  1. CONSERVATION, RESTORATION & MANAGEMENT OF LAKES Jahnavi R, Jyotsna Sripada & Divya P Vidyaniketan Pre-University College Ullal Upanagar, Bangalore 560 056 December 28, 2006

  2. OBJECTIVE • STUDY OF CONSERVATION, RESTORATION AND MANAGEMENT OF LAKES. • EMPHASIS ON CONTRIBUTION OF LAKES TO OUR ECO-SYSTEM.

  3. INTRODUCTION USES OF LAKES : • ESSENTIAL FOR HUMAN HABITAT • HOME TO BIRDS, FLORA & FAUNA • USEFUL IN RECHARGING GROUND WATER • VITAL PART OF THE FRESH WATER ECO-SYSTEM • FLOOD CONTROL AND STORM PROTECTION

  4. INTRODUCTIONcontd. • CAUSES FOR LAKE DEPLETION: • INADEQUATE RAINFALL • INDUSTRIAL WASTES • DIGGING OF BOREWELLS • UNPLANNED URBANIZATION

  5. PROJECT STUDIES • Sample analysis of Ullal lake. • Conclusion of a survey conducted in the area. • Interview with an environmentalist • Detailed study of Ulsoor lake .

  6. SAMPLE ANALYSIS OF ULLAL LAKE

  7. INTERACTION WITH PUBLIC

  8. INTERACTION WITH PUBLIC contd • ACTIVITIES SPOILING THE LAKE: • DUMPING WASTE MATTER • USAGE AS PUBLIC TOILET • IMMERSION OF IDOLS

  9. LAKE PROBLEMS • EUTROPHICATION – The ageing process • SEDIMENTATION – Soils wash into the lake • EXCESS ALGAE – Microscopic aquatic plants • CONTAMINATION – Pollution from toxic substances • ATMOSPHERIC DEPOSITION OF POLLUTANTS

  10. EXCESSIVE WEED GROWTH

  11. DUMPEDGARBAGE

  12. CONSTRUCTION MATERIAL

  13. DYING AND DECOMPOSING BLUE GREEN ALGAE BLOOM

  14. BREEDING MOSQUITO LARVAE

  15. STRATEGIES FOR RESTORATION (ULLAL LAKE) • ADHERENCE TO WATER QUALITY STANDERDS(WQS) • WEED REMOVAL • AFFORESTATION ALONG TANK BUND • DESILTATION • PREVENT POINT SOURCE OF POLLUTION • CORRECT NON-POINT SOURCE POLLUTION PROBLEMS

  16. DETAILED STUDY OF ULSOOR LAKE Size: 50 acres Current problems: • HYACINTH INFESTED WATER • CONTAMINATED WITH SLIME • UNCHECKED EFFLUNTES • SEWAGE DISCHARGE • UNPLANNED URBANISATION

  17. STUDY OF ULSOOR LAKE CONTD • SUGGESTIONS FROM “SAVE ULSOOR LAKE FOUNDATION” • DESILTING OF LAKE • MEASURES TO PREVENT SEWAGE AND POLLUTANTS

  18. EFFECT OF INADEQUATE DISSOLVED OXYGEN

  19. LOST LAKES

  20. KEMPEGOWDA BUS STATION – ONCE DHARMAMBUDI LAKE

  21. GOLF COURSE- ONCE CHALLAGHATTA LAKE

  22. STADIUM – ONCE SHOOLAY LAKE

  23. RESIDENTIAL LAYOUT – ONCE KORAMANGALA LAKE

  24. lake Conservation • DEVELOP AQUATIC LIFE • PREVENT ENCROACHMENT • SET UP AN INTERAGENCY REGULATORY BODY • INVOLVE INSTITUTIONS AND COLLEGES INWATER QUALITY MONITORING • CREATE PUBLIC AWARENESS.

  25. IN-LAKE RESTORATION TECHNIQUES

  26. AQUATIC PLANT CONTROL TECHNIQUES

  27. WETLAND MANAGEMENT • INTENSIVE MONITORING • INTERACTION AND COOPERATION AMONG VARIOUS AGENCIES INVOLVED • MAINTAIN IMPORTANT NATURAL PROCESSES THAT OPERATE ON LAKES THAT MAY BE ALTERED BY HUMAN ACTIVITIES • CONDUCT REGULAR WATER QUALITY MONITORING • CREATING BUFFER ZONES FOR LAKE PROTECTION • DEVELOPMENT OF WATER QUALITY DATABASE • ANALYSE AND DISCUSS CASE STUDIES

  28. CONCLUSION • ENVIRONMENTAL PRESSURE OF UNPLANNED URBANIZATION AND GROWING POPULATION HAVE TAKEN ITS TOLL ON WETLANDS. • LAKES ARE POLLUTED MAINLY DUE TO SEWAGE FROM DOMESTIC & INDUSTRIAL SECTORS • IT REQUIRES IMMEDIATE ATTENTION FROM THE AUTHORITIES TO RESTORE THEM

  29. HAD ALL THE LAKES BEEN PROTECTED, BANGALORE WOULD HAVE BEEN NEXT TO WALES OF U.K.
