In which year check dams were build on the Rukmavati river and its tributaries?
Answer & explanation
Correct answer: option 3
The correct answer is option 3. 1989.
In 1989, the villagers along with a non-governmental organization, decided to harvest rainwater. Eighteen check-dams were built on the Rukmavati river and its many tributaries. The water so collected increased percolation through the soil and recharged the aquifers.
