Data | An unusually wet October fills up reservoirs in Kerala
The Hindu
In 10 of the 14 districts, rainfall received in October was twice the Long Period Average
In the first 20 days of October 2021, every district in Kerala received more than 250mm of rainfall. In 10 of the 14 districts, rainfall received in October was twice the Long Period Average (LPA). As rainfall increased, water inflow to reservoirs also increased in October, swelling their storage to very high levels. Heavy to very heavy rainfall (64.5mm to 204.4mm) is predicted for Pathanamthitta, Kottayam and Idukki districts on Thursday. Therefore, inflows into major reservoirs in these districts and the resulting spills (excess water deliberately released from reservoirs) have to be closely monitored.
The graph shows the actual rainfall received in the first 20 days of October 2021 and the % departure from the LPA in every district of Kerala.
