Step 1: Recall the Nagarjunasagar project.
The Nagarjunasagar dam is one of the largest masonry dams in the world. It was built for irrigation, hydroelectric power generation, and water supply purposes.
Step 2: Identify the river.
The project is situated in Andhra Pradesh and Telangana on the Krishna River. It provides irrigation to a large command area and is a landmark multipurpose river valley project in India.
Step 3: Eliminate other rivers.
- Godavari River is the site of projects like Polavaram and Jayakwadi, not Nagarjunasagar.
- Pennar River has smaller irrigation projects, but not Nagarjunasagar.
- Mahanadi River has the Hirakud Dam, not Nagarjunasagar.
Step 4: Conclusion.
Therefore, Nagarjunasagar project was established on the Krishna River.
Final Answer: \[ \boxed{\text{Nagarjunasagar project is on the Krishna River.}} \]
