'''Fateh Sagar Lake''' is situated in the city of [[Udaipur]] in the [[India]]n state of [[Rajasthan]]. It is an artificial lake named after [[Maharana]] [[Fateh Singh of Udaipur and Mewar]], constructed north-west of Udaipur, to the north of [[Lake Pichola]] in the 1680s.

It is one of the four lakes of the [[Udaipur]] city; the other three being: the [[Lake Pichola]] (within the Udaipur town), Udai Sagar Lake, {{convert|13|km}} to the east of Udaipur, and [[Dhebar Lake]] or Jaisamand Lake, {{convert|abbr=on|52|km}} south east of Udaipur.<ref name=lakes>{{cite web |url=http://udaipur.nic.in/lake.htm |title=Lakes |url-status=dead |archive-url=https://web.archive.org/web/20130327004855/http://udaipur.nic.in/lake.htm |archive-date=27 March 2013 }}</ref><ref name=r1>"[http://www.amazingudaipur.com/lakes%20of%20udaipur.html Udaipur Lakes, Lakes Udaipur, Lakes Of Udaipur, Pichhola lake, Fatahsagar Lake, Udaisagar Lake, Lake Pichola, Badi Lake, Rajsamand Lake] {{webarchive|url=https://web.archive.org/web/20090106143612/http://www.amazingudaipur.com/lakes%20of%20udaipur.html |date=6 January 2009 }}". ''www.amazingudaipur.com''.</ref>

Within the confines of the Fatah Sagar Lake, there are three small islands; the largest of these is the Nehru Park ({{convert|abbr=on|4|km2}} area), which is a popular tourist attraction, the second island ({{convert|abbr=on|0.06|km2|acre|disp=or}} area) houses a public park with an impressive water-jet fountain, and the third island (1.2 km<sup>2</sup> area) is the address for the [[Udaipur Solar Observatory]] (USO). The Nehru park is accessible by inboard motor boats. The blue waters of the lake and the backdrop of the green mountains has given the soubriquet "the second Kashmir" to Udaipur .<ref name=lakes/>

Udaipur Lake Conservation Society's reports indicate that the lake supports and sustains ground water recharge, drinking water, agricultural use, industrial use, ecological water availability and provides employment to 60% population of Udaipur.

== History ==
[[File:Lake Fatehsagar.jpg|thumb|Sunset over the lake]]
[[File:Shivalal. Maharana Fateh Singh's hunting party crossing a river in a flood Udaipur, Mewar, 1893, City Palace Museum, Udaipur..jpg|thumb|Maharana Fateh Singh's hunting party in Udaipur]]
In 1687, [[Maharana]] Jai Singh first constructed the lake but two hundred years later the earthen bund which formed the lake was washed away during floods, and thereafter [[Maharana]] [[Fateh Singh, Maharana of Udaipur and Mewar|Fateh Singh]], in 1889, built the "Connaught Dam" on Lake Dewali to mark the visit of Duke of Connaught, son of Queen Victoria. The dam enlarged the lake, and it was later renamed, Fateh Sagar Lake.<ref name=lakes/>

== Hydrology and structures ==
The runoff emerging from surrounding hills drains into this lake. The lake is pear-shaped and is encircled by the [[Aravalli hills]] on three sides with a straight gravity stone masonry dam on the eastern side which has a spillway to discharge flood flows during the monsoon season.<ref name="Fatah">{{cite web|work=Team Rajasthan travels guide |url=http://www.rajasthantravelsguide.com/rajasthan-tourism/udaipur-tourism/lakes-in-udaipur/fateh-sagar-lake.html |archive-url=https://web.archive.org/web/20190412082216/http://www.rajasthantravelsguide.com/rajasthan-tourism/udaipur-tourism/lakes-in-udaipur/fateh-sagar-lake.html |url-status=dead |archive-date=12 April 2019 |title=Fateh Sagar Lake |publisher=Rajasthantravelsguide.com |access-date=28 July 2010 }}</ref>

Three causeways, one from Pichola Lake, the other from Madar Lake and the third one from Badi Lake lead to the Fateh Sagar Lake. There are three inlet channels, which feed the lake and an overflow section on the eastern side in the masonry dam of {{convert|800|m}} length. [[Monsoon]] rains are the main source of all water to the lake. Initially constructed as an irrigation scheme, it is now the second major source of drinking water to the city of Udaipur and the irrigation supplies have been discontinued. A canal from the [[Rang Sagar Lake]] connects to the Fateh Sagar Lake. A gate controlled canal further connects Fateh Sagar Lake with Lake Pichhola.<ref name="data_base">{{cite web|url=http://www.ilec.or.jp/database/asi/asi-46.html |title=Lake Fateh Sagar |publisher=Ilec.or.jp |access-date=28 July 2010 |url-status=dead |archive-url=https://web.archive.org/web/20110523142816/http://www.ilec.or.jp/database/asi/asi-46.html |archive-date=23 May 2011 }}</ref> The Northeastern embankment is known by three names viz., the Pal, the Drive, or Connaught Bund (bund means embankment).

