Nainital Lake, a natural freshwater body, situated amidst the township of Nainital in Uttarakhand State of India, tectonic in origin, is kidney shaped or crescent shaped and has an outfall at the southeastern end.
Nainital is most popular hill station of Kumaon district. It is famous for its Naini Lake located at the centre of the town and several other lakes of nearby areas.
Nainital Lake, in the Nainital district called the Lake District of India, is one of the four Lakes of Kumaon hills; the other three lakes are the Sattal Lake, the Bhimtal Lake and the Naukuchiyatal Lake.

Historical records confirm that in 1839, Mr. P. Barron, who is supposed to be the first one who visited Nainital, from Rosa, an English business man in sugar trade, on a expedition accidentally coming across the lake at Nainital was so captivated that he decided to build a European Colony on shores of the lake. The news magazine, the Englishman Calcutta, reported in 1841 discovery of this lake near Almora. It is believed that two Indian sages visited there, wandering, it is a belief of people that they blessed the lake with divine power, one can acquire divinement by taking bathe in it, and the same as in the Mansarovar lake.
The lake is bounded by the high and steep Naina peak on the North West side, by the Tiffin Top to the south west side and snow view peaks on the north. Coniferous forest trees cover these hill ranges. The annual rainfall in the basin area of the lake is reported to be 1294.5 mm (43.15 inches). Tropical monsoon climate with maximum temperature 24.6 °C and minimum of 0.5 °C are recorded. The water is reported to be alkaline in nature (ph value of 8.4–9.3).
The lake receives flows from the surrounding catchment basin which comprises the hill slopes and springs. The hydrologic studies related to water balance and sedimentation was done using radioisotopes for estimating/measuring the various components of the inflow and outflow into the lake. Studies indicated that the subsurface inflow and outflow were significant – ranging from 43 to 63% and 41 to 54%, respectively, of the total inflow and outflow, except in years of exceptionally heavy rainfall. The components of outflows were the surface outflow, the subsurface outflow through the springs on the downstream side and draft through wells for meeting the water supply of Nainital town and evaporation loss from the lake surface. The mean water retention time for the lake was computed as 1.16 years for the mean annual rainfall.
The Krol group of rocks, comprising slates, marls, sandstones, limestones and dolomites with a few small dykes intrusives, is the dominant geological formation of the lake’s surroundings. The lake is deduced to have been formed tectonically. Balia Nala, which is the main stream feeding the lake is along a fault line and the subsequent streams align parallel to major joints and faults. 26 major drains feed the lake including the 3 perennial drains. The lake catchment has highly folded and faulted rocks due to poly phase deformation. Landslides are a frequent occurrence in the hill slopes surrounding the lake, which are steep. The slopes are highly vulnerable to landslides and mass movement due to various geological and human factors. Several landslides have occurred in the past (pictured) around the lake. Many settlements around the lake are located in landslide areas.
While the Nainital district where the lake is situated (in the middle Himalayan ranges up to 2,000 m (6,600 ft), a temperate zone), is rich in flora (typical temperate climate plants) and fauna, the details of the flora and fauna specific to the lake and its surroundings recorded are the following.
The trees and bushes grown in the region (lake’s basin) with their botanical and common Indian names (in parenthesis) are reported to be: a) Quercus incana Oak (Banj); b) Aesculus indica (Pangar or Horse chestnuts); c) Juglans regia (Akhrot or walnut), d) Populus ciliata (Hill Pipal, a sacred tree); e) Fraxinus micrantha (Ash tree or Angu); f) Platanus orientalis (Chinar); g) Rubus lasiocarpus (Hisalu); h) Rosa moschata (Kunj or Musk rose); i) Berberis asiatica (Kilmora);j) Cupressus torulosa (Surai or Himalayan cypress); k) Rhododendron arboreum (Buruns); Cedrus deodara (Deodar); l) Salix acmophylla (Weeping Willow); and m) Pinus (Pine).
Several species of medicinal flora and horticulture plants have also been reported.
