About Uttarakhand Rivers
The water quality of Uttarakhand‘s rivers is basically good, especially in the upper reaches. Downstream of some large settlements and in the lower reaches in the Himalayan foot hills the water quality suffers due to the release of untreated sewage and industrial effluents. But the state‘s ambitious program to build 450 hydro power projects threatens the survival of the river ecosystems and the lives and livelihoods of people who live in these river valleys.
Summary of Rivers in Haryana
Location: Northwest India, Carved out of Punjab in 1st November 1966; Area: 44212 sq km. Mostly Gangetic/ Trans-Gangetic Plains; Population: 253.53 lakhs (2011); 4 River Basins, 21 Districts; Climate- Arid to semi-arid with average rainfall
Rivers in Haryana fall mainly within Indus and Ganga basins. River Ghaggar sub basin and its tributaries in the west of the state caters to the Indus basin, while river Yamuna and its tributaries in the east make up the portion of the Ganga basin.
Power surplus, power exporter India, with record solar& wind wind generation trend, why push more destructive hydro projects According to power ministry statement on March 29, 2017, India for the first time became NET EXPORTER OF ELECTRICITY during 2016-17, it exported 4% more power during last 11 months (April-Feb), that what it imported from Bhutan. At the same time, power plants, on a national average, are opera ting at roughly 60%, down from nearly 65% in 2014-15.
Meanwhile, the Cabinet Committee on Economic Affairs has approved the amendments in the Mega Power Policy to push 31 GW stuck projects entailing an investment of Rs 1.5 lakh crore. The stuck projects in mega power policy include hydro projects of above 350 Mw in designated states (J&K and eight NE states) and above 500 Mw in other states.
Amid this, New and Renewable Energy Ministry has added over 5400 Mw wind energy capacity in 2016-17 against the target of 4000 Mw. This year’s achievement surpassed the previous higher capacity addition of 3.423 Mw achieved in the previous year. The leading States in the wind power capacity addition during 2016-17 are Andhra 2190 Mw, followed by Gujarat 1275 Mw and Karnataka 882 Mw.
In the last couple of years, India has not only seen record low tariffs for solar power but wind power too has seen a significant drop in tariffs. The onshore wind power potential alone is about 302 Gw. Preliminary estimates show the Gujarat coastline has the potential to generate around 106,000 Mw of offshore wind energy and Tamil Nadu about 60,000 Mw.

Major Issues faced by Rivers of Maharashtra include complete lack of governance geared towards protecting rivers as ecological systems, unjustifiable dam projects blocking most of the rivers of the state without even comparable benefits, increasing water conflicts, depleting groundwater levels which affect base flow of the rivers, catchment degradation, climate change induced changes in river hydrology, repeated droughts and increasing levels of pollution.
The River system in North East, other than the Brahmaputra, can be classified as the Barak River system and minor Rivers flowing to Bangladesh and Burma. The Barak River, Gumti River, Myntdu River etc are some of the major Rivers flowing to Bangladesh, while the Kaladan River, the Manipur River, Tizu River etc flowing in the States of Mizoram, Manipur and Nagaland are main Rivers flowing to Burma.
The Barak River basin covers parts of India, Bangladesh and Myanmar. In India it spreads over states of Meghalaya, Manipur, Mizoram, Assam, Tripura and Nagaland having an area of 41,723 Sq.km.
The Barak River originates from the Manipur hills, from Liyai Village in Senapati district in Manipur at an elevation of 2,331 m and flows through Assam and further down to Bangladesh, where it is known by the name of the Surma and the Kushiyara and later called the Meghna before receiving the combined flow of the Ganga and the Brahmaputra. The principal tributaries of Barak joining from north bank are the Jiri, the Chiri, the Modhura, the Jatinga, the Harang, the Kalain and the Gumra whereas the Dhaleswari, the Singla, the Longai, the Sonai and the Katakhal joins from south bank. The Barak sub-basin lies in the States of Meghalaya, Manipur, Mizoram, Assam, Tripura and Nagaland.

About West Bengal Rivers
The state of West Bengal, a land of many rivers, covers an area of about 88,752 km2 and is the home of more than 90 million populations as per census of 2011. The Ganga divides the state into two unequal hubs: the North and South Bengal. The state has been divided into 20 districts, the seven districts are within North Bengal and remaining 13 districts are in South Bengal. West Bengal is the only state of India that extends from the Himalaya in the north to Bay of Bengal in south. It offers wide topographic diversity and intricate drainage network of 29 basins. The south Bengal can further be subdivided into two geographical units taking Bhagirathi-Hugli river (the western distributary of the Ganga) as the demarcating line. The western part is called Rarh Bengal and the eastern part is described deltaic Bengal. The rivers of West Bengal have been divided into five groups: i) the rivers of North Bengal; ii) the Ganga-Padma system; iii) the Bhagirathi- Jalangi-Churni system; iv) the western tributaries to Bhagirathi and v) the tidal creeks of Sundarban.
Location: North West India; Area:- 342,239 sq km; Geography:-Desert plains and mountainous (Aravalli range); Population:- 68.54 million People; Rivers:- 6 Major River basins; Districts:-33 Districts; Climate:- Drier Western and Tropical Eastern part
About Rajasthan Rivers
Rivers in Rajasthan are mostly seasonal, but this fact explains little because a river is not just the surface flow, evident to a naked eye. All the rivers and their floodplains in this desert state are vast grazing grounds supporting millions of livestock. These unseen rivers also recharge the groundwater making well irrigation possible.
Modern-day development activities, however, are putting an enormous pressure on them. If deforestation has reduced the water flow, rampant sand mining has affected the water retention and seepage into subsurface channels. Aravallis also has large number of marble mines and processing units. While digging operations extensively damage the environment, discharge of a large amount of slurry by processing units also blocks water channels. Industrial and domestic wastewater has further affected the quality and biodiversity of rivers.

To say that rivers hold great cultural significance for South Asia is stating the obvious. Also obvious is that the cultural legacy of rivers overpowers the religious narrative… which too, is not tied only to Vedic Hinduism. All faiths in the subcontinent have a deep connection with rivers which manifests in stories, lore, songs and poetry. While Suktas in Rigveda eulogizing rivers are known, actually breathtaking is the lyrical beauty of the verses which describe Sindhu or Indus as a “wild, magnificent white stallion, roaring and galloping through the Himalayas into the plains” or sometimes as a “loving mother cow, its calves following her from the steep mountain paths”.

Ponds are an essential asset for our survival. They store rainwater and work as groundwater recharge points. They can also treat sewage to some extent. Not long back, ponds water was used for potable purposes. Since ancient time, they have been central to numerous cultural and economic activities. In fact, village communities had certain set of rules for the preservation of village ponds. But things seem to have changed drastically specially in urban areas in recent decades. Through this field report comprising of latest images, we try to present current status of ponds in and around Narela in Delhi city.
