Godavari and Krishna delta canal networks support farming across administrative districts. Kharif and Rabi delivery can differ with monsoon inflow, reservoir operation and crop demand. The Kakinada water-resources page notes that a barrage designed for one seasonal pattern has been managed for additional seasonal cropping.
Do not assume a physical canal guarantees water every day or every season. To answer a current supply question, use the water-resources bulletin or canal schedule with a date.
Worked example: A delta canal can support paddy in a season, but cropping area responds to rainfall, release timing and farmers' choices. Kharif and rabi are seasons, not names of canals. If an MCQ asks which region is associated with a delta system, use the Godavari or Krishna coast. If it asks actual irrigated hectares, use the season's official return and ensure its boundary vintage matches the district names.
Active recall: Locate the named river or project on the relevant map, name its function, and state which facts need a dated source.