The fishes found in the lake are generally carps Mahseer, (the Hindi name of mahāsir, mahāser, or mahāsaulā used for a number of fishes of the group), also hill trout and the mirror carp which breed several times during one spawning season during May to September. Two species of Mahaseer fish viz., Tor tor: The red finned mahseer and the Tor putitora: The yellow finned mahseer, a food fish which grows to varying sizes from 20 to 60 cm (7.87 to 23.62 inches) are reported. The three species of Hill Trout found in the lake are the Schizothorax sinuatus, Schizothorax richardsoni and Schizothorax plagiostornus. The imported fish bred in the lake is Mirror carp or Cyprinus carpio. Gambusia affinis also called Mosquitofish has been introduced in the lake as a biocontrol measure to control Mosquito larvae.
Nine species of birds and nine species of animals have been recorded in the Nainital district.
A scientific study indicates that the open drains feeding the lake introduce toxic substances from the catchment of the lake, particularly heavy metals which get adsorbed onto the suspended sediments, which in turn settle down in the bottom of the lake. A study of the risk assessment code has revealed that 4–13% of manganese, 4–8% of copper, 17–24% of nickel, 3–5% of chromium, 13–26% of lead, 14–23% of cadmium and 2–3% of zinc exist in exchangeable fraction which puts the lake under the low to medium risk category and infers that it could enter into food chain and also cause deleterious effects to aquatic life. This study provides the basic database to formulate guidelines for the dredging operations and/or restoration programmes in the lake.
The water quality studies carried out by the National Institute of Hydrology during 1999–2001 on physico-chemical parameters (pH, temperature profile, Secchi’s transparency, dissolved oxygen, BOD, COD and nutrients), biological profile (density of population, biomass and species diversity of phyto, zooplankton and macrobenthos) and bacteriological characteristics have led to the conclusion that long-term limnological changes have occurred in the lake. Excess of nutrients inflow have contributed to the eutrophic conditions and the internal recycling of nutrients from sediments during water circulation has resulted in luxurious growth of phytoplankton. The lake is thus anoxic and has reduced hypolimnion, winter circulation, large phytoplankton and relatively lower animal population.
The problems facing the lake which were also listed in the plea in a Public Interest Litigation (PIL) before the Supreme Court of India in 1995 seeking court directive for redress measures could be summarised as below:
The National Institute of Hydrology (NIH) of Roorkee who prepared a plan for the restoration of the lake, at an estimated cost of Rs 50 crore (about US $10 million), sponsored by the Ministry of Environment and Forests, Government of India, are also now guiding the restoration measures. The Conservation and Management Plan evolved by NIH is not only lake centric but also proposes to tackle the immediate periphery of the lake which contributes an adverse impact on the lake. The "Nainital Jheel Parikshetra Vishesh Kshetra Vikas Pradhikaran", the Lake Development Authority notified under U.P. Special Area Development Act 1986 is a Special Purpose Vehicle (SPV) set up for implementing the restoration works. The restoration works that have been implemented or are in different stages of implementation are the following:
The Honourable Supreme Court of India in its judgment of 1995, in response to the Public Interest Litigation, gave the following recommendations which have also been addressed in the restoration measures mentioned above.
(i)Sewage water has to be prevented at any cost from entering the lake; (ii) So far as the drains which ultimately fall in the lake are concerned, it has to be seen that building materials are not allowed to be heaped on the drains to prevent siltation of the lake;(iii) Care has been taken to see that horse dung does not reach the lake. If for this purpose the horse stand has to be shifted somewhere, the same would be done. The authorities would examine whether trotting of horses around the lake is also required to be prevented;(iv) Multi-storeyed group housing and commercial complexes have to be banned in the town area of Naini Tal. Building of small residential houses on flat areas could, however, be permitted;(v) The offence of illegal felling of trees is required to be made cognizable.(vi) Vehicular traffic on the Mall has to be reduced. Heavy vehicles may not be permitted to ply on Mall;(vii) The fragile nature of Ballia Ravine has to be taken care of. The cracks in the revetment of Ballia Nullah have to be repaired urgently.
