Salal Dam, also known as Salal Hydroelectric Power Station, is a run-of-the-river hydropower project on the Chenab River in the Reasi district of the Jammu and Kashmir. It was the first hydropower project built by India in Jammu and Kashmir under the Indus Water Treaty regime. After having reached a bilateral agreement with Pakistan in 1978, with significant concessions made to Pakistan in the design of the dam, reducing its height, eliminating operating pool, and plugging the under-sluices meant for sediment management, India completed the project in 1987. The concessions made in the interest of bilateralism damaged the long-term sustainability of the dam, which silted up in five years. It currently runs at 57% capacity factor. Its long-term future is uncertain.
