🧱 Dams & Reservoirs of UP

Dams & Reservoirs of Uttar Pradesh

UP is primarily a plains state with limited dam-building potential compared to hilly states. However, the southern Vindhyan region and bordering areas host several important dams for irrigation and power generation.

The lesson becomes much easier if we divide structures into two groups:

• storage dams and reservoirs, mostly important in Sonbhadra and Bundelkhand
• barrages and weirs, which mainly divert river water into canal systems across the plains

Rihand Dam — UP's Largest Dam

Parameter	Detail
Location	Pipri, Sonbhadra district
River	Rihand River (tributary of Son)
Built	1962
Type	Concrete gravity dam
Height	~91 m (934 m length)
Reservoir	Govind Ballabh Pant Sagar
Reservoir distinction	Largest artificial lake in India (at time of construction)
Reservoir area	~468 sq km
Hydropower	300 MW capacity (Rihand Hydro Power Station)
Irrigation	Supports agriculture in Sonbhadra and Mirzapur

The Govind Ballabh Pant Sagar is named after Govind Ballabh Pant, who served as the first Chief Minister of Uttar Pradesh and later as Union Home Minister. It is a major reservoir of south-eastern UP and also supports fisheries.

Matatila Dam

Parameter	Detail
Location	Lalitpur-Jhansi border
River	Betwa River
Built	1958
Type	Masonry gravity dam
Height	~32 m
Purpose	Irrigation for Jhansi, Jalaun, and Hamirpur districts
Canal system	Matatila Canal irrigates Bundelkhand region
Significance	One of the earliest post-independence dams in UP

Matatila matters because Bundelkhand is a drought-prone region. So when exams ask why this dam is important, the answer is not just the river name; it is its role in irrigation support for a water-stressed region.

Rajghat Dam

Parameter	Detail
Location	UP-MP border (near Lalitpur)
River	Betwa River
Built	Completed 1999
Type	Joint project of UP and MP governments
Height	~44 m
Purpose	Irrigation and hydropower
Irrigation	Benefits both UP (Bundelkhand) and MP
Hydropower	45 MW installed capacity
Reservoir	Rajghat Reservoir

Rajghat is a good example of an inter-state water structure. In UP GK, it is often remembered as a UP-MP joint Betwa project.

Parichha Dam

Parameter	Detail
Location	Jhansi district
River	Betwa River
Purpose	Water supply and thermal power cooling
Key link	Supplies water to Parichha Thermal Power Station (1,360 MW)
Irrigation	Supplements canal irrigation in Jhansi area

Parichha is more useful to remember as a supporting structure in the Betwa system than as a major stand-alone storage dam.

Other Notable Dams

Dam	River	District	Key Detail
Obra Dam	Rihand	Sonbhadra	99 MW hydropower + thermal complex nearby
Sirsi Dam	Belan system	Sonbhadra/Mirzapur region	Small irrigation role in the Vindhyan belt
Parichha Weir	Betwa	Jhansi	Old diversion structure associated with irrigation and local water use

Major Barrages in UP

Barrages are different from dams — they are low-height structures that divert water into canals rather than creating a large deep storage reservoir.

Barrage	River	District	Purpose
Narora Barrage	Ganga	Bulandshahr	Headworks for Lower Ganga Canal
Bijnor / Madhya Ganga Barrage	Ganga	Bijnor	Headworks linked to the Madhya Ganga Canal system
Sharda Barrage	Sharda	Lakhimpur Kheri region	Headworks for Sharda Canal, Terai irrigation
Banbasa Barrage	Sharda	Uttarakhand border region	Important to the wider Sharda canal irrigation system serving UP
Girija Barrage	Ghaghra	Bahraich	Irrigation and regulation in the Ghaghra-Saryu system
Rapti Barrage	Rapti	Shravasti/Bahraich region	Flood management and irrigation support

Hydroelectric Power from UP Dams

Station	Dam/River	Capacity	District
Rihand Hydro	Rihand Dam	300 MW	Sonbhadra
Obra Hydro	Obra Dam	99 MW	Sonbhadra
Rajghat Hydro	Rajghat Dam	45 MW	Lalitpur
Anpara Thermal (nearby)	Son basin	2,630 MW	Sonbhadra

Sonbhadra district is called the "Energy Capital of UP" — it hosts Rihand, Obra, Anpara, and multiple thermal plants.

Dams and Irrigation Potential

Region	Key Dam/Barrage	Rivers Harnessed	Irrigation Type
Bundelkhand	Matatila, Rajghat, Parichha	Betwa, Ken	Canal irrigation
Sonbhadra-Vindhyan	Rihand, Obra	Son, Rihand	Reservoir + canal
Terai-Rohilkhand	Sharda Barrage, Banbasa	Sharda	Canal irrigation
Upper Ganga	Narora Barrage	Ganga	Canal irrigation
Eastern UP	Ghaghra Barrage	Ghaghra	Flood control + canal

Despite these dams, UP's primary irrigation source remains tube wells (~70%), not canals. Dam-based canal irrigation accounts for only ~20% of total irrigated area.
