Nepal / lakes & downstream rivers

Explore Nepal’s lakes & rivers

Inspect a glacial lake, follow river connections, and explore infrastructure context.

Glacial lakes

Glacial Lake Observatory v1.02 · Sentinel-2 · 2017–2024

Glacial-lake controls require the interactive map.

Show GLO unique lakes

Points are published GLO centroids. Circle size uses the source dissolved maximum mapped extent across 2017–2024; it is not a 2026 lake-area measurement.

Search lakesLake record

Select a GLO record to inspect mapped extent, source connectivity, basin, elevation and change statistics without implying hazard status.

Boundary levels

Country Provinces Districts Local levels and special areas

Districts appear from zoom 6; local levels from zoom 8. Orange areas are protected or special-area pieces in the source.

Terrain

Copernicus GLO-90 · surface elevation

Asia overview: Mapzen terrain. Nepal elevation inspection: Copernicus GLO-90. Zoom out to explore the surrounding region.

Terrain controls require the interactive map.

Hillshade 3D terrainVertical exaggeration: 1×

Hillshade and 3D are derived views. Exaggeration changes appearance only. Includes vegetation and buildings. Finest display pixels are about 270 m here; zooming closer adds no detail.

Choose coordinates or click the map to inspect elevation.

Rivers

FAO Rivers 2026 / HydroRIVERS · connected reach IDs

River controls require the interactive map.

Show river network

Primary and mid-order reaches appear first; headwater/minor reaches load from zoom 6.5. Click a river line on the map to select it, then trace downstream.

Find a river or reachRiver or reach

The source does not provide river names for these reaches. Reaches are identified by stable HYRIV_ID values; named places come from GeoNames points.

Select a reach to inspect its topology, source measurements and stable downstream linkage.

Downstream trace

Follow connected river reaches from the selected HYRIV record.

Network connectivity only. This does not show flooding, travel time or confirmed exposure.

Tracing needs both river partitions. Load or retry the river network above.

Select a river reach above or click a river on the map.

Glacier and lake outlets: UNKNOWN in the current inventories. Settlements, infrastructure and population intersections await their source layers and the exposure feature.

Lake outburst modelling

Select a lake above to identify the modelling subject.

Flood extent and damage: UNAVAILABLE.

A lake point or a downstream river line cannot identify inundated places or destroyed assets. This inventory has no verified lake outlet-to-river connection, breach parameters or validated hydraulic model.

Physical GLOF project: scope, required inputs and validation

Use river tracing for connectivity only. Infrastructure is geographic context, not a list of affected assets.

Educational river simulation

Infrastructure context

Load roads, bridges, facilities and hydropower only when needed. Coverage is incomplete; proximity is not damage.

COD-AB v02 · click a boundary to inspect it

Map key

Every layer also has a text description in its panel. Shape and text distinguish layers; colour is a second cue.
