•Number of monitoring stations will be increased to 2500 during 11th Plan.•The optimum network to cover all the surface water bodies would be about 10000 monitoring stations.•Monitoring of micro pollutants will be strengthened with quality assurance.•Optimization of monitoring locations, parameters and frequency of monitoring.
