan 2 Dam. While the dam has disrupted flows of water and fish habitats and migrations, rendering new ecological circumstances, I argue that infrastructural violence can variably hide intimate geographies of well-being and un-wellness. Only by interrogating the silences of intimate geographies of the body and home in local villages and communal ethnic spaces will such impacts of violence become visible.
