Lakes in Bangalore
Lakes in Bangalore, Karnataka are numerous, and there are no rivers close by. Most lakes in the Bangalore region were constructed in the sixteenth century by damming the natural valley systems by constructing bunds.
The effect of urbanization has taken some heavy toll on the lakes of Bangalore. The lakes in the city have been largely encroached for urban infrastructure and as result, in the heart of the city only 17 good lakes exist as against 51 healthy lakes in 1985. Urban development has caused 19 lakes getting converted to bus stands, Golf courses, playgrounds and residential colonies, and few tanks were breached under the malaria eradication programme.
In recent years, the Management of Lakes traditionally done by the government agencies witnessed experimentation by the Lake Development Authority with a limited public-private sector participation in respect of three lakes, which has proved controversial and resulted in almost a reversal of the policy.
History
The earliest history of creation of lakes in and around the city is traced to the founders of Bangalore or Bengaluru -the Kempe Gowdas- in the Sixteenth century and later by the Wodeyars of Mysore Kingdom and the British.Most of the lakes and tanks were man made for purposes of drinking water, irrigation and fishing needs and they have also favorably influenced microclimate of the city. The lake waters have also served as "Dhobhi Ghats" or places where washer-men, have traditionally used them as a means of livelihood for washing clothes and drying them. The lakes have also served to replenish ground water resources in the vicinity, which are tapped through wells for drinking water.
In the 1960s the number of tanks and lakes was 920 and less than 580 in 1993. Until 1895 unfiltered water was supplied from tanks like Dharmambudhi, Millers tank, Sankey and Ulsoor tanks. From 1896 water was supplied from Hessarghtta and from 1933 it was also obtained from Thippagondanahalli. In the 1970s the scheme to pump water from the Cauvery river 100 kilometres away was begun. The water needed to be raised up by 500 metres.
The water demand in 2001 was 750 million litres per day and the actual supply is only 570 million litres per day and the per capita usage is about 105 litres per day. The national standard is 150 litres per day while the international standard is 200 litres per capita per day.
Encroachment
Most of the lakes have vanished due to encroachment and construction activity for urban infrastructure expansion. The city once had 280-285 lakes of which 7 cannot be traced, 7 are reduced to small pools of water, 18 have been unauthorisedly encroached by slums and private parties, 14 have dried up and are leased out by the Government. 28 lakes have been used by the Bangalore Development Authority to distribute sites and build extensions for residential areas. The remaining lakes are in fairly advanced state of deterioration.- Challaghatta lake changed to Karnataka Golf Association

Topography and hydrology
Water resources are important for urban areas as they provide for a wide range of uses. Bangalore, with annual rainfall of with three different rainy seasons covering nine months of the year. June to October is the rainy season accounting for 64% of the total annual rainfall in the S-W monsoon period and during the N-E monsoons. It has a salubrious climate with an annual mean temperature of with extremes ranging from to . The streams between ridges and valleys have been dammed at suitable locations creating a cascade of reservoirs in each of the three valley systems. Each lake stores rain water from its catchments with excess flows spilling downstream into the next lake in the cascade.
The storm water runs off through drains only. These drains often carry sewage in it, which results in the lakes getting polluted. Many lakes have reportedly springs at the bottom of the lakes, some of which are stated to be choked due to silt, which also feed the lakes.
The dependence on lakes, tanks, ponds, wells and other sources, in the past for supply of raw water to the city was de-linked with treated supplies arranged from river based schemes such as the "Chamarajendra Water Works" built in 1894 and the "Chamarajasagar Reservoir" at T G Halli across the Arkavathy River in 1933 and subsequent sourcing from the Cauvery River schemes.

;Fauna: The fauna recorded are: freshwater turtles, frogs, naiads, crabs, molluscs, Notopteris notopteris and many more.
