Dear student,
Kuhls are a traditional irrigation system in Himachal Pradesh. They are surface channels diverting water from natural flowing streams (khuds). A typical community kuhl services 6 to 30 farmers, irrigating an area of about 20 ha. The system consists of a temporary headwall (constructed usually with river boulders) across a khud (ravine) for storage and diversion of the flow through a canal to the fields.
By modern standards, building kuhls was simple, with boulders and labour forming the major input. The kuhl was provided with moghas (kuchcha outlets) to draw out water and irrigate nearby terraced fields. The water would flow from field to field and surplus water, if and, would drain back to the khud.
The kuhls were constructed and maintained by the village community.
You can get the figure for kuhls in the below site:
