YOGYAKARTA - Have you ever imagined what would happen if the water in the reservoir was dry? Reservoir drought is not just a visual problem, but also has a serious impact on various aspects of life.
Starting from the clean water crisis that threatens daily needs, agriculture that is threatened with crop failure, to the breakdown of the irreversible water ecosystem. In this article, we will thoroughly explore the impact of reservoir drought.
Reporting from the website of the Ministry of Public Works, the dry season causes three reservoirs in Central Java, namely Krisak, Ngancar, and Botok Reservoir, to experience drought. This makes people worried about the availability of raw water.
The PSDA Service explained that the three reservoirs that dried up were classified as small reservoirs and were used to experiencing drought during the dry season.
Central Java itself still has 22 other small reservoirs that are still filled, as well as eight large reservoirs that are able to meet the raw water needs of the community.
Large reservoirs such as Malayu, Cacaban, Rawapening, Kedungombo, Wonogiri, Semor, Wadaslintang, and Sudirman have an important role in supplying water for irrigation.
The large reservoir itself has a significant contribution in irrigating about 200,000 hectares of land, while small reservoirs irrigate 65,000 hectares. The total technical irrigation area that receives water supply from the reservoir reaches 265,000 hectares, or about 30% of the total irrigation area in Central Java. The rest still relies on water from the river.
In addition to drinking water reserves, reservoirs also have an important role in maintaining food sovereignty.

However, although the availability of water in the reservoir is still maintained, drought can begin to have an impact on river water discharge. For example, the eastern coastal areas, such as Jepara, Demak, Rembang, Kudus, Pati, and Grobogan, experienced a decrease in river water discharge.
However, other areas such as Pemalang, Batang, Semarang, and Kendal still have irrigation water supplies from rivers.
To overcome the impact of drought on rivers, local governments have taken steps such as providing clean water assistance through BPBD and the Ciptakaru Service. In addition, the PSDA Service also provided pump assistance to drain water from irrigation canals to agricultural land in need.
The PSDA Service also made rotating water arrangements, appealed to farmers to save water, and asked them not to plant rice during the dry season.
Based on the review above, it can be concluded that several things will happen if the reservoir water drys up, including:
Reservoir is often the main source of clean water for the community. Reservoir drought can cause a clean water crisis that has an impact on daily life, health, and sanitation.
The agricultural sector relies heavily on water supplies from reservoirs for irrigation. Reservoir drought can cause crop failure, leading to a food and economic crisis.
Reservoir drought disrupts the life of water biota and ecosystems in the vicinity. Natural habitats become damaged, biodiversity decreases, and can even lead to extinction of certain species.
