Goa Selaulim Reservoir Fills Ahead of Time This Monsoon
The Selaulim Dam in South Goa reached full capacity on Wednesday—nearly two weeks ahead of schedule following a strong early onset of the southwest monsoon. The early overflow marks a significant boost for irrigation, drinking water supply, and groundwater recharge, reinforcing hopes for a steady water reserve through the season in the region. This is a welcome sign for Goa’s water security.
The southwest monsoon arrived early in Goa on May 25 this year, bringing consistent rainfall across South Goa’s catchment areas. As a result, the Selaulim reservoir, the largest in the region, hit full capacity by June 25. Experts from the Water Resources Department noted this is one of the earliest recorded overflows in recent years. Smaller reservoirs like Gaunem in Canacona had already reached capacity days earlier, pointing to widespread hydrological benefit.
Selaulim Dam plays a pivotal role in the region’s water management, supplying raw water for treatment across South Goa. Located in Ugem, Sanguem, the dam features a distinctive duckbill spillway designed to automatically release surplus water. This spillway can handle a peak discharge of up to 1,450 cubic metres per second, ensuring that excess rainfall is diverted downstream to recharge the Selaulim river and support rural irrigation networks.
Beyond its utility, the dam has also become a seasonal attraction during monsoon. The dramatic sight of water cascading over the spillway draws both residents and tourists to the area. The scenic overflow is particularly striking amid Goa’s lush monsoon landscape. However, authorities have urged visitors to exercise caution, as wet conditions around the structure can be hazardous. Safety measures have been put in place to prevent accidents near the spillway.
Officials believe the early filling of reservoirs could ease stress on agricultural and drinking water systems through the season. With monsoon rains continuing across the state, expectations are high for similar overflows in other major dams. While the event brings cheer to locals, authorities are also closely monitoring the downstream flow to manage water distribution and avoid flooding in low-lying regions.
The early overflow of the Selaulim Dam underscores the positive impact of Goa’s advancing monsoon. While it ensures an ample water supply for South Goa, it also enhances agricultural prospects and ecological replenishment. Authorities are balancing celebration with caution, reminding visitors of safety near the spillway. As rains continue, the region is better positioned to face the season with robust water infrastructure already in action.
