Diamer Bhasha Dam Need Of Pakistan

The dam site is situated near a place called "Bhasha" in Gilgit-Baltistan's Diamer District, hence the name.

The dam site is situated near a place called “Bhasha” in Gilgit-Baltistan’s Diamer District, hence the name. The project is located on Indus River, about 315 km upstream of Tarbela Dam, 165 km downstream of the Northern Area capital Gilgit and 40 km downstream of Chilas. The proposed dam would have a maximum height of 270 m, and imvpound a reservoir of about 7,500,000 acre feet (9.25×109 m3), with live storage of more than 6,400,000 acre feet (7.89×109 m3). Mean annual discharge of Indus River at the site is 50,000,000 acre feet (6.2×1010 m3). Thus the dam will impound 15% of the annual river flow. The dam project would cover an area of 110 km2 and extend 100 km upstream of the damsite up to Raikot Bridge on Karakoram Highway (KKH).MAIN DAM

On April 4, 2008, it was reported in several major South Asian newspapers that Buddhist artifacts, possibly numbering in the thousands, have been recovered at the site of the Diamer-Basha Dam. According to these articles, the beleaguered engineering firm Lahmeyer International, which has been involved in planning out the dam, has suggested a museum be built to house the artifacts. Also, an unnamed German scholar affiliated with a German archaeological university (possibly the German Archaeological Institute) has traveled to Pakistan to study the artifacts. The Government of Pakistan has now decided to secure and relocate all items of archaeological significance from the areas that will be inundated by the Diamer-Bhasha Dam and its reservoir and to place them in a newly constructed museum near the Dam site.

After Reducing Dam Height by 10m

No. of villages affected 30

No. of Houses Affected 2200

Population affected 22,000

Agricultural land submerged 1,500 acres (6.1 km2)

Area under reservoir 25,000 acres (100 km2)

Length of KKH submerged 100 km

Proposed new settlements 9

Infrastructure Electricity, roads, water supply, schools, health centers etc.

Agriculture is the backbone of Pakistan’s economy. Pakistan today is among one of the World’s fastest growing population, now estimated as over 150 million. Due to lack of large river regulation capability through sizeable storages, the country is already facing serious shortages in food grains. Given the present trend, Pakistan could soon become one of the food deficit countries in the near future. Therefore, there is a dire need to build storages for augmenting agriculture production. Tarbela, Mangla and Chashma reservoirs have already lost about 5,000,000 acre feet (6.2×109 m3) due to sedimentation. It is estimated that by year 2012, this loss would increase to 6,000,000 acre feet (7.4×109 m3), almost equal to the original combined capacity of Mangla and Chashma reservoirs. Due to complete stoppage of any sizable multi-purpose storage development after commissioning of Tarbela Dam in 1976, sustainability of existing irrigated agriculture of Pakistan is in serious jeopardy. The President has taken a very bold initiative by taking the decision to construct Diamer Basha Dam Project.