In the "India Today" magazine, Prasanta Rajan, a journalist, in a preamble to the particular interest shown by the Lady District Magistrate of Nainital in restoration works of the lake has very vividly described the lake in these words:
Look for the lake through the colonial windows of Pant House, a vintage English bungalow on the hilltop, now submerged in wintry night, solitary with a kind of Wuthering Heights mystery. Down below, the lake is a laminated stillness, protected by seven never-sleeping hills. In the dead darkness of Kumaon, this magnificence is a distant, partially lit vision, less than real, as the hills of frozen memories make the lake a footnote in water.
There is the Nainital Boat Club that offers yachting facilities at the lake, where a fleet of Half Raters, designed by Linton Hope, sails.. The Annual Kingfisher Yachting Competition (Regatta) is held here in the third week of June. The Kumaon festival which brings out the local cultures and traditions is organized every year during the winter months of October and November, by the Tourism Department.
Chaukhutia is a town in Almora district of Uttarakhand. It is located on the bank of the river Ramganga, and derives its name from a Kumaoni word "Chau-khut" which means four feet. In Chaukhutia's context, 'four feet' means four ways or directions. The first way is towards Ramnagar, second towards Karanprayag, third towards Ranikhet and Almora and the fourth way is towards Tadagtaal, Kheera.
A group of small temples dating back to 9th century AD were found in Chaukhutia, during an excavation in 2016-17. The temples, according to traditions of the architecture, were constructed around 9000 years ago. Some of the temples didn't have roofs, but shivalingas inside the temples were still intact. These temples were considered to be a part of a large group of temples that were buried, perhaps, by debris of landslide long back.Gurney House
Gurney House is a historic building located in Nainital, Uttarakhand, India, and was the residence of hunter-conservationist and writer Jim Corbett. It is located near Nainital Lake, and was built in 1881. Miss Margaret Winifred Corbett, Jim Corbett's sister, sold the house to Mr. Sharda Prasad Varma in the year 1947 when they left for Kenya. Currently the house is owned by his granddaughter, Nilanjana Dalmia. The cottage was constructed in 1880 with the dismantled material of their earlier house on Alma Hill (which was on the hill on which a landslide occurred). And hence the name implying a house built of carted material of a dismantled house.Kumaon division
Kumaon or Kumaun is one of the two regions and administrative divisions of the Indian state of Uttarakhand, the other being Garhwal. It includes the districts of Almora, Bageshwar, Champawat, Nainital, Pithoragarh, and Udham Singh Nagar. It is bounded on the north by Tibet, on the east by Nepal, on the south by the state of Uttar Pradesh, and on the west by the Garhwal region. The people of Kumaon are known as Kumaonis and speak the Kumaoni language.
Historically ruled by the kings of Katyuri and Chand Dynasties, the Kumaon division was formed in 1816, when the British reclaimed this region from the Gorkhas, who had annexed the erstwhile Kingdom of Kumaon in 1790. The division initially consisted of three districts, Kumaon, Terai and Garhwal, and formed the northernmost frontier of the Ceded and Conquered Provinces in British India, that later became North Western Provinces in 1836, United Provinces of Agra and Oudh in 1902, and United Provinces in 1937.
It is home to a famous Indian Army regiment, the Kumaon Regiment.
Important towns of Kumaon are Haldwani, Nainital, Almora, Pithoragarh, Rudrapur, Kichha, Kashipur, Pantnagar, Mukteshwar and Ranikhet. Nainital is the administrative centre of Kumaon Division and this is where the Uttarakhand high court is located.Lake retention time
Lake retention time (also called the residence time of lake water, or the water age or flushing time) is a calculated quantity expressing the mean time that water (or some dissolved substance) spends in a particular lake. At its simplest, this figure is the result of dividing the lake volume by the flow in or out of the lake. It roughly expresses the amount of time taken for a substance introduced into a lake to flow out of it again. The retention time is especially important where pollutants are concerned.Lakes of Kumaon hills
Lakes of Kumaon hills are in Uttarakhand state, called the ‘Lake District’ of India. These are under restoration with funds provided by the National Lake Conservation Plan (NLCP) of the Government of India. The lakes are the following.
