Nakti Dam Wildlife Sanctuary

Overview: The Deep-Water Sanctuary of Jamui

Located just 4 kilometers from its twin reservoir Nagi Dam in the Jhajha block of Jamui district, Nakti Dam Wildlife Sanctuary covers approximately 3.32 square kilometers of pristine upland aquatic and scrubland habitat.

Established in 1984 under the Wildlife (Protection) Act and officially designated as **Ramsar Site No. 2542** in 2024, Nakti Dam complements the open-shallow topography of Nagi by offering a significantly deeper, rocky reservoir basin. Impounded on the seasonal Nakti River amidst granitic ridges and boulder-strewn hillocks, the sanctuary provides a critical specialized niche for diving waterbirds that require deeper columns of clear water to forage for benthic plants, roots, and aquatic molluscs.

Together, the twin sanctuaries of Nagi and Nakti form a cohesive, 11-square-kilometer wetland conservation complex that anchors avian diversity across the drought-prone southern plateau fringe of Bihar. While Nagi attracts staggering congregations of grazing geese, Nakti serves as an essential sanctuary for diving ducks, grebes, and secretive marsh birds.

Hydro-Geomorphology & Specialized Depth Niches

Nakti Dam is set within an ancient pre-Cambrian granitic landscape characterized by steep rock faces, natural quartz veins, and deep gully catchments. The reservoir water is notably clear, with low turbidity, allowing sunlight to penetrate to depth and stimulating the growth of submerged aquatic weeds such as Potamogeton, Hydrilla, and Chara.

The distinct bathymetry of Nakti Dam creates a multi-layered vertical water column that supports diverse avian feeding strategies:

Because Nakti Dam is enclosed by steeper terrain than Nagi, it experiences less evaporative surface loss during early summer, retaining deeper perennial water pockets through March and April. This hydrological stability ensures that late-departing winter migrants and resident breeding birds have a dependable refuge when surrounding seasonal village tanks have completely dried out.

Avian Assemblages & Diving Waterfowl Diversity

Over 130 bird species have been recorded at Nakti Dam. The sanctuary is especially renowned among ornithologists for its winter populations of threatened diving duck species:

Additional avifauna regularly sighted across the reservoir and its shoreline include the Red-crested Pochard (Netta rufina), Common Teal (Anas crecca), Gadwall (Mareca strepera), Black-necked Stork (Ephippiorhynchus asiaticus), Pied Kingfisher (Ceryle rudis), and the graceful White-bellied Sea Eagle during rare winter wanderings.

Terrestrial Flora & Soil Conservation Significance

The catchment hills of Nakti Dam are covered with Dry Deciduous Scrub and Thorn Forest comprising hardy, drought-tolerant flora:

• Canopy & Thicket Flora: Khair (Acacia catechu), Babul (Acacia nilotica), Palas (Butea monosperma), Ber (Ziziphus mauritiana), and Kendu (Diospyros melanoxylon).
• Watershed Protection & Soil Stabilization: The sanctuary's forested granitic catchment plays a critical hydrological role in preventing severe soil erosion, checking flash run-off during heavy monsoon downpours, and preserving underground water tables for agricultural communities across southern Jamui.
• Terrestrial Wildlife: Small Indian civet, jungle cat, Indian hare, monitor lizard, and Indian rock python thrive along the rocky boulder screes.

Participatory Conservation & Local Stewardship

In recent years, the Bihar Environment, Forest and Climate Change Department has actively partnered with local village communities surrounding Nakti Dam through Eco-Development Committees (EDCs).

Local youth and indigenous Santhal communities from adjacent villages have received professional training in bird identification, binocular handling, and ecotourism facilitation. Community members participate in seasonal waterfowl censuses, patrol the reservoir boundary against illegal gill-netting, and assist in maintaining bird observation watchtowers. This collaborative stewardship ensures that the Ramsar wetland status translates into tangible livelihood benefits and ecological pride for the region.

The Nagi-Nakti Twin Ecotourism Circuit

Because Nakti Dam is separated from Nagi Dam by a mere 4 kilometers of scenic village road, the Bihar Forest Department manages both sanctuaries as a single integrated conservation and ecotourism circuit.

Visitors typically begin their morning birding at Nagi Dam to witness the grand dawn flight of thousands of Bar-headed Geese, followed by a mid-day and afternoon exploration of Nakti Dam's watchtowers to observe diving ducks and raptors in the crystal-clear deep reservoir waters.
