Song Da Reservoir
Location:
20°48'N, 105°19'E; near the town of Hon Binh, ha Son Binh Province.
Area:
72,800 ha.
Altitude
c.100m.
Biogeographical Province:
4.10.4.
Wetland type:
17.
Description of site:
A large water storage reservoir with a capacity of 1.6 billion cubic metres, constructed in 1985 on the Da River for the generation of hydro-electric power, irrigation, aquacuiture and water regulation. The reservoir is surrounded by secondary forests, cultivated areas and human settlements.
Climatic conditions:
Tropical monsoonal climate.
Principal vegetation:
No information is available on the aquatic vegetation. The natural vegetation in surrounding areas includes young secondary forest, bamboo, shrubs and grasses, especially Imperata cylindrica, Melastoma candidum, Rhodomyrtus tomentosa and Cratocylon sp.
Land tenure:
Owned by the People's Committee of ha Son Binh Province.
Conservation measures taken:
The water catchment area of the reservoir is protected. Some reafforestation is being undertaken around the reservoir, and agro-forestry schemes are in operation in the area.
Conservation measures proposed:
 
Land use:
Generation of hydro-electricity, water supply for irrigation, fishing and recreation.
Possible changes in land use:
 
Disturbances and threats: The main threat is cultivation on steep slopes in the catchment area, which leads to serious erosion and consequent siltation problems.
Economic and social values: The reservoir is very important for the local and national economy because of its hydro-electric power (1.92 million kw). It irrigates a huge area in the Da River basin, and should eventually support a major fishery of considerable importance to the local communities. The reservoir has considerable potential for recreation and tourism, which could provide a good income for local people.
Fauna: The reservoir is still very young and is of little value for wildlife. However, as the lake matures and if the adjacent secondary forests are protected, the area could become important for a variety of wildlife species, including waterfowl.
Special floral values: None known.
Research and facilities:  
Criteria for inclusion: 1e.