Status
The lakes of the city have been largely encroached for urban infrastructure, and as result, in the heart of the city only 17 good lakes exist as against 51 healthy lakes in 1985. According to a scientific study carried out by the Centre for Ecological Sciences, Indian Institute of Science, Bangalore, the water bodies of the city have reduced from 3.40 per cent in 1973 to just about 1.47 per cent in 2005 with built up area during the corresponding period increasing to 45.19 per cent from 27.30 per cent. The adverse results of such large change are reported to be:- Frequent flooding and micro-climatic changes in the city
- Undesirable impact on the diversity of flora and fauna
- Decrease in the number of migratory birds
- Fishing community and washer-men will be robbed of their livelihood
Management
Historically lakes in the Bangalore region were managed by a plethora of government agencies such as the Forest Department, Minor Irrigation Department, Horticulture Department, Public Works Department, Bruhat Bengaluru Mahanagara Palike, Bangalore Development Authority, Tourism Department, City Municipal Councils and Panchayats; each organisation claiming its own jurisdiction of ownership and maintenance rights resulting in a deficient, inconsistent and uncoordinated approach.Expert Committees set up by the Karnataka Government, since 1986, highlighted the failure of the various bodies maintaining lakes in protecting them and also suggested that:.
- Existing tanks not be breached but retained as water bodies
- Efforts should be made to ensure that the tanks are not polluted by discharge of effluent and industrial wastes
- Prevent silting up of the tanks by offshore development through tree planting and also removal of encroachments
- Breached Tanks not be used for formation of sites but should be used to create tree parks
- De-weed all tanks and develop aquatic life
- The tank areas where there are no atchkat should be transferred to the Forest Department for developing tree parks/foreshore tree planting and formation of regional parks
- Encroachments on tank areas by the Bangalore Development Authority / Bangalore City Corporation / Minor Irrigation Department to be removed
- Monitoring of progress of all the above activities by the Forest Department, Bangalore Development Authority, Bangalore City Corporation, Minor Irrigation Department, Bangalore Water Supply an Sewerage Board and Town Planning Department
- Bangalore Water Supply and Sewerage Board to be entrusted with the responsibility for the maintenance of water bodies in a clean and safe condition
- Examine possibility of construction of more tanks along the natural valleys with surplus runoff and implemented.
Lake Development Authority
The Government of Karnataka, following the directive of The Honourable High Court of Karnataka and considering the unchecked deterioration of lakes in and around Bangalore and keeping in line with their critical role in maintaining healthy environs and recharging of ground water, set up the Lake Development Authority in July 2002 as a registered society under the Karnataka Societies Registration Act, 1959, as a non-profit organisation and a para-statal body with a mandate ofA Governing Council and other groups have been set up for the smooth functioning of the LDA. LDA's jurisdiction has been extended, in July 2003, to cover other city corporations and town municipalities in the State. The Authority is high powered body headed by a Chairman who is the Chief Secretary, Government of Karnataka, Additional Chief Secretary, Government of Karnataka as Vice-Chairman, with a Chief Executive Officer, Lake Development Authority as Member Secretary with other members drawn from Planning, Science and Technology Department, Forest, Ecology and Environment Department, Finance Department, Information and Tourism Department, Urban Development Department, Minor Irrigation Department. Animal Husbandry and Fisheries Department all at the level of Principal Secretaries to the State Govt, Director, NRCD, as representative from MOEF, Government of India, The Secretary, Department of Forest, Ecology and Environment, the Secretary to Government Agriculture and Horticulture Department, Chairmen of Karnataka State Pollution Control Board and Bangalore Water Supply & Sewerage Board and Commissioners of Bangalore Mahanagara Palike and Bangalore Development Authority.
working solely for the regeneration and conservation of lakes in and around Bangalore city within BMRDA jurisdiction in the first instance, would be extended to other parts of Karnataka subsequently.
.
The defined charter of functions of the LDA is:.

- The National Lake Conservation Programme under the Ministry of Environment and Forests, Government of India have funded restoration works of Vengaihnakere, Jaraganahalli - Sarakki and Nagavara lakes implemented by the Forest Department of the state
- The Bangalore Mahanagara Palike or the Bangalore City Municipal Corporation has carried out restoration works of the Yediyur Lake, the Kempambudi Lake, the Ulsoor Lake, the Sankey tank, the Tavarekere and the Byrasandra Lake.
Privatisation
In 2004, the LDA, which is a parastatal organisation, began a process of "public-private participation" where private companies bid for the lakes to "develop and maintain" them for the next 15 years with the specified Terms of Reference. The tender specified the following Terms of Reference.- Desilting, dredging, sewage diversions, constructed wetland, bio-remedial measures
- Construction of water treatment plants, chain link fencing
- Landscaping and gardening
- Foreshore and island development
- Creation of tree parks, rock gardens
- Walkways, jogging path, cycling track
- Fountains, children play area
- Electrification for illumination
- Boat jetty
- Eco-friendly restaurants
- Urban fishing, bird watching, butterfly park, aviaries and boating
In May 2006, LDA leased out the Hebbal Lake, one of the largest lakes in Bangalore, to East India Hotels for a period of 15 years for an annual lease amount of Rs. 72,10,000 and an annual escalation of 1.5% in the amount and an Investment of Rs.16,75,00,000 with a security deposit of 1.5% under the Public-Private Partnership policy.
