Kolleru Lake

Updated June 11, 2025

## Kolleru Lake (Kaikaluru area, Andhra Pradesh): what it is, why it matters, and what makes it a serious birding wetland

Kolleru Lake is a large freshwater wetland system in Andhra Pradesh, India, recognized internationally under the Ramsar Convention as a wetland of international importance. Sites Information Service It’s best understood not as a neat “lake with a shoreline,” but as a shallow, seasonally expanding water body sitting between two major river-delta landscapes in coastal Andhra.

### Fast facts (from primary references)
– Ramsar Site name / number: Kolleru Lake (Site no. 1209) Sites Information Service
– Ramsar designation date: 19 August 2002 Sites Information Service
– Ramsar listed area: 90,100 hectares Sites Information Service
– Ramsar coordinates (approx.): 16°37′N, 81°12′E Sites Information Service
– Geographic setting: between the Krishna and Godavari river deltas, near Eluru Britannica
– Seasonal expansion: Britannica notes it may expand to ~100 square miles (~260 km²) during the summer monsoon Britannica

(Your provided coordinates, 16.5675417, 81.2312794, are consistent with the Ramsar coordinate band for the site, but I’m not treating your coordinate as an “official” centroid—Ramsar’s listing is the authoritative coordinate reference.) Sites Information Service

## Where Kolleru Lake sits on the map — and why that’s the whole story

Kolleru lies between the Krishna and Godavari delta regions in northeastern Andhra Pradesh. Britannica That delta context matters because deltas are built on slow gradients, distributary channels, and seasonal pulses of water. In a landscape like this, “lake vs. wetland vs. floodplain” is often a sliding scale.

Britannica’s description underscores the seasonal behavior: Kolleru can expand significantly during monsoon conditions. Britannica That expansion is one reason it functions as more than a scenic water body—it’s part of a broader hydrological system that changes shape through the year.

## Why birdwatchers care: a wetland built for waterbirds

You’ve categorized it as a bird watching area, and that matches what the site is known for in conservation and wetlands literature: Kolleru is widely treated as a significant waterbird habitat. Its Ramsar status is a strong signal here: Ramsar designations are intended for wetlands of international importance, often (though not exclusively) for biodiversity and waterbird values. Sites Information Service

If you want a conservative, strictly sourced way to say this in a publish-ready guide:
– Kolleru is internationally recognized as a wetland of importance (Ramsar), and it lies in a deltaic landscape that supports wetland-dependent wildlife. Sites Information Service

I’m intentionally not listing specific bird species or seasonal peak windows in this post, because many online sources repeat those details inconsistently, and your “only return factual information you 100% know” constraint means sticking to top-tier references.

## Protection status: what is formally notified, and what government sources actually say

A highly useful, conservative reference here is a Government of India parliamentary document (Sansad/Q&A annex). It states:

– In 1999, the Government of Andhra Pradesh issued an order declaring 308 sq km of Kolleru Lake as Kolleru Wildlife Sanctuary under the Wildlife (Protection) Act, 1972. Sansad

That’s an unusually specific and reliable statement for a travel article because it ties date + legal instrument + protected-area extent to an official record.

### Why that matters for a visitor
“Ramsar site” and “wildlife sanctuary” aren’t the same thing:
– Ramsar is an international designation for wetland importance. Sites Information Service
– A wildlife sanctuary is a domestic protected-area category under Indian law; the 1999 sanctuary notification described above is directly referenced in an official Government of India document. Sansad

That distinction helps you write accurately without overclaiming.

## What you can say (accurately) about what you’ll experience there

If you’re crafting this for RealJourneyTravels.com readers, the most defensible on-the-ground framing is experiential-but-grounded:

– Kolleru is a shallow wetland in a delta landscape, so views are typically wide, low-horizon, and sky-dominant—more “open water and reedbeds” than dramatic shorelines. (This is a general descriptive statement about shallow delta wetlands; it’s not a numeric claim.) Britannica
– Water extent is seasonally variable, with monsoon-linked expansion noted by Britannica. Britannica
– Its international wetland status (Ramsar) signals ecological significance beyond casual sightseeing. Sites Information Service

## Conservation context you can’t responsibly ignore

Kolleru’s name comes up frequently in discussions about wetland pressure and management. A travel guide doesn’t need to litigate every detail, but it does need to acknowledge that protected wetlands in production landscapes face real constraints.

From an environmental journalism source, Down To Earth notes Kolleru’s sanctuary status under the Wildlife Protection Act, its 308 sq km area, and its Ramsar designation in 2002. To Earth (This overlaps with the official parliamentary document on the sanctuary notification, which is why I’m comfortable mentioning the same core facts.) Sansad

Outdated-data flag (important):
Some sources you’ll find online cite older interventions, counts, or “current status” snapshots. Those can become stale quickly at wetlands influenced by policy, seasonal hydrology, and land use. If you’re adding specifics like “recent bird counts,” “new management authority,” or “latest restoration phase,” those claims should be updated with a dated official release or current reporting before publication.

## Practical, factual wrap-up

Kolleru Lake is one of the rare places where you can write a travel piece that’s also a straight-up wetlands explainer—because the most interesting “attraction” here is the system itself: a shallow, seasonally expanding delta wetland recognized by Ramsar (2002) and partially notified as a wildlife sanctuary by Andhra Pradesh (1999; 308 sq km), with proximity to Eluru anchoring the geography for trip planning.
