The task of conceptualising social movements draws on a wealth of watery images, from protest waves and political currents, to imagining mobilisations as tides, ripples, cascades or high‐pressure hydraulics. Called upon to analyse complex processes, these waters have a life of their own, carrying analytical implications while extending a relationship to water that is never only symbolic and is material, embodied and historical. This article explores the ways water is “enrolled” to understand movements, to advance three arguments: first, these use familiar water morphologies to naturalise particular, located understandings of political change and social form; second, they imply normative claims and ideological affinities regarding political struggle; third, this has implications for our relationship to water, echoing the abstract and alienating “modern water” of capitalist world‐ecology. The article considers how critical water knowledges and subjectivities, often sustained by social movement spaces, indicate possibilities of a being‐otherwise with water and its meanings.
