Agoden Reservoir is located at the eastern foothill of Mt.Siao-Kang, at the upstream end of A-KUNG-TINE Creek and inside Yen-Chao Hsiung, Kaohsiung County . It is a multipurpose reservoir with principal function of flood control besides irrigation and water supply. Since its completion in 1952, due to the pool geology in the catchment area, the reservoir is bearing an annual siltation of about 5 hundred thousand stere .Currently, the total siltation amounts to about 50% of the original reservoir capacity. This not only has hampered the operation irrigation and water supply but also results in cutting down the ability of flodd prevention to fifty-year flood frequency threatening dam safty, important facilities, life and properties of the inhabitants downstream. I n order to resolve the problem, The TPGWRD is undertaking a renovation and improvement program for the reservoir. The program has been approved by the Executive Yuan. The project is to be completed in eight year, beginning in 1998.
Planned goal
1. Increase reservoir's ability of flood prevention to ten thousand-year flood frequency to ensure dam, military, transportation facility and resident safety in the lower stream.
2. In view of reservoir flood prevention improvement, water supply potentials of the reservoir are also increased.
3. Undergo reservoir silt prevention operations as a perpetually utilized facility
4. Solve problems of reservoir flood mitigation, sedimentation, and water supply
Planned efficacy
1. Increase reservoir water capacity and flood retention space to increase ability of flood prevention to ten-thousand-year flood frequency to ensure dam, military, transportation facility and resident safety in the lower stream.
2. Stabilize agricultural irrigation water supply and increase annual public use water capacity to 2,900 stere.
3. After renovation, the way that opening gates and keeping nothing make the water bring away the silt begin to operate during the flood stage., which is the first actual reservoir silt prevention model testing conducted. This precious observatory data serves as reference for the perpetual utilization, planning and operation of reservoirs in Taiwan .
4. After renovation, the silt prevention project cover the returning of silts/mud produced in the catchment area to the seashore to ensure coastline balance.
