History
The reservoir was created by constructing Afobaka Dam across the Suriname River between 1961 and 1964. The dam spanning the river is 54 m (177 ft) tall, and is built near the small town of Afobaka. Contrary to the reservoir's long official name, it was quickly rechristened Brokopondomeer by Dutch-speaking locals, after the town of Brokopondo 3 km (2 mi) further downstream from where the dam was constructed. The length of the dam, including secondary dams along the margins of the reservoir, is 12 km (7+1⁄2 mi). The watershed which feeds the reservoir is 12,200 km2 (4,700 sq mi) in area.[2]
The reservoir was put into service in 1965, but did not reach its optimal water level until 1971. Due to the great area of the reservoir, villages home to approximately 5,000 people had to be abandoned. The largest of these, the village of Ganzee, had approximately 1,200 residents.[3] Most displaced residents were moved to new villages (Dutch: transmigratiedorpen) downstream from the dam, in many cases with the same names as the previously abandoned hamlets. The most important being Klaaskreek, Nieuw Ganzee,[3] and Marshallkreek.[4] A separate government operation, "Operation Gwamba," was conducted to save animals from the soon-to-be lake bed.
The dam was constructed in order to provide electricity to plants involved in the processing of
Criticism
According to the 2003 World Bank report Good Dams, Bad Dams, the Brokopondo dam (Afobaka Dam) flooded significantly more hectares of land per megawatt generated than any other large hydropower project analyzed.[5] The report notes that Brokopondo inundated roughly 160,000 hectares of biologically valuable tropical rainforest, while providing only 180 megawatts of capacity, equivalent to 889 ha/MW. For comparison the controversial Three Gorges Dam in China flooded 6 hectares per megawatt, providing 18,000 megawatts while flooding an area smaller than Brokopondo. The global average for all large hydroelectric dams constructed to date is about 60 ha/MW, according to the same report.[6]
Harvesting of trees
As a cost reducing measure, the trees of the area were not cut before they started to submerge. This caused problems for shipping activity in the lake. In 2002, Brokopondo Watra Wood International N.V. (BWWI) was given permission by Suralco to a start a pilot investigating the possibility to harvest the remaining trees from the lake. The idea came from the late Paramaribo entrepreneur Orlando Lee On, who read about similar harvesting efforts in the Tucuruí Lake in Brazil when on a plane to Miami.[7][8] In 2004 harvesting began, which resulted in the first shipment of wood from the lake to Europe and the United States in June 2005.[9] The Brokopondo lake wood is marketed in Germany as "Stauseeholz" (English: Reservoir wood).[10] In November 2010, Jens Hahne filmed a documentary about the harvesting activities for the Franco-German channel Arte.[11] This documentary was broadcast on Arte on 22 January 2011.[12]
