The Asian Development Bank through its contractor, the Snowy Mountain Engineering.Corporation were tasked with exploring the potential of augmenting the capacity of the Afulilo Reservoir to power a third turbine at the Ta’elafaga Hydro-power Station. To assist in this augmentation assessment, SMEC arranged with the Secretariat of the Pacific Regional Environment Program to oversight a consortium of partners to conduct a 11 month monitoring program with the purpose of assessing the status of the marine environment, particularly the coral reefs, as well as water quality in the Fagaloa and Uafato Bays. The data from the 2009-1010 marine monitoring program implies that several sites in Fagaloa Bay are exhibiting signs of various impacts from various inputs into the marine environment, which are most notable at sites 1, 2, and 14. These sites are closest to the apex of Fagaloa Bay where the Ta’elefaga Creek discharges into. Impacts for these sites include low or no coral cover and recruitment, growth in algal cover, lower salinity levels, higher rates of sedimentation and turbidity, as well as high nutrient inputs. Fish biomass at site 14 was also the lowest (sites 1 and 2 were not surveyed due to poor visibility). Other specific results across all sites include a reduction in live coral cover, a general shift to more hardier coral species, and low fish bio-mass when compared with other sites in Samoa.
