Details
The Beas River originates in the Himalayas and flows southwestward through the scenic Himachal Pradesh landscape before entering Punjab. The river valley is renowned for natural beauty and temperate forests. Historically, the Beas marks significant boundaries in Indian mythology and history; the ancient Greek general Alexander the Great stopped his eastward invasion at the Hyphasis (Beas) River around 326 BCE. The river valley sustains agriculture and human settlements dependent on its water. Multiple hydroelectric projects including the Pong Dam harness the Beas's energy potential, generating clean electricity for the region. The Pong Wetland, created by the dam's reservoir, is a Ramsar wetland site supporting migratory birds and aquatic ecosystems. The river's ecology supports diverse fish populations and riparian vegetation adapted to monsoon patterns. Water-sharing agreements between Himachal Pradesh and Punjab govern the river's utilization, balancing hydropower generation with downstream irrigation needs and environmental flow requirements.
