This rarely gets reported in media, but IMD (India Meteorological Department) also provides river basin wise rainfall figures. Here is an overview of the river basin wise rainfall during SW Monsoon 2020 (June-Sept 2020, though the monsoon withdrew much later), like the way we have been doing for the last three years[i].

W Ghats Forests vital for Tamil Nadu SW Monsoon Rains Researchers have found that the dense vegetation in the Western Ghats determines the amount of rainfall that Tamil Nadu gets during the summer monsoon. A team led by Prof. Subimal Ghosh from the Department of Civil Engineering at the Indian Institute of Technology (IIT) Bombay has found that dense forests of the Western Ghats contribute as much as 40% of moisture to the southwest monsoon rainfall over Tamil Nadu during normal monsoon years. The average contribution is 25-30%. But during monsoon deficit years, the contribution increases to as high as 50%.
