Krishna River
The Krishna River is a river in the Deccan plateau and is the third-longest river in India, after the Ganges and Godavari. It is also the fourth-largest in terms of water inflows and river basin area in India, after the Ganges, Indus and Godavari. The river, also called Krishnaveni, is  long and its length in Maharashtra is 282 kilometres. It is a major source of irrigation in the Indian states of Maharashtra, Karnataka, Telangana and Andhra Pradesh. Course
The Krishna River originates in the Western Ghats near Mahabaleshwar at an elevation of about , in the state of Maharashtra in central India. From Mahabaleshwar it flows to the town of Wai and continues to travel east until it empties into the Bay of Bengal. The Krishna River passes through the Indian states of Maharashtra, Karnataka, Andhra Pradesh, and Telangana. It is around  in length, of which  flows in Maharashtra,  in Karnataka and  in Andhra Pradesh. Tributaries

The Krishna River has 13 major tributaries. Its principal tributaries include the Ghataprabha River, Malaprabha River, Bhima River, Tungabhadra River and Musi River. The Tungabhadra River has a catchment area of  and a length of . The Bhima River is the longest tributary of the Krishna River. It has a total length of  and catchment area of . Three tributaries Panchganga, Warna and Yerla meet Krishna river near Sangli. These places are considered very holy. It is said that Lord Dattatreya spent some of his days at Audumber on the banks of river Krishna. Kudalasangama (also written as Kudala Sangama) is located about  from the Almatti Dam in Bagalkot district of Karnataka state. The Krishna and Malaprabha rivers merge here. The Aikya Mantapa or the holy Samādhi of Basavanna, the founder of the Lingayat sect of Hindu religion along with Linga, which is believed to be self-born (Swayambhu), is here and river flow east towards Srisailam (another pilgrim center) Andhra Pradesh. Sangameswaram of Kurnool district in Andhra Pradesh is a famous pilgrim center for Hindus where Tungabhadra and Bhavanasi rivers join the Krishna river. The Sangameswaram temple is now drowned in the Srisailam reservoir, and visible for devotees only during summer when the reservoir's water level comes down. Krishna Basin

The Krishna Basin extends over an area of  which is nearly 8% of the total geographical area of the country. This large basin lies in the states of Karnataka (113,271 km2), Telangana, Andhra Pradesh (76,252 km2) and Maharashtra (69,425 km2). It is the fifth largest basin in India. Most of this basin comprises rolling and undulating country, except for the western border, which is formed by an unbroken line of the Western Ghats. The important soil types found in the basin are black soils, red soils, laterite and lateritic soils, alluvium, mixed soils, red and black soils and saline and alkaline soils. An average annual surface water potential of 78.1 km3 has been assessed in this basin. Out of this, 58.0 km3 is utilizable water. Culturable area in the basin is about , which is 10.4% of the total cultivable area of the country. As the water availability in the Krishna river was becoming inadequate to meet the water demand, Godavari River is linked to the Krishna river by commissioning the Polavaram right bank canal with the help of Pattiseema lift scheme in the year 2015 to augment water availability to the Prakasam Barrage in Andhra Pradesh. The irrigation canals of Prakasam Barrage form part of National Waterway 4. The Krishna-Godavari delta known as "Rice Granary of India." Mineral deposits

Krishna river basin is endowed with rich mineral deposits such as oil & gas, coal, iron, limestone, dolomite, gold, granite, laterite, uranium, diamonds, etc. The following are the few noted deposits:

Flora and fauna

Wide spread area near to the Krishna river holds the rich flora and fauna. The last surviving Mangrove forests in the Krishna estuary have been declared as the Krishna Wildlife Sanctuary. The sanctuary is the home to the large number of resident and migratory birds. Fishing cats, otters, Estuarine crocodiles, spotted deer, sambar deer, blackbucks, snakes, lizards and jackals can also be spotted in the sanctuary. The sanctuary also supports rich vegetation with plants like Rhizophora, Avicennia, and Aegiceros. The following are few other wildlife sanctuaries located in the Krishna basin.

