The National Mission for Clean Ganga (NMCG) has released a draft Small River Rejuvenation (SRR) Framework aimed at restoring India's smaller rivers. Significantly, the framework deliberately separates small-river conservation from the large-river model used for the Ganga basin, and leans instead on local, nature-based measures, scientific assessment and community participation.

At its core, the SRR Framework is a policy draft tailored for small river systems. It proposes a shift away from big engineering interventions towards river-specific planning built on hydrology, ecology, land use and local water availability. The word "rejuvenation" here means restoring the flow, water quality and ecological functions of these smaller waterways rather than merely building structures around them.

The planning toolkit is detailed: hydrological and hydrogeological studies, ecological assessment, water-quality analysis and GIS mapping, followed by preparation of a Detailed Project Report. Operational activities include source conservation, abatement of liquid and solid pollution, ecological restoration, channel improvement and public-river connection efforts. For rural small rivers the priority is natural connectivity and local water storage; for urban small rivers the focus shifts to continuous flow and management of urban runoff.

NMCG has linked the framework to the twin principles of Nirmal Ganga (cleanliness) and Aviral Ganga (uninterrupted flow), while stressing that smaller rivers need distinct methods because their catchments, discharge patterns and pollution sources differ from major systems. Crucially, it assigns maintenance and protection responsibility to riverbank communities — placing stewardship within local participation rather than awareness drives alone. On funding, the framework avoids costly standalone infrastructure and instead proposes convergence of money from existing Central and State schemes.

For aspirants, this connects environment, governance and river-management themes and is directly relevant to UPSC, RPSC, SSC and State exams.
