Use of dredging methodology:
- Research has taken the help of geotechnical, hydraulic and satellite images studies and developed a dredging methodology.
- The project involved the excavation (loosening or dislodging) of unwanted substances from the foothills without damaging the lake’s ecosystem, removing the loosened material to the dredge vessel & transportation of the material to the placement area.
Benefits of the project:
-As per the IIT team involved in the project, the research benefited more than 200,000 fishermen living in 132 villages as now seven times more fish can be caught.
-The project reduced unwanted freshwater weeds and the biodiversity as well as the ecosystem of the lake get improved. In addition, the production of fish has increased seven-fold and the number of endangered Irrawaddy dolphins has also increased.
-The lake has been renovated at a cost of Rs 10 crore by opening the mouth and other related works in a short period of 6 months & is now off the threatened list (Montreux record).
