Phewa Lake has lost nearly half its surface in a single lifetime — the 1,119 hectares measured in 1957 had fallen to 572 by 2021, and it is still shrinking. Even so, it remains the mirror that made Pokhara famous: on a windless morning the water returns the whole Annapurna range, crowned by the fish-tail summit of Machhapuchhre, so cleanly that the peaks seem to stand below the surface as well as above it. The lake fills part of a valley that geologists trace to catastrophe — vast debris flows that once swept down the Seti River and dammed the basin, leaving the freshwater lake that now sits at 742 metres. Near its centre, on the only island, the two-tiered Tal Barahi Temple rises above the water, reached by the wooden boats that crowd the shore. The force behind the shrinking is sediment: more than 140,000 tonnes wash off the degraded hills each year and settle on the lakebed.
Most visitors meet the lake from Lakeside, the café-lined strip where painted rowing boats in orange, blue and yellow set out toward the temple. Come at dawn, when the surface lies dead still and the boats glide silently between the mountain reflections; by evening the water turns molten orange as the sun drops behind the ridges. Overhead, paragliders drift down from Sarangkot hill, which has made Pokhara one of the world's busiest launch sites, to land on the shore minutes later. In 2021 the lake and its neighbours were named a Ramsar wetland of international importance, and in 2026 the city began pulling down hotels and walls built illegally inside the lake's protected buffer, though the drive soon stalled in disputes over the boundary. It is a working lake as much as a scenic one — boatmen still fish it, and life jackets are now required after years of drownings.
