Headquarters: Eluru. The district occupies the transition from Godavari hinterland toward the Krishna basin and Kolleru wetland. Locate this district first in relation to the coast, the Godavari or Krishna corridors, the Eastern Ghats or the Rayalaseema plateau. These physical belts often reveal why a crop, port, reservoir or pilgrimage place appears in a district question. Read the number on the accompanying current-boundary map before memorising a headquarters. A town name on a pre-2022 map can remain correct geographically but lead to the wrong present-district option.
Exam anchor: Kolleru is a freshwater lake associated with the Godavari-Krishna delta region; Eluru town is the administrative anchor. This is a place-to-theme association, not a claim that every landmark in the surrounding region belongs inside the district. Keep a separate column for a river or landscape, a site or activity, and the administrative headquarters. In a map question, begin at the state outline, narrow to the regional belt, and only then select the district polygon. The order is more dependable than recognising a familiar town name in isolation.
Boundary and date caution: Do not assume every village around Kolleru belongs to Eluru district; the lake and its catchment cross administrative questions. District-level population, area, output and mandal totals are especially sensitive to reorganisation. An exact figure should carry its reference year and boundary vintage; this book does not silently attach an old census total to a new polygon. If the stem quotes an older notification, answer for that date. If it asks for the current district, use the 2026 map and official district portal.
Worked example: Eluru is a current district and headquarters, but it no longer serves as headquarters for the smaller modern West Godavari. Kolleru Lake helps orient this region between the major deltas. A pre-2022 district crop figure may cover areas now in separate districts; keep the original boundary vintage attached. A lake point does not assign every wetland hectare to one district.
Active recall: Name the headquarters of Eluru; place it on the map; give one physical-geography anchor and explain the dated boundary trap above.
