Recommendations
Following recommendations has to be taken in Ulsoor lake:
- Regular monitoring of the lake will help in understanding the physico-chemical characteristics and will help in evolving appropriate sustainable management measures.
- Aeration will help in maintaining dissolved oxygen levels, which reduces toxic effects and prevent excessive buildup of vegetation and organic matter.
- Allow only treated sewage which helps in reducing enrichment of nutrients that induces profuse algal growth.
- Restrict dumping of solid waste in the lake bed and lake catchment.
- Leave only treated sewage through construction wetlands and algal ponds (to remove nutrients) as in Jakkur model.
- Implementation of ‘polluter pays’ principle as per water act 1974.
- Dredging (mostly wet dredging) to remove sediments (rich in nutrients) in the lake.
- Public awareness and public participation is necessary.