The Nagavara Lake was leased to Lumbini Gardens Pvt Ltd in April 2005 for a period of 15 years for an annual lease amount of Rs.4023,000 with an annual escalation of 1.5% of this amount every year for the 15-year lease period and with Investment of Rs.7,01,00,000 with a security deposit of 2% of this amount.
As per the lease agreement, the above referred agencies were to carry out the development and maintenance of the lakes by:
- Setting up water treatment plant
- Deweeding the lake
- Controlling of storm water entry by building check dams
- Do land scaping, build a rose garden and also a rock garden
- Build jogging tracks and erect fountains
- Put up high Buddha statue.
- Develop an artificial beach as an amusement activity
- Develop water sport activities such as aqua karting, water scooter rides and paragliding
- Set up food courts, restaurants, including a floating restaurant
Impact
- There is dichotomy in the functions allocated by the vesting of powers with LDA to maintain only the water body and some part of the shore line while the shore and lands adjoining the lakes, which also play an important role in the overall maintenance and health of lakes, are with district bodies. This state of affairs creates a complex situation of not addressing the lake as a continuum with land.
- The lakes are being developed as stand alone water bodies without a linkage to other lakes
- Land use regulations are violated as the private developers of the two lakes have not sought permission for change in land use from the Bangalore Development Authority for converting the Nagavara and Hebbal Lakes for commercial use; a case of non compliance of the law.
- Fauna dependent on the lake, like birds, fish and others are disturbed by the excess and disturbing human activity
- Conversion of the lakes and their surrounding areas into exclusive resorts, with entry fee access to the lake areas. The private developers are in the real estate/hospitality business with profit motive
- Violation of land use regulations by the private organisations while implementing the scheme
- Proposed construction of a 223-room Hotel at the side of Hebbal Lake is indication that private developer has taken the lease purely for commercial and business purposes. Such a development would exclude access to the lake for the general public.
- Lakes are common property resources, in which a group of people have co-user rights. The impact of the privatisation scheme would, therefore, need to be addressed legally
- The socio-economic impacts or apprehensions of the people such as fishermen dependent on the lake for livelihood is that there could be restrictions on their fishing rights and washer-men also have similar apprehensions
Protests
LDA’s contention
The Lake Development Authority contends that the organisation is not adequately staffed and that they do not have the finances for maintaining lakes on an ongoing basis. Hence, the alternative is leasing out lakes to private parties.Public interest litigation
A Public Interest Litigation has been filed in 2008 by an Environmental Support Group and a public spirited individual of Bangalore in the High Court of Bangalore citing 16 respondents with the Lake Development Authority as the second main respondent and the favoured respondents namely M/s Biota Natural Systems Pvt. Ltd, M/s Lumbini Gardens Ltd., and M/s E. I. H. Limited, in respect of the ongoing privatisation of lakes/tanks in Bangalore. The PIL contends that:- Actions taken by the respondents are against settled legal norms in respect of Management and conservation of such ecologically sensitive water bodies and which support a variety of customary and traditional rights
- Water bodies are located in prime areas of the city and beneficiaries of privatisation of these are largely hoteliers and builders, as it is not an environmentally progressive purpose but more a manipulation of the policy with profit motive
- The constitution of the Lake Development Authority expressly prohibits privatising these public water bodies against the wider public interest
Policy turnaround
With the privatisation approach for development and management of lakes not proving to be popular, and considering the serious protests by the public and the pending Public Interest Litigation in the High Court of Karnataka seeking redress, the Government of Karnataka has now decided to make amends with a paradigm shift in its approach by declaring that the State Government would undertake, through its agencies such as the Bangalore Development Authority, BBMP and Bangalore Metropolitan Region Development Authority, the rejuvenation works of 27 lakes in the Phase I by allocating finances to the extent of Rs 1.5-2 crores per lake which would involve:- Desilting of the lake bed
- Diversion of sewage and other processes
- Free access to the public
- Discontinue the policy of privatisation of lakes and
- Revisit the allotments already made to private parties in view of reported misuse of the lake property by encroachment for private gains