Water outflows to the sea
The yearly water outflows to the sea in a water year from 1 June 2003 to 31 May 2022 (19 years) are given below

Interstate water sharing

At present, the award of Bachawat tribunal dated 31 May 1976 is applicable for sharing the water available in the river among the riparian states. The Brijesh Kumar tribunal award given on 29 November 2013 is challenged by Andhra Pradesh in the Supreme Court and the case is pending since then. The newly created state of Telangana also approached the Supreme Court demanding a fresh tribunal hearing to secure its water needs on equitable basis. Even though the river does not flow through Tamil Nadu, the Telugu Ganga Project is a canal system that brings Krishna river water to that state's capital city of Chennai with the agreement of all basin states. Places and temples

This river is revered by Hindus as sacred. The river is also believed to remove all sins of people by taking a bath in this river. The centre of attraction is the Krishna Pushkaram fair which is held once in twelve years on the banks of the Krishna river.

The Krishna River is spanned by several bridges along its course, some of which are listed below. Krishna Bridge, Wai, Maharashtra – This bridge was demolished in 2021 which was located in the Dharmpuri Peth area of the town of Wai, was one of the oldest bridges that were built by the British in India. It spans the Krishna over nine kamans (arches) and is made of black rock. The bridge serves as a flood mark (when the water rises to the level of the road on the bridge) for the "Waikar" people. Irwin Bridge, Sangli – This is one of the oldest, historic and largest bridges over the Krishna that were built by the British. The Irwin Bridge, which is built of reddish stone, has two passages where one can climb down to the river in the middle of its span to view the water. Ankali Bridge, Sangli Maharashtra – This bridge is major link between Sangli and Kolhapur districts. At this point there are three bridge, one for railway and two for roadways. Out of two roadway bridge the one bridge in the direction towards Miraj was built in Nineteenth century under British Administration. It is still in operation. The railway bridge was constructed at the time of laying of Kolhapur to Pune rail link. The contractor for rail bridge was V. R. Ranade & Sons from Pune. The construction of this railway bridge and culverts on railway route in nearby region were constructed by them in year 1882–84. Kudachi – Ugar Railway bridge built by the British in 1891. B. Soundatti Bridge, Raibag – This is also one of the oldest bridges built during the British rule. This bridge connects Maharashtra to Karnataka state. Tangadagi Bridge, This is one of oldest bridges that connects the Bijapur and Bagalkot districts of Karnataka. God Neelambika Temple is there at the bank of Krishna River. Chikkapadasalagi bridge, is one of the oldest bridge built in British era connects jamakhandi and vijayapur, 
 Jambagi Bridge, Jamkhandi : Recently built bridge connects Athani , Bijapur and Jamkhandi. Galagali Bridge of Galagali village, Bagalkot: very important bridge that connects many towns and villages of Bagalkot and Vijayapur districts. Krishna Bridge near Shakti Nagar, Raichur distrcit was built in the memory of the travel undertaken by Nawab Javvadjaha Bahadur, the prince of Hyderabad, to Raichur in early 20th century. The bridge was named after the prince as Sirat-e-joodi. The construction began in 1933 and completed in 1943

In October 2009, heavy floods occurred, isolating 350 villages and leaving millions homeless, which is believed to be first occurrence in 1000 years. The flood resulted in heavy damage to Kurnool, Mahabubnagar, Guntur, Krishna and Nalagonda Districts. The entire city of Kurnool was immersed in approximately  water for nearly 3 days. Water inflow of  was recorded at the Prakasam Barriage, which surpassed the previous record of  recorded in the year 1903. Krishna river is the second largest east flowing river of the peninsula. The flood waters of Krishna and Godavari rivers can be fully utilized by exporting water to other east flowing peninsular rivers up to Vaigai River in Tamil Nadu by constructing a coastal reservoir on the Bay of Bengal sea area.

Hydroelectric power stations
Krishna river is one of the rivers whose water energy is harnessed to a large extent by various hydro electric power stations in India. The following is the list of hydro electric power stations excluding small and medium installations. Pollution
Most of the years, the river water is not joining the sea due to full utilisation of water mainly in agriculture. Closed river basin of Krishna means that the river ecosystem is on the verge of death. The river receives the waste from the large number of cities and the river basin population has increased to 80 million enhancing pollution load many folds into the river. Adequate average and minimum continuous environmental flows to the sea are not taking place in most of the years constricting salt export and leading to formation of saline and sodic alkaline soils in the lower reaches of the river basin. High alkalinity water is discharged from the ash dump areas of many coal fired power stations into the river which further increases the alkalinity of the river water whose water is naturally of high alkalinity since the river basin is draining vast area of basalt rock formations. The following are the few coal fired power stations located in the river basin
