Phewa Lake or Phewa Tal (Nepali: फेवा ताल, [ˈpʰewa tal]) is a freshwater lake in Nepal formerly called Baidam Tal located in the south of the Pokhara Valley that includes Pokhara city and parts of Sarangkot and Kaskikot. [1] It is the third largest lake in Nepal and the largest in Gandaki Province after the Phoksundo lake in comparison to Nepal's water bodies.[2] It is the most popular and most visited lake in Nepal. Phewa lake is located at an altitude of 742 m (2,434 ft) and covers an area of about 5.7 km2 (2.2 sq mi).[3] It has an average depth of about 8.6 m (28 ft) and a maximum depth of 24 m (79 ft).[4] The maximum water capacity of the lake is approximately 43,000,000 cubic metres (35,000 acre⋅ft).[5] The Annapurna range[citation needed] on the north is only about 28 km (linear distance) away[6] from the lake. The lake is also famous for the reflection of Mount Machhapuchhre and other mountain peaks of the Annapurna and Dhaulagiri ranges on its surface.[7] The Tal Barahi Temple[citation needed] is situated on an island in the lake.[8] It is located 4 km from the city's centre Chipledhunga.

It lies on the southern edge of city, with the extending along its northern shore, facilitating close integration with local infrastructure and tourism hubs. The lake is nestled in a subtropical valley surrounded by lush hills and offers panoramic views of the Himalayan ranges, including the and massifs to the north. This positioning enhances its scenic appeal, with the valley's topography providing a sheltered environment amid the mid-hills of western . Phewa Lake covers a surface area of 4.53 km² (as of circa ) and drains a of approximately 120 km², making it the second-largest lake in by surface extent. The lake is readily accessible via major roads connecting to , including the and local routes from the city center, allowing easy reach by vehicle or foot from nearby accommodations and transport hubs.

Physical Characteristics

Phewa Lake measures approximately 4 km in maximum length and 2 km in maximum width, giving it a surface area of about 4.5 km². The lake's depth profile features an average depth of 11.7 m and a maximum depth of 23.3 m, contributing to a total volume of roughly 43 million cubic meters. The lake exhibits a roughly shape with an irregular shoreline extending about 18 km, enclosing a small central known as Tal Barahi. As a freshwater body, it maintains clear, reflective waters characterized by low levels averaging around 4 NTU, which enhances its visual clarity. Situated in a subtropical climate, Phewa Lake experiences seasonal water level variations, rising during the monsoon period from May to and receding in the , with an annual fluctuation range of approximately 1 m. This regime influences the lake's thermal stratification, rendering it warm monomictic with a single winter turnover and stable layering from to .

Hydrology and Origin

Geological Formation

Phewa Lake is situated within the , a fault-block basin in the Lesser Himalayas formed through tectonic processes associated with the ongoing collision between the Indian and Eurasian plates. This valley setting, characterized by extensional faulting and uplift during the Pleistocene epoch, provided the structural framework for the lake's basin, with no direct volcanic activity involved in its creation. The basin's development was influenced by regional tectonic uplift that elevated the surrounding terrain, creating a depression conducive to sediment accumulation and water retention. The lake originated as a post-glacial feature around 15,000–14,000 years ago (approximately 13,000 BC), during the deglaciation period following the . Glacial meltwater deposition, combined with a major rock collapse event in the region triggered by an extensional and permafrost thawing, led to massive debris flows that dammed the valley. These ancient landslides, rather than glacial moraines, primarily created the natural barrier for the lake basin, with sediments from the Ghachok Formation—consolidated debris flows derived from the Tethys Himalayan Sequence—forming the foundational dam. The Phewa Formation, consisting of silty and clayey lacustrine deposits, subsequently accumulated atop this, marking the onset of the lake's existence, with of sediments confirming ages from 15,000 to 10,000 years . Over millennia, the lake has undergone evolutionary changes driven by gradual from upstream sources, resulting in progressive shallowing of the basin. This ongoing infilling, evident in the preservation of tree trunks submerged to depths of up to 6 meters, underscores the lake's relatively young geological age and its dynamic response to post-glacial sediment dynamics. Unlike broader paleo-lakes that once filled the entire , Phewa Lake represents a marginal, sediment-dammed feature that has persisted without significant tectonic reconfiguration of the basin itself.

Water Sources and Balance

Phewa Lake receives its water primarily from surrounding streams and direct rainfall, with the main perennial inflow consisting of the Harpan Khola, supplemented by several temporary streams such as the Phirke Khola, Andheri Khola, Sidhane Khola, and Phusre Khola. The Harpan Khola serves as the dominant contributor, delivering an annual mean inflow of approximately 9.2 cubic meters per second, while the overall catchment receives substantial during the season from June to September, accounting for the majority of the lake's annual input. These sources maintain the lake's hydrological regime, though urban development in the watershed has intensified and through these channels. The lake's outflow occurs via the Phewa River at its southern end, where water is discharged through the Phewa Dam, constructed in to regulate flow. This 21-meter-high structure controls flooding, facilitates for surrounding farmlands, and supports small-scale generation, fundamentally altering the natural by stabilizing levels and reducing seasonal extremes. The dam enables a storage capacity of about 46 million cubic meters, with outflows managed through two canals that divert water for downstream uses. In 2021, maintenance work on the dam temporarily lowered lake levels, highlighting ongoing management needs. Overall, the water balance reflects a dynamic equilibrium influenced by inflows, , seepage, and regulated outflows, resulting in seasonal fluctuations of up to 2–3 meters in , primarily driven by recharge and dry-season withdrawals. Annual inflow volumes support this variability, though exact totals vary with ; and seepage represent notable losses in the subtropical climate. from inflows has gradually reduced the lake's storage capacity over decades. The lake's water quality is mesotrophic, having transitioned from oligotrophic conditions in the 1970s due to increasing levels from agricultural and carrying pollutants into the inflows, but is increasingly impacted by these sources. Typical pH values range from 7.5 to 8.3, with surface waters often slightly alkaline due to carbonate influences from dilution and geological inputs.

