Duduma Waterfall
"The 175-Meter Horsetail Giant of the Machkund River Gorge"
Duduma Waterfall is a colossal 175-meter (574 feet) horsetail plunge waterfall formed by the Machkund River on the Eastern Ghats escarpment along the border of Koraput District in Odisha and Alluri Sitharama Raju District in Andhra Pradesh. Ranked among the tallest waterfalls in peninsular India, Duduma is situated in the ancestral heartland of the ancient Bonda (Remo) tribe and powers the historic 1955 Machkund Hydroelectric Project.
1. Overview, Topography & Identity
Plunging with staggering velocity off the high Eastern Ghats tableland in southern Odisha, Duduma Waterfall is one of the most formidable natural spectacles in India. Located near Lamtaput and Onukudelli in Koraput district along the border with Andhra Pradesh, the waterfall hurtles 175 vertical meters (574 feet) down a sheer granite amphitheater into the deep Machkund River gorge.
The Machkund River & Sal Forest Wilderness
The journey to Duduma winds through rolling hills of tall Sal (*Shorea robusta*) forests, terraced indigenous rice paddies, and fragrant coffee plantations. Sitting at the edge of the elevated Koraput plateau, Duduma commands a vast, wild landscape where the acoustic roar of falling water resonates across misty ravines.
Koraput Tribal Coffee & High-Altitude Agroforestry
The high-altitude plateaus of Koraput (800–1,100m MSL) have gained global recognition for cultivating organic shade-grown **Koraput Coffee** under the native forest canopy. Grown primarily by indigenous tribal farming cooperatives, the Arabica beans flourish in the mist-laden microclimate fed by the Machkund and Kolab river valleys, creating an enriching agricultural backdrop along the highway to the falls.
Formed by the Machkund River (traditionally meaning "The River of Fish"), the cataract has served for millennia as a sacred boundary landmark and water source for indigenous tribes inhabiting the Eastern Ghats.
2. Geology: Eastern Ghats Granulite Scarp & Machkund Knickpoint
The geological framework of Duduma belongs to the Eastern Ghats Mobile Belt, composed of high-grade charnockites and khondalite rocks formed over 1.8 billion years ago during Proterozoic tectonic collision.
175-Meter Knickpoint Geomorphology
The Machkund River flows across the hard granulite plateau before encountering a dramatic fault escarpment. The river narrows into a rocky funnel before shooting over the cliff edge as a single, concentrated horsetail jet, dropping 175 meters into a violent plunge pool before winding through the deep canyon toward the Godavari River basin.
3. Bonda (Remo) Tribal Heritage & Onukudelli Weekly Market
Duduma Waterfall is located in one of India's most anthropologically significant cultural regions:
The Bonda (Remo) Ancient Community
The surrounding Bonda Hills are home to the **Bonda (Remo) tribe**, recognized as one of India's most ancient Particularly Vulnerable Tribal Groups (PVTGs), speaking an Austroasiatic language and maintaining distinct cultural traditions, brass neck rings, and woven beadwork. On Thursdays, the nearby village of **Onukudelli** hosts a famous weekly tribal market (*Haat*) where Bonda, Gadaba, and Didayi villagers barter organic forest produce and handmade crafts.
Matsya Tirtha Sacred Fish Sanctuary
According to ancient regional lore, the upper pools of the Machkund River above Duduma are revered as **Matsya Tirtha** (The Sacred Fish Sanctuary). Devotees believe that the mountain streams were blessed during the Treta Yuga, and the resident river fish (*Tor tor* / Mahseer) are considered sacred protectors of the waterfalls, strictly protected from fishing by tribal taboos.
4. The 1955 Machkund Hydroelectric Project (MHEP) History
Duduma is a historic milestone in India's early post-independence engineering and interstate cooperation:
Jalaput Dam & Inter-State Hydel Station
In 1955, the governments of Odisha and Andhra Pradesh jointly commissioned the **Machkund Hydroelectric Project (MHEP)**. The upstream **Jalaput Dam** stores monsoon waters, diverting regulated flow through mountain tunnels and steel penstock pipes down the 175-meter natural hydraulic head to the powerhouse situated at the gorge base, generating clean hydroelectricity for both states.
The project represents one of the earliest joint river valley developments in post-independence India, utilizing the extreme topological gradient of the Eastern Ghats escarpment without requiring extensive ecological flooding of the downstream gorge.
Authentic Koraput Tribal & Andhra Border Gastronomy
Exploring the highland tribal markets and heritage towns around Koraput, Jeypore, and Machkund offers a deeply authentic culinary journey combining indigenous tribal foraging with rustic Andhra-Odisha border flavors:

- Arakku / Bamboo Chicken: Marinated chicken chunks seasoned with wild forest herbs and onions, packed tightly into hollow green bamboo culms, and slow-roasted over burning wood embers without added water or oil.
- Koraput GI-Tagged Organic Coffee: World-class shade-grown Arabica coffee harvested by tribal farmers across the misty high plateaus of Koraput and Deomali, offering rich floral and chocolate notes.
- Gongura Mamsam & Mudhi: Fiery Andhra-border mutton curry flavored with tangy red sorrel leaves (*Gongura*), paired with crisp puffed rice (*Mudhi*) or unpolished hill paddy.
Onukudelli Weekly Haat & Tribal Food Culture
Every Thursday, the vibrant weekly tribal market (*Haat*) at **Onukudelli** comes alive where indigenous Bonda and Gadaba women trade forest honey, sun-dried mahua flowers, wild roots, hand-woven *Ringa* cloth, and traditional fermented beverages like *Salap* (sago palm wine) and *Handia*.
5. Seasonal Hydrodynamics & Month-by-Month Matrix
Discharge at Duduma is regulated by both monsoon rains and Jalaput Dam releases:

| September – November (Peak Post-Monsoon) | Colossal roaring torrent; massive white spray plumes | Pleasant mountain breeze; verdant hillsides | Best overall visit window & dramatic scenery |
| December – February (Winter) | Clean, steady powerful horsetail plunge; clear views | Cool, crisp mornings (10°C–22°C); sunny days | Optimal for photography & Onukudelli Haat |
| March – May (Summer) | Moderated flow governed by hydel generation releases | Warm days (28°C–36°C); clear canyon roads | Accessible off-peak sightseeing |
| June – August (Monsoon Inflow) | Rising water volume with heavy catchment downpours | Cloudy, humid; dramatic mist in gorge | Scenic road transit season |
