📖 Major rivers of Andhra Pradesh
- Godavari — the largest river flowing through AP, forming a fertile delta region near its mouth; supports extensive irrigation and inland navigation.
- Krishna — the second-major river, also forming a significant delta; shared with neighbouring states, leading to periodic inter-state water-sharing disputes.
- Penna (Pennar) — a smaller but locally important river flowing through the Rayalaseema region, supporting irrigation in an otherwise drought-prone area.
💧 Key irrigation projects
- Polavaram Project — a major multi-purpose project on the Godavari, providing irrigation, drinking water, and hydropower, and considered a "national project."
- Nagarjuna Sagar Dam — on the Krishna river, one of the world's largest masonry dams, supporting irrigation across both Andhra Pradesh and Telangana.
- Srisailam Dam — also on the Krishna, primarily for hydropower generation alongside irrigation support.
⚖️ Inter-state water disputes
Since the Krishna and Godavari rivers are shared with neighbouring states, water allocation has been a recurring source of inter-state tension, managed through various tribunals and agreements — a topic frequently tested alongside the specific projects themselves.
