Monitoring groundwater in wells, together with rainfall measurements and streamflow can answer whether heavy pumping in the plains may be lowering down the water table below streambed level. However, that usually requires instrumentation which may not be available. Replacing the native vegetation by fast growing exotic trees ( eucalyptus specius, albizzia etc) can lead to high rates o water uptake, and indeed have been seen to lower groundwater and dry up springs in the Nilgiris. I assume you are referring to the Palnis, near Palani and Pollachi ?
