Krishna River Map & Tributaries Memory Trick

Introduction: Why the Krishna Matters

The Krishna is one of the major east-flowing peninsular rivers of India and the fourth largest in the country by annual water inflow after the Ganga, Godavari and Brahmaputra. It originates in the Western Ghats of Maharashtra and traverses the heart of southern India — Maharashtra, Karnataka, Telangana and Andhra Pradesh — before forming a large fertile delta and emptying into the Bay of Bengal.

For UPSC, SSC, RRB and State PSC aspirants, the Krishna is high-yield because of its clear left-bank vs right-bank tributary classification (Bhima vs Tungabhadra being the most important), major dams (Nagarjuna Sagar, Srisailam), the historic city of Hampi on the Tungabhadra, the pioneering Pattiseema Godavari-Krishna interlinking project, and the long-running Krishna Water Disputes Tribunal. Questions on its origin at Mahabaleshwar, city-river matching (Hyderabad on Musi, Vijayawada on Krishna), and comparison with Godavari appear regularly.

1. Origin, Course & Famous Features

The Krishna River rises from a freshwater spring at Mahabaleshwar in the Satara district of Maharashtra in the Western Ghats, at an elevation of about 1,337 metres.

It flows southeast through Maharashtra and Karnataka before entering Telangana and Andhra Pradesh. After passing through a narrow gorge in the Eastern Ghats, it enters the plains at Vijayawada. It eventually forms a massive, highly fertile wave-dominated delta and empties into the Bay of Bengal at Hamsaladeevi (near Avanigadda in Krishna district, Andhra Pradesh).

Watch the river originate in the Western Ghats, receive major tributaries (Bhima left-bank, Tungabhadra right-bank), pass key dams, and form the fertile delta.

2. Major Tributaries (Left-Bank & Right-Bank)

The Krishna basin has a well-distributed network of tributaries coming from both the north (left-bank) and south (right-bank).

Left-Bank Tributaries

• Bhima River — The longest tributary of the Krishna. Originates in the Bhimashankar hills (Western Ghats) of Maharashtra and flows through Karnataka to join the Krishna.
• Musi River — Famous because the historical city of Hyderabad is situated on its banks. Joins the Krishna in the Nalgonda district of Telangana.
• Dindi River — A minor perennial stream flowing through Telangana, feeding the underground water tables of the dry Nalgonda plateau.
• Paleru & Munneru — The easternmost left-bank tributaries that join the main river stem in Andhra Pradesh.

Right-Bank Tributaries

• Tungabhadra River — The largest tributary by water volume. Formed by the confluence of the Tunga and Bhadra, which originate in the Western Ghats (Kudremukh) of Karnataka. The capital of the ancient Vijayanagara Empire, Hampi, sits on its banks.
• Koyna River — Originates in Mahabaleshwar. Known as the “Lifeline of Maharashtra” due to its massive hydroelectric power capabilities. The Koyna Dam forms the Shivajisagar Lake.
• Ghataprabha & Malaprabha — Both originate in the Western Ghats of Karnataka. Ghataprabha is known for the scenic Gokak Falls.
• Panchganga & Dudhganga — Small, fast-flowing rivers draining the southern districts of Maharashtra before cutting into Karnataka.

3. Major Water Infrastructure and Dams

Due to its high drop in elevation across the Deccan Plateau, the Krishna holds vast potential for hydro-power generation and heavy canal irrigation.

• Almatti Dam (Lal Bahadur Shastri Dam) — Located in northern Karnataka. Key node of the Upper Krishna Project.
• Narayanpur Dam — Located downstream of Almatti in Karnataka, primarily used for agricultural water distribution.
• Srisailam Dam — Constructed inside a deep gorge in the Nallamala Hills along the border of Telangana and Andhra Pradesh. One of the largest strategic hydro-power stations in the country.
• Nagarjuna Sagar Dam — Located on the border of Telangana and Andhra Pradesh. Recognized as one of the earliest and largest masonry dams built during India’s Green Revolution era.
• Prakasam Barrage — Located at Vijayawada, Andhra Pradesh. Regulates the flow of water into the expansive Krishna delta canal systems.

4. Pattiseema Interlinking & Water Disputes

Pattiseema Lift Irrigation Scheme is a pioneering Indian river-linking project that diverts surplus floodwaters from the Godavari River to the water-deficit Krishna River basin. Water is lifted via a canal that ends above the Prakasam Barrage at Vijayawada, helping to augment irrigation in the Krishna delta.

Because the river flows through four rapidly industrializing and agricultural states, water distribution is a major constitutional issue. The Krishna Water Disputes Tribunal (KWDT) was set up in phases (KWDT-I in 1969, KWDT-II in 2004) to divide waters between Maharashtra, Karnataka and (then undivided) Andhra Pradesh. Allocations continue to be modified following the creation of Telangana.
