As of late June 2025, Goa’s reservoir levels show a mixed picture—highlighting both the benefits of an early monsoon and the strains of infrastructure work and uneven rainfall.
In South Goa, the Selaulim dam— the region’s main drinking water source—hit full capacity and began overflowing on June 25, a full twelve days earlier than usual. This marks the earliest spillover in 25 years, credited to strong pre-monsoon storage and a vigorous start to the monsoon season, ensuring robust water security for the southern region.
However, the situation is more concerning in North Goa, where the Amthane and Anjunem dams are at critically low levels, holding only 11% and 23% of their respective capacities. Inflow to the Amthane dam has been deliberately restricted to allow for gate replacement and repairs, following earlier issues where jammed gates disrupted supply during maintenance at the Tillari project. Meanwhile, Anjunem’s low level is the result of weak rainfall in its catchment area, though officials are hopeful the situation will improve as the monsoon progresses.
Other reservoirs are performing better: the Chapoli dam in Canacona stands at 71%, Panchwadi at 88%, and the Gaunem reservoir has reached full capacity and is overflowing, offering relief to surrounding communities. The Tillari reservoir, which caters to both North Goa and parts of Maharashtra, is currently at 60%, supporting drinking water and irrigation needs.
While North Goa faces temporary shortages and maintenance-related constraints, the overall water situation across the state remains stable. Authorities are monitoring the conditions closely, expressing confidence that the ongoing monsoon will help recharge the underperforming reservoirs and ensure consistent supply throughout Goa.