Sat Tal Lake, Sattal
NaukuchiatalList of hill stations in India
The hill stations are high-altitude towns used especially by European colonialists, as a place of refuge to escape the blistering summer heat and dust of plains during the British Raj. They are prevalent in Southeast Asia and the Indian subcontinent, particularly in India.
The Indian subcontinent has seven principal mountain ranges and the largest of all is the Himalayas that lies in the northern part of India. The famous peaks and ranges include the Kangchenjunga range in the Eastern Himalayas which frames the hill stations of Darjeeling and Gangtok as well as the Nanda Devi in Uttarakhand. The Shivalik range that also lies within the same region also has some famous hill stations that include Dalhousie, Kullu, Shimla, Nanital sahyadri and many more.Most of the hill stations in India were developed by the British around a central mall to get respite from the oppressive summer heat. Many have picturesque lakes as their focal point, making them excellent places for boating activities.
Most of the hill stations in India are located in Jammu and Kashmir, Himachal Pradesh, Uttarakhand, Sikkim, West Bengal, Arunachal Pradesh, Nagaland and Meghalaya in the Himalayas and in Maharashtra, Karnataka, Tamil Nadu and Kerala in Western ghats. Some are located in Eastern ghats Andhra Pradesh, Odisha. Some of the hill stations in India are listed below by state.
Since a number of these hill stations attract large number of tourists in summer as well as other times of the year,they are well connected by rail, road and air services to major Indian cities.List of lakes

This is a list of notable lakes in India.Nainital
Nainital (pronunciation ), also known as Naini Tal, is a popular hill station in the Indian state of Uttarakhand and headquarters of Nainital district in the Kumaon foothills of the outer Himalayas. Situated at an altitude of 2,084 metres (6,837 ft) above sea level, Nainital is set in a valley containing an eye-shaped lake, approximately two miles in circumference, and surrounded by mountains, of which the highest are Naina (2,615 m (8,579 ft)) on the north, Deopatha (2,438 m (7,999 ft)) on the west, and Ayarpatha (2,278 m (7,474 ft)) on the south. From the tops of the higher peaks, "magnificent views can be obtained of the vast plain to the south, or of the mass of tangled ridges lying north, bound by the great snowy range which forms the central axis of the Himalayas."Nainital district
Nainital district is a district of Uttarakhand state, India. The headquarters is at Nainital.
Nainital District is located in Kumaon Division, and is bounded on the north by the Almora District and on the south by the Udham Singh Nagar District. Haldwani is the largest town in the district.Sherwood College
Sherwood College is a co-educational residential school in Nainital, Uttarakhand, India, established in 1869.Tso Moriri
Tso Moriri or Lake Moriri (Tibetan: ལྷ་མོའི་བླ་མཚོ, Wylie: lha mo bla mtsho) or "Mountain Lake", is a lake in the Ladakhi part of the Changthang Plateau (literally: northern plains) in Jammu and Kashmir in Northern India. The lake and surrounding area are protected as the Tso Moriri Wetland Conservation Reserve.
The lake is at an altitude of 4,522 m (14,836 ft). It is the largest of the high altitude lakes entirely within India and entirely within Ladakh in this Trans-Himalayan biogeographic region. It is about 16 miles (26 km) north to south in length and two to three miles (3 to 5 km) wide. The lake has no outlet at present and the water is brackish though not very perceptible to taste.
The lake is fed by springs and snow-melt from the adjacent mountains. Most water enters the lake in two major stream systems, one entering the lake from the north, the other from the southwest. Both stream systems include extensive marshes where they enter the lake. It formerly had an outlet to the south, but this has become blocked and the lake has become a endorheic lake. The lake is oligotrophic in nature, and its waters are alkaline.
Accessibility to the lake is largely limited to summer season, though Karzok on the northwest shore and the military facilities on the eastern shores have year-round habitation.
