Sukhna Lake(Hindi: सुख़ना) in Chandigarh, India is a reservoir at the foothills of the Himalayas, the Shivalik hills. This 3 km² rainfed lake was created in 1958 by damming the Sukhna Choe, a seasonal stream coming down from the Shivalik Hills. Originally the seasonal flow entered the lake directly causing heavy siltation. To check the inflow of silt, 25.42 km² of land was acquired in the catchment area and put under vegetation. In 1974, the Choe was diverted and made to bypass the lake completely, the lake being fed by three siltation pots, minimising the entry of silt into the lake itself.

The creation of the lake was one of the greatest gifts from Le Corbusier and the Chief Engineer P L Verma to the city of Chandigarh. To preserve its tranquility Corbusier insisted that it be forbidden to motor boats and the top of the dam (promenade) prohibited to vehicular traffic. The lake is fringed by a golf course to the south, and Nek Chand's famous Rock Garden of Chandigarh to its west.
Sukhna is an inseparable part of the city of Chandigarh. Le Corbusier had foreseen that the residents of the city would be drawn it for the 'care of the body and spirit'. The city planners were deeply attached to the lake. So much so that Pierre Jeanneret's ashes were immersed in the lake in 1970 as per his wishes by his niece.
The roof of the 'bandh' or dam has become a favorite promenade. Serious walkers pursue an exercise regime, families enjoy an evening stroll and nature lovers mingle with children on roller skates. Photographers and painters love to capture its scenic beauty of the setting sun, or the heavily clouded monsoon sky, or the early morning mist in winter set amidst the tranquility of the lake. Even anglers do not leave unrewarded.
Sukhna has a membership-based Lake Club with lawns, a gym, indoor games, swimming pool and tennis courts with both synthetic and grass courts. Boating, rowing, sculling, sailing, kayaking and water skiing can be enjoyed throughout the year.
The lake, which was the venue for the Asian Rowing Championships, has the longest channel for rowing and yachting events in Asia. It also has facilities for other water sports like water surfing, skiing and sculling.
Sukhna is a sanctuary for many exotic migratory birds like the Siberian duck, Storks and Cranes, during the winter months. The lake has been declared as a protected national wetland by the Government of India.
During summers, there are streams of men, women and children from all walks of life offering voluntary service to desilt the lake bed for about three months. This annual ritual has been a regular feature since long ago.
Sukhna Lake is the venue for many festive celebrations too. The most popular is the Mango Festival held during the monsoons when scores of varieties of mangoes are on display. From time-to-time other food festivals, featuring specialities from different Indian States, are also held here, along with cultural performances.
Development and Maintenance
The Mera Chandigarh administration has made a decision not to allow fish more than 30 cm in size in the Sukhna Lake 
Chandigarh Administration has finalized new plan for Sukhna Lake and New Lake in Sector 42 with Rs 2.73 crore which has also been received from Union Government.B.A.
The lake is facing serious issues like weed overgrowth, catchment adequacy and silting that are significantly shrinking its size and depth. Additionally, it has also become the subject of litigation between the Chandigarh and Punjab Silting has taken its toll and now the volume of the lake has been reduced to 56% of its original. The lake is now shrinking rapidly due to siltation and lack of inflow. It was initially hoped that the work of desilting could be undertaken in summers at a war footing and dry dredging could be undertaken at a fraction of cost to save Sukhna in the coming years. But unfortunately, the ground realities seem to be different.Due to heavy rain in August and September Sukhna was filt up again and even flood gates were being opened.
Avian Flu Scare
In December 2014, there was an Avian Influenza, or commonly known as Bird Flu, scare which led to a temporary ban on the entry to the premises. The scare started after some migrant geese were found dead in the lake.
However, the administration took great precautions and the geese were culled to check an infection. A score of workers who culled the geese went for a check to be sure that they were safe. The reason behind the death of the geese and the fact that whether there is bird flu scare remains unknown.http://www.thehindu.com/news/national/bird-flu-scare-spreads/article6716900.ece
