The early arrival of the southwest monsoon has brought a surge in rainfall across Goa, significantly lifting water levels in key reservoirs and raising hopes for improved water security this season. According to the Water Resources Department, multiple dams across the state, including the crucial Selaulim reservoir, have recorded sharp gains in storage over the past few weeks.
The Selaulim dam, which supplies drinking water to South Goa regions such as Margao, Vasco, Quepem, and Sanguem, has risen from 37% of its capacity in mid-May to 54% as of mid-June. This is encouraging for the water security of South Goa,” noted an official from the department. In the southern taluka of Canacona, the Chapoli dam has reached 55% capacity. Gaunem dam, serving Ponda taluka, now stands at 78%.
However, the situation in northern and interior regions remains mixed. The Anjunem dam, a key water source for the Sattari region and sections of Bicholim, has seen levels fall from 21% in May to a concerning 10%. The Amthane dam, which supplies Bardez, Pernem, and surrounding areas, has also recorded a decline—from 49% to 31%. “These variations are not unusual during the early monsoon,” the Water Resources Department official explained.
With the India Meteorological Department (IMD) predicting a vigorous and widespread monsoon in the coming weeks, we expect lagging reservoirs to catch up.’’ The Tillari reservoir, which provides water to parts of north Goa and neighbouring Maharashtra, has maintained stable levels at 25% since May. Though not yet rising, officials are optimistic that this vital inter-state source will show an uptick as monsoon intensifies.
Experts point out that dam replenishment during the early phase of the monsoon is critical to ensure uninterrupted drinking water and irrigation supply during the post-monsoon season. With climate variability affecting rainfall patterns, timely storage in reservoirs offers a buffer against dry spells and delayed rainfall events later in the year.
With forecasts favouring a strong monsoon and the early surge in rainfall already yielding positive results, the water outlook for Goa appears promising. Continued monitoring and adaptive reservoir management will be key in translating this rainfall bounty into long-term water security for households, farmers, and industries alike.