During drought conditions, when the rainfall is meager, water storage in the lake is insufficient to meet the needs. To prevent loss of water due to evaporation, cetyl alcohol (hexadecanol) is sprayed over the lake surface.<ref name="Fatah" />

== Water quality issues ==
Some of the water quality parameters reported<ref name="data_base"/> relate to:
* pH value, which varies from a maximum of 8.4 on the surface to a minimum of 7.8 at the bottom and with minimum value of 7.9 at {{convert|abbr=on|5|m}} depth
* DO [mg/l] value varies from a maximum of 9.4 on the surface and minimum of 1.2 at the bottom, at 5 m depth the lowest value being 3.3.
* Maximum Nitrogen Concentration (NO3-N [mg/L] ) of 0.941 at 1 m below the surface and 0.523 at the bottom of the lake have been reported.
* The lake water is reported to be [[polymictic]], and there is lack of true [[thermocline]]. Gradient is recorded to be poor, which results in frequent mixing, as experienced in many tropical lakes.
* The lake water temperature varies from a minimum of {{cvt|19|°C}} in January to {{cvt|29.4|°C}} in June at the surface, and correspondingly {{convert|abbr=on|16.8|and|28.5|°C}} at the bottom of the lake.

[[Eutrophication]] has occurred in the lake due to [[algal bloom]]; the dominant species causing this are algae: Microcystis sp and submerged macrophytes. Urbanization around the lake has also degraded water quality, which is a risk to public health of the people who are dependent on the lake for their water supply requirements. [[Siltation]] has caused reduction of storage capacity. Increase in nutrient level is also taking place on account of [[Leaching (agriculture)|leaching]] from agricultural activity in the marginal agricultural lands around the lake periphery. These are some of the reasons attributed for lake degradation.<ref name="data_base"/> The [[Udaipur]] city, set around the lakes, with its numerous hotels catering to the large influx of tourists and a large number of residential complexes on the slopes of the lake, also add pollutants to the lake.<ref name = Jheel/>

== Flora ==
Within the lake water, the [[flora]] recorded consists of the following.

Macrophytes that have merged in the lake, floating macrophytes, the submerged macrophytes and the Phytoplankton.

The Biomass production due to macrophytes is reported to be a maximum of {{convert|864.9|g/m2|abbr=~}} on the surface of the lake, with a minimum of 329 g/m<sup>2</sup> at the bottom. The biomass recorded due to plankton is reported to be at maximum during January, as {{convert|67|mg/L|abbr=~}} at the surface and 23 g/L at the bottom of the lake. It is a low of 16 g/L at the surface and 1 at the bottom during July, during the rainy season.

The lake's surroundings have sparse vegetation cover; however, several species of plants are found along the roads and the hills in the lake basin.

== Fauna ==
The fauna recorded in the lake are the [[Zooplankton]], [[Benthos]] and [[Fish]]. The economically important fishes reported are:<ref name="data_base"/>

''C. punctatus, C. reba, Catla catla, L. calbasu, Channa marulius, Cirrhina mrigala, L. gonius, Labeo rohita, Tor khudree, and Wallago attu.''

== Lake restoration works ==
The first effort to desilt the lake and improve its water quantity was undertaken by local citizen groups and environmental conservation organizations. The shallow part of the lake was desilted through voluntary labour in the early 1970s.<ref name="data_base"/>
Udaipur Lake Conservation Society, a Non Governmental Organization (NGO) set up in 1992, has independently carried out studies of the problems of the lakes of Udaipur and has been continuously pressurizing the government agencies to take up several restoration schemes on the lakes of Udaipur, including Fatah Sagar Lake, some of which are reported to have been acted upon by the Rajasthan Government. The restoration works pursued are Limnological Conservation Works (introducing new varieties of fish species), Ecological Conservation Works (catchment area treatment), Hyacinth removal (through bio-control), lining of unlined canal from [[Moti Magri|Moti Magri Hill]] to Fatah Sagar Lake, construction of sewage lines, institutional development in the form of creating Special Purpose Vehicle (SPV) for the lakes, etc. It has appealed in the Rajasthan High Court, through Public Interest Litigations, seeking court's intervention on several issues concerning restoration of small lakes, land acquisition up to the High Flood Level (HFL) of the Lakes, Constitution of the Lake Development Authority (LDA) for Udaipur Lakes, etc. which are reported to have been upheld by the High Court<ref name = Jheel/>

[[Government of India]], under its National Lake Conservation Plan (NLCP) of the Ministry of Environment & Forests (MoE&F), has sanctioned in June 2008, projects for development of Fatah Sagar Lake in Udaipur at a cost of about US$10 million (Rs 42 crore) with central government sharing 70% of the costs and the balance 30% by the State government. This programme of NLCP envisages desilting of the lake area, installation of a sewage treatment plant, beautification of the adjacent area and installation of fountains, with a completion schedule of 18 months.<ref>{{cite news|url=http://www.hindu.com/2008/06/23/stories/2008062355030900.htm |archive-url=https://web.archive.org/web/20121103055338/http://www.hindu.com/2008/06/23/stories/2008062355030900.htm |url-status=dead |archive-date=3 November 2012 |title=National : Fatah Sagar Lake, Walled City to be beautified |date=23 June 2008 |newspaper=[[The Hindu]] |access-date=28 July 2010}}</ref>

== Access ==
A winding road with a peripheral protection stone wall on the lake side exists on the eastern shore of the lake.<ref name="data_base"/> The entire circumference of the lake could be covered by road via Moti Magri Road, Fatah Sagar Drive, Rani Road and the winding road on the eastern side route to get a picturesque view of the lake, and the [[Aravali]] Hills surrounding it. Tongas (horse driven two wheelers), auto-rickshaws and taxis can be hired to reach the lake as well.<ref name = r1/>

== Festival ==
Every year a festival called the Hariyali Amavasya Mela (Green [[New Moon]] Fair) is organized at the lake precincts, in the month of Shravan (August/September).<ref name = r1/>

== Aquarium ==
[[File:UnderTheSun.jpg|thumb|250px|left|'Under The Sun' Aquarium in Udaipur.]]
Fateh Sagar also houses an aquarium known as 'Under The Sun'.
