Rawal Dam Spillways Open as Reservoir Nears Capacity Amid Monsoon Rains
Authorities opened the spillways of Rawal Dam in Islamabad early Monday after the reservoir's water level climbed close to its maximum capacity amid continuing monsoon rainfall in the federal capital and surrounding areas. The controlled release began at around 6am as officials moved to create additional storage space for further inflows expected from rainfall in the coming days.
The reservoir's water level had risen to 1,751.40 feet, just below its maximum storage level of 1,752 feet. Officials said releasing water through the spillways was necessary to keep the reservoir at a safe level and provide room for additional water entering the dam during the ongoing wet spell. The latest opening marks the third time this year that Rawal Dam has approached levels requiring discharge through its spillways.
The release has increased attention on Korang Nullah, which receives water flowing downstream from the reservoir. Authorities have warned that the discharge could result in stronger currents in the nullah and have advised people living nearby to remain alert. Residents have specifically been urged not to cross the watercourse or use temporary bridges when water levels and flow speeds are elevated.
The National Disaster Management Authority issued precautionary guidance for communities adjoining Korang Nullah, asking residents to closely monitor changing water conditions. The authority stressed that people should avoid unnecessary movement near the nullah during periods of increased discharge and should not attempt to cross temporary structures over fast-moving water.
The spillway opening comes as monsoon rains continue to affect Islamabad and nearby areas, placing additional pressure on reservoirs and natural drainage channels. With Rawal Dam already close to its maximum storage level, authorities are attempting to balance current water levels against the possibility of fresh inflows from additional rainfall. Controlled releases are intended to preserve storage capacity while reducing the risk associated with the reservoir remaining near its upper limit.
For residents downstream, the immediate impact is the possibility of rapidly changing conditions along Korang Nullah as discharged water moves away from the dam. Officials' warnings are focused on preventing accidents involving pedestrians, motorists and people using temporary crossings. The advisory is particularly important where water levels can rise quickly following rainfall or increased releases from the reservoir.
Authorities are expected to continue monitoring Rawal Dam's water level, incoming flows and weather conditions before deciding whether discharge levels need to be adjusted. Residents in nearby and downstream areas have been asked to remain cautious and follow official safety instructions while the monsoon system continues to influence water levels in and around Islamabad.
