The Bili-Bili Dam is a dam located in Gowa Regency, South Sulawesi, Indonesia, on the Jeneberang River, about 30 km from the city of Makassar. It provides flood control, irrigation, and hydroelectric power generation. The dam was constructed between 1991 and 1998.

Background

In 1981, Bili-Bili Dam was added to the Jeneberang River Comprehensive Development Project. Construction began in 1991 and the dam was completed in 1998. The weirs downstream of the dam and their accompanying irrigation canals were completed in December 2005. The dam's power station was commissioned in 2005 as well. [2] The project was built with funding and cooperation from the Japan International Cooperation Agency. It has several purposes to include municipal water supply for the city of Makassar, about 30 km away, and to protect the city from historic flooding. It is designed prevent an estimated 50-year flood. Water from its reservoir also helps irrigate about 23,786 ha (58,780 acres) of rice fields in Gowa and Takalar regencies. [3] The power station has an installed capacity of 19.25 MW and generates about 69,000 MWh of electric power each year. [3] [1]

Sedimentation in the reservoir has been a concern since at least 2004. The dam is downstream from Mount Bawakaraeng, which is "prone to landslides." [4] A large landslide in 2004 prompted a request for survey assistance to the Japanese government to determine the possible impact on the dam. [5]

An overflow of the dam in 2019 caused a major flooding. [6]

Design

The Bili-Bili Dam is a 1,800 m (5,900 ft) long and 73 m (240 ft) tall rock-fill type. Its reservoir holds 375,000,000 m3 (304,000 acre⋅ft) of water. [7] Below the dam are three weirs, the Bili-Bili, Bissau and Kampili. They connect to 61.2 km (38.0 mi) of primary canals and 228.1 km (141.7 mi) of secondary canals. The Bili-Bili weir covers about 2,444 ha (6,040 acres) of farmland while the Bissau covers 10,795 ha (26,680 acres) and Kampili 10,547 ha (26,060 acres). [2]

The Kings River, is a 132.9-mile (213.9 km) river draining the Sierra Nevada mountain range in central California in the United States. Its headwaters originate along the Sierra Crest in and around Kings Canyon National Park and form the eponymous Kings Canyon, one of the deepest river gorges in North America. The river is impounded in Pine Flat Lake before flowing into the San Joaquin Valley southeast of Fresno. With its upper and middle course in Fresno County, the Kings River diverges into multiple branches in Kings County, with some water flowing south to the old Tulare Lake bed and the rest flowing north to the San Joaquin River. However, most of the water is consumed for irrigation well upstream of either point.

As there was water deficiency in the Kodayar Irrigation System, Perunchani Dam was constructed in December 1952 to store flood water of the Paralayar River as an extension. It was built about 1 km (0.62 mi) upstream of the Puthen dam on the Paralayar River. The irrigation system became operational on 2 September 1953. It feeds the left bank irrigation canal system of the Puthen dam, which is the terminal structure of the system.

The Minidoka Project is a series of public works by the U.S. Bureau of Reclamation to control the flow of the Snake River in Wyoming and Idaho, supplying irrigation water to farmlands in Idaho. One of the oldest Bureau of Reclamation projects in the United States, the project involves a series of dams and canals intended to store, regulate and distribute the waters of the Snake, with electric power generation as a byproduct. The water irrigates more than a million acres (4,000 km²) of otherwise arid land, producing much of Idaho's potato crop. Other crops include alfalfa, fruit and sugar beets. The primary irrigation district lies between Ashton in eastern Idaho and Bliss in the southwestern corner of the state. Five main reservoirs collect water, distributing it through 1,600 miles (2,600 km) of canals and 4,000 miles (6,400 km) of lateral distribution ditches.

The primary purpose of the dam is irrigation but it will also provide for flood control, water supply and hydroelectric power generation. Water in the reservoir will be used to help irrigate 90,000 ha of farmland and the power station is expected to have a 110 MW capacity. The project has become controversial, primarily due to the relocation of people in the future reservoir zone.

<span class="mw-page-title-main">Middle Rio Grande Project</span>

The Middle Rio Grande Project manages water in the Albuquerque Basin of New Mexico, United States. It includes major upgrades and extensions to the irrigation facilities built by the Middle Rio Grande Conservancy District and modifications to the channel of the Rio Grande to control sedimentation and flooding. The bulk of the work was done by the United States Bureau of Reclamation and the United States Army Corps of Engineers in the 1950s, but construction continued into the 1970s and maintenance is ongoing. The project is complementary to the San Juan–Chama Project, which transfers water from the San Juan River in the Colorado River Basin to the Rio Grande. Although distribution of water from the two projects is handled through separate allotments and contracts, there is some sharing of facilities including the river itself. The ecological impact on the river and the riparian zone was the subject of extended litigation after a group of environmentalists filed Rio Grande Silvery Minnow v. Bureau of Reclamation in 1999.
