How is the siltation situation of Feitsui Reservoir?

Since the initial impoundment of Feitsui Reservoir in July, 1984, Feitsui Reservoir has actively worked with other authorities to promote the catchment's area soil and water conservation, such as anti-silt sediment reduction. As of 2011, the cumulative sedimentation is 23.76 million cubic meters, which is 5.85% of the initial gross capacity of 406 million cubic meters. The average sediment is 864,000 cubic meters (0.2%), far lower than Peishih Creek's estimated sand transportation of 1.136 million cubic meters. In recent years, with hydraulic de-silting operation running, from 2009 to 2011, the average annual sediment is 323,000 cubic meters, which is only 0.08% of the reservoir's initial gross capacity. Therefore, sedimentation has no impact on the operation of the reservoir at present time.
