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.
Run-of-river hydroelectricity (ROR) or run-of-the-river hydroelectricity is a type of hydroelectric generation plant whereby little or no water storage is provided. Run-of-the-river power plants may have no water storage at all or a limited amount of storage, in which case the storage reservoir is referred to as pondage. A plant without pondage is subject to seasonal river flows, thus the plant will operate as an intermittent energy source. Conventional hydro uses reservoirs, which regulate water for flood control, dispatchable electrical power, and the provision of fresh water for agriculture.
Umiam Lake is a reservoir in the hills 15 km (9.3 mi) north of Shillong in the state of Meghalaya, India. It was created by damming the Umiam River in the early 1960s. The principal catchment area of the lake and dam is spread over 225 square km.
