The Mansagar lake is a man-made water body. It was initially the Royal Hunting Ground of the Rulers of Amer. The conservation of Mansagar lake is located at Amer road at a distance of about 4 kilometers from the walled city of Jaipur.

On the western side, Amber road bounds this lake; the northern side is Kanak Vrindavan temple and hills of Nahargarh forest; the eastern side is Mansagar Dam and on the southern side is the lake precinct side.

There were several wetlands and marshy land in the area. The worst famine occurred during the reign of Raja Mansingh-I of Amber in 1596 A.D. There were no water miles.

He thus undertook to construct a dam across the eastern valleys between the amber hills and Amargarh hills. The eastern dam was made of mud and Amagarh Quartzite, but when it leaked, at the beginning of the 17TH century it was reinforced with a stone masonry wall. Later on, burjs and tunnels were constructed.

The conservation of the Mansagar lake dam is around 300m long and 28.5m-34.5m wide. There are three sluice gates to regulate the water outflow for the purpose of irrigation in a downstream area through the canal system. Today, it is the symbolic water body in the city of Jaipur and a natural habitat for various local and migratory birds.

Jalmahal

It is the monument which forms the genius loci of the area.  The conservation of Mansagar lake was built in 1732 A.D. Mansagar lake is a pleasure palace and is a fine example of Indo- Saracenic architecture. The building is like a large pavilion sited inside the lake and its roof terrace acts like a viewing platform with chhatris on the four sides and plantation to provide a cold breeze.
The conservation of Mansagar lake lower stories of the building is designed as stairways and passages facilitating access to the terrace located on top of the structure. The corridors and archways provide framed views of the lake.

Why 

The restoration of conservation of Mansagar lake came with the inflow of tourism in Jaipur. The conservation of Mansagar Lake and Jal Mahal Palace, both needed to be restored to increase the tourist attraction.
The lake was suffering from the inflow of wastewater through two major drains namely Brahmaputra and Natalia as these drains pass through the urban area.

Erosion of soil from the hills during the rains was adding turbidity and reduction in the water holding capacity. Artificial land formations were taken place and the lake area was being encroached upon by cultivation in the lake bed.
The conservation of Mansagar lake was suffering from hyper eutrophication and the water surface was covered with excessive phytoplankton and algal growth.

Over the years a high level of accumulation of pollutants in the lake sediments was being released regularly due to anaerobic conditions in the lake bottom. Due to these reasons, the lake water quality was not fit for even wildlife and fisheries.
A channel of 15km was constructed to divert the drain and stormwater. The basin for silt imitation was constructed towards of the east of the lake. The silk deposited into the lake reduced the water storage capacity.

Artificial land formations had taken place. Lake area has encroached upon cultivation was being done in the lake bed. There was no lake edge. The banks were made to view the beauty of the lake and palace.

Development of promenade along Amer road in 1km length and tourist trail from Amer road to Mansagar dam is 2km length drive. The plantation work on the lakeside slopes has been done to strengthen the bank and improves the environment.

The conservation of Mansagar lake north side of the lake is surrounded by hills. It was necessary to provide a check on soil erosion from the hills. In addition to this, it will also work as a separate water body for wildlife.

It is a natural habitat for more than 150 species of local and migratory birds. Nesting islands have been created in the northern and eastern shore of the lake to encourage the growth of weeds, shelter, and food which will result in a good habitat for resident and migratory birds.

The conservation of Mansagar lake erosion of soil during the rains from the hills of the lake catchment area was adding silt into the lake. The Arch point also does these type of work The treatment on steep slopes was necessary for in-situ conservation. So the construction of loose stone check dam and contours was done on steep slopes of hills to check the soil erosion.
