Krishnagiri Dam (Krishnagiri Reservoir Project)

Location and characteristics

The dam is situated by the village of Dhuduganahalli, roughly 7 km from the town of Krishnagiri and located on the route between Dharmapuri and Krishnagiri. It spans the Thenpennai (also known as the Ponnaiyar or South Pennar) River and creates a reservoir that feeds a network of canals and channels for downstream fields. The facility is often identified by its acronym, KRP Dam, and functions as a multi-purpose water control structure for the district.

• River: Thenpennai (Ponnaiyar)
• Nearby settlements: Dhuduganahalli village; close to Krishnagiri town
• Primary role: irrigation storage and regulation
• Secondary roles: local water supply, fisheries and recreation

History and development

The Krishnagiri project was completed and put into service in 1958 during a period of post-independence development when many medium-scale irrigation works were built across India. The inauguration was carried out by the then Chief Minister of Tamil Nadu, K. Kamaraj. Since its commissioning, the dam has been maintained by state irrigation authorities and has undergone routine repairs and management adjustments to match changing water demands and agricultural patterns.

Uses, benefits and local importance

The primary benefit of the KRP Dam is irrigation: its reservoir stores seasonal rains and releases water to cultivate thousands of acres of farmland in the Krishnagiri area. By regulating flows it reduces downstream flood peaks in heavy monsoon years and supports dry-season agriculture when river flows diminish. The reservoir also contributes to local livelihoods through small-scale fisheries, groundwater recharge near the command area and recreational uses that attract visitors from nearby towns.

1. Supports irrigation for multiple cropping cycles in the district
2. Helps stabilize water availability for villages and peri-urban users
3. Provides modest opportunities for fishing and leisure activities

Access, distinctions and further information

Because of its proximity to Krishnagiri town, the dam is a recognized local landmark and is accessible by road from the district headquarters. Visitors and researchers seeking administrative or technical details may consult district-level resources; for information related to the administrative unit see Krishnagiri district, and for directions or local services see Krishnagiri town. The KRP Dam exemplifies many medium-scale post-independence irrigation projects in southern India that continue to play a key role in rural water management.