Ecology

Biodiversity

Phewa Lake supports a diverse array of aquatic life, with approximately 21 fish species recorded across six families and 16 genera, predominantly Cyprinidae. Endemic species include the snow trout (Schizothorax richardsonii), a cold-water cyprinid native to Himalayan foothills, alongside other native cyprinids such as Tor putitora (sahor) and Barilius bendelisis. Introduced species, notably common carp (Cyprinus carpio), have been stocked since the 1970s to bolster fisheries, contributing significantly to the lake's fish biomass. The lake's avifauna is rich, with over 140 bird species documented in the surrounding wetland, including a notable assemblage of waterbirds. Migratory waterbirds such as egrets (Egretta spp.), herons (Ardea spp.), and kingfishers (Alcedo atthis) frequent the area, with seasonal peaks during winter months when populations swell due to influxes from higher altitudes and Siberia. Resident species like the lesser adjutant (Leptoptilos javanicus) and winter visitors including the Eurasian wigeon (Mareca penelope) enhance the ecological diversity, supporting a dynamic food web. Vegetation in and around Phewa Lake forms distinct aquatic and riparian communities essential for habitat stability. Submerged macrophytes, such as and , dominate the littoral zones, providing oxygen and shelter for aquatic organisms. Emergent reeds like spp. line the shorelines, acting as buffers against , while surrounding forests feature sal (), a dominant tree in the subtropical broadleaf ecosystems of the . Invertebrate communities underpin the lake's food chain, exhibiting high diversity among zooplankton and benthic organisms. Zooplankton assemblages, including rotifers, cladocerans, and copepods, show bimodal density peaks in November and January, with dominant taxa like Moina micrura and Bosmina longirostris reflecting seasonal nutrient dynamics. Benthic macroinvertebrates, such as chironomid larvae and oligochaetes, thrive in the sediments, serving as primary food sources for fish and birds, with overall diversity indicating mesotrophic to eutrophic conditions. As part of the Phewa Lake wetland complex and the Ramsar-designated Lake Cluster of since 2016, the holds significant conservation value due to its and hydrological importance. The area indirectly supports regional through connectivity to broader river systems.

Environmental Challenges and Conservation

Phewa Lake faces significant environmental threats from , primarily caused by in its watershed due to , , and road construction, with an estimated annual influx of 175,000 to 225,000 cubic meters. This has contributed to a reduction in lake depth and a loss of surface area, from 4.61 square kilometers in 1961 to 4.02 square kilometers in 2018 (as of 2018), with the water area further reduced to 3.96 square kilometers in 2024. from urban stormwater runoff, untreated , and tourism-related waste, including plastics and boat fuels, has exacerbated and algal blooms, while shoreline encroachment through illegal constructions has resulted in further area reduction, driven by rapid urbanization around . These pressures have diminished , with increased limiting visibility to around 40 centimeters and elevating levels of contaminants like averaging 1.51–2.96 particles per liter in (as of 2021–2022). Climate change intensifies these challenges by altering patterns, leading to more erratic rainfall, prolonged droughts, and intensified floods that accelerate and into the lake. Surface water temperatures have increased by 1.1–1.8 °C from 1993 to 2018, contributing to seasonal reductions in dissolved oxygen levels to as low as 4–6 milligrams per liter during summers, stressing aquatic life and promoting like water hyacinth. Without mitigation, projections indicate the lake could lose up to 80% of its storage capacity within the next 110 to 347 years, severely impacting its ecosystem services. Conservation efforts began with the 1997 IUCN , which outlined integrated strategies to curb and through and . Community-based programs, led by Nepal's Department of National Parks and Wildlife Conservation, involve local cooperatives in weed removal, silt trapping, and bioengineering initiatives like plantations in the 2010s. and restoration projects, supported by the Metropolitan City, have included the construction of dams and enforcement, with over 270 illegal structures removed by 2023 following directives. In May 2025, authorities installed digital boundary poles to demarcate and protect the lake's perimeter. Under Nepal's National Wetlands Policy of 2012 and the designation of the Lake Cluster of —including Phewa—as a Ramsar protected in 2016, the lake benefits from a legal framework emphasizing monitoring and sustainable use. Municipality conducts regular assessments and enforces a 65-meter shoreline buffer to prevent further encroachment. International aid from organizations like WWF-Nepal and USAID has funded boards and micro-basin planning, though challenges in implementation persist due to governance gaps. Ongoing initiatives aim to avert the projected loss of storage capacity through enhanced and regulatory enforcement.
