Waterbody & Drainage Proximity
Is the plot on or near a lake, tank or river? The nearest mapped waterbody and its distance, anywhere in India — and in Telangana, whether that tank is live or a lost, encroached bed.
What this tool tells you
A plot on or beside a tank, lake, river bed or storm-water nala is one of the sharpest hidden risks in Indian land: waterbodies and drains carry a legally protected buffer, and a tank that reads as dry land today may still be a waterbody on the revenue record.
Straight-line distance to the nearest mapped waterbody edge, from the all-India NRSC land-use layer. On water means the plot sits on mapped water — the FTL bed, and the serious case.
The waterbody class — lake or pond, reservoir or tank, river or stream, canal or drain — and, in Telangana, its name, area and water quality from the NWIC inventory.
Distance to the nearest storm-water nala or canal-drain. Building on a nala, or inside its buffer, is a top urban-flooding and demolition risk regardless of where the nearest lake is.
Where the state publishes it, whether the nearest tank is live or a lost, encroached bed — with its survey number, so you can check it against the record yourself.
How to read the result
A proximity tool: the distance is reported as a fact, and only one condition is graded as a defect.
On water is the flag; near water is a prompt
A plot on mapped water is the FTL bed and reads as severe. Everything else is informational — lakeside land is routinely and legally developed.
The mapped extent is smaller than the FTL
The legal Full Tank Level usually sits outside the mapped water. A comfortable distance here is not a clearance; it is a reason to go and check the demarcation.
A blank Telangana block means no record, not no risk
Outside Telangana the tank and encroachment rows are absent because nothing is published, not because the bed is clear.
Methodology and data sources
All-India base layer
Distance, type and extent come from the NRSC (ISRO) Bhuvan SISDP land-use layer — the same authoritative water layer the flood and terrain checks use, so the three tools cannot disagree about where the water is.
Telangana enrichment
Cross-checked against the NWIC / SAC waterbody inventory (name, class, area, turbidity, aquatic vegetation), the Telangana Tank Information System (survey number, and whether the tank is live or lost) and the HMDA / ORR register (encroachment status, bund height, capacity).
Drainage network
Storm-water nalas (GHMC) and canal-drains (Telangana), reported as a separate distance with its own encroachment flag, because a drain is a separate authority and a separate risk from the waterbody itself.
What this is not
Not a legal determination. Proximity and any buffer are estimates from mapped extents, not the official FTL demarcation. Verify the FTL and the survey record with the state authority before you transact or build.
