The Salaulim Dam (also spelled Selaulim, Saluli) located on the Salaulim River, a tributary of the Zuari River in Goa, India, is an integral component of the Salaulim Irrigation Project which envisages benefits of irrigation and drinking water supply. The dam is a composite earth-cum-masonry dam of 42.7 metres (140 ft) height with a water spread area of 24 km2 (9.3 sq mi). It was initially planned to provide irrigation to an ultimate potential of 14,326 hectares (35,400 acres) and water supply of 160 million litres per day (MLD) to South Goa; the water supply component for domestic and industrial use is now increased to 380 MLD. The initial cost of the project when approved in 1971 was Rs. 9.61 crore, which, as of 2007, is estimated to cost Rs 170 crores. Construction of the project was however started in 1976, the dam was completed in 2000 and the irrigation component is under final stages of completion having achieved an irrigation potential of 9,537 ha, as of 2007.
The project is located at Sirga about 5 km from the Sanguem town, in the Zuari River Basin, which is drained by the Zuari River which in turn is formed after the confluence of Selaulim (also spelled Salaulim) and Uguem Rivers in Sanguem taluk. The Salauilm dam is located on the Selaulim River (also known as Sanguem) near the Sanguem town. The river drains a catchment area of 227 km2 (88 sq mi).
The dam is a composite structure of earth-cum-masonry type of 42.70 metres (140.1 ft) height above the deepest foundation level. The length of dam at the crest is 1,004 metres (3,294 ft) and the reservoir water spread area (within Goa without inter-state implications) is 24 km2 (9.3 sq mi). The dam structure has a volume content of 2.714 million cubic metres (MCM). The gross storage capacity of the reservoir is 234.361 MCM with the live or effective storage capacity fixed at 227.157 MCM. The spillway which is of the unique Duckbill type (Morning Glory type) is an ungated structure located in the gorge section with a length of 44 metres (144 ft) which is designed to pass an estimated Design Flood Discharge of 1,450 cubic metres (51,000 cu ft)/s. Out the total live storage of about 227 MCM, 126 MCM is for irrigation and the balance 101 MCM is earmarked for domestic and industrial water use. As a result, 220 MLD of water is available for industrial and domestic use in South Goa, in addition to 160 MLD originally provided in the approved project.
