The Lower Se San/Sre Pok 2 scheme is a proposed hydroelectric dam to be located in Stung Treng Province, Cambodia on the Tonle Sre Pok some 2 kilometres (1.2 mi) upstream of its confluence with the Se San, and about 37 kilometres (23 mi) upstream of the confluence of the combined Sre Pok, Se San and Se Kong rivers with the Mekong mainstream.

Prefeasibility Study, the project aims to construct and operate an installed capacity 222 megawatts (298,000 hp) low head hydroelectric generating facility on the Sre Pok River, generating annually 1,060 GWh (3,800 TJ), run-of-river dam, reservoir 120 square kilometres (46 sq mi) Main components include construction of a concrete gravity dam, the powerhouse and generating equipment, environmental and social mitigation measures, and the 220-kV transmission line to Stung Treng and onwards to the Vietnamese border to interconnect with the Vietnamese grid backbone.

The scheme has a much smaller reservoir area (120 square kilometres (46 sq mi)) than the Lower Se San 2 site (355 square kilometres (137 sq mi)) and consequently a lesser environmental impact. The number of inhabitants in the reservoir area for resettlement is also significantly less. The dam is low in height, but could still have a significant impact on navigation and fish migration, which is a particular concern at all sites in this area. Allowances have been made in the scheme design and cost estimate for mitigation of these impacts, so far as is possible.

Per MIME report to RPTCC-4 meeting (Yangon, Sept. 2005), commissioning of 222 MW Lower Sre Pok HPP will be in 2017.

Impact: Up to 1000 people may rewire resettlement.[4]
