Answer:

River Yamuna and percentage of oxygen in Yamuna

Explanation:

Yamuna river happens to be one of the most legendary rivers of Northern India.But now it has become extremely polluted these days.

Current condition of the Yamuna River - an overview of flow, pollution load and human use

Introduction

Yamuna is the sub-basin of the Ganga river system. Out of the total catchment’s area of 861404 sq km of the Ganga basin, the Yamuna River and its catchment together contribute to a total of 345848 sq. km area which 40.14% of total Ganga River Basin (CPCB, 1980-81; CPCB, 1982-83). It is a large basin

covering seven Indian states. The river water is used for both abstractive and in stream uses like

irrigation, domestic water supply, industrial etc. It has been subjected to over exploitation, both in

quantity and quality. Given that a large population is dependent on the river, it is of significance to

preserve its water quality. The river is polluted by both point and non-point sources, where National

Capital Territory (NCT) – Delhi is the major contributor, followed by Agra and Mathura. Approximately,

85% of the total pollution is from domestic source. The condition deteriorates further due to significant water abstraction which reduces the dilution capacity of the river. The stretch between Wazirabad barrage and Chambal river confluence is critically polluted and 22km of Delhi stretch is the maximum polluted amongst all. The Yamuna river originates from the Yamunotri glacier near Bandar Punch (38o 59' N 78o 27' E) in the Mussourie range of

the lower Himalayas at an elevation of about 6320 meter above mean sea level in the district Uttarkashi

(Uttranchal). The catchment (table 1&2) of the Yamuna river system covers parts of the states of

Uttaranchal, Uttar Pradesh (U.P.), Himachal Pradesh, Haryana, Rajasthan, Madhya Pradesh and the

entire state of Delhi. The river Yamuna traverses a distance of about 1370 km in the plain from

Saharanpur district of Uttar Pradesh to the confluence with river Ganga at Allahabad.

Name of state Total catchment area in Yamuna (in Sq. Km.) %age contribution

U.P. (including Uttranchal) 74208 21.5

Himachal Pradesh 5799 1.6

Haryana 21265 6.5

Rajasthan 102883 29.8

Madhya Pradesh 14028 40.6

Delhi 1485 0.4

Answer 2

Uttarakhand - 56 %

Himachel Pradesh -33%

Delhi - 16%

Haryana -14%

Uttar Pradesh - 10%

Explanation:

• Yamuna River is the major/pivotal river of northern India, and is one of the nation’s most-sacred rivers.
• Yamuna is one of the most polluted rivers in the nation
• The oxygen levels have considerably reduced in the states  where the Yamuna River passes because of  industrial effluents, untreated sewage, dumping of dead bodies, the dumping of garbage, immersion of idols & pollution because of in-stream uses of water
