Kakinada district water-resources material identifies the Yeleru Reservoir Project as a major project serving irrigation and industrial and drinking water needs. The Yeleru system lies in the eastern Godavari-side catchment region. A reservoir project can have multiple users: field irrigation, urban supply and industry may each be administered through different delivery rules.

Do not use a district headquarters to guess the reservoir point. Place Yeleru on the Godavari-side map, then distinguish stored water from water delivered to Visakhapatnam through a separate supply system.

Worked example: Yeleru is a reservoir name in the north-coastal water-system discussion. Do not place it on the Krishna merely because the question also mentions a major city or industrial demand. Locate the reservoir and trace the relevant supply route on the regional map. Supply purpose, storage volume and source river are separate claims; a changing volume should be taken from a dated reservoir table, never from an undated atlas caption.

Active recall: Locate the named river or project on the relevant map, name its function, and state which facts need a dated source.
