Construction of Check dams, silt traps, toe walls and cascading for controlling silt entry
The aim of the catchment area treatment of the lakes is to mitigate inflow, ofsilt,agricultural residues and other wastes etc. into the lake through inlet channels discharging into the lake. This has been achieved by constructing gabion structures, check dams silt traps and toe walls on all the inlets channels leading to the Upper & Lower lake. Under this sub-project at 3 Nallas (Banganga, Hindi Granth Academy & MVM) into the catchment area of lower lake and 12 Nallas (Halallpura, Laukhedi, Bairagarh Kalan, Bhainsakhedi, Intkhedi, Sirsa Nala, Mugaliya Chhap, Gora nala, Kotra Sultanabad, SAF Nalla, Bhauri & Jamunia Chhir Nala) into the catchment area of Upper lake, a total number of 75 check dams, high level gabion structure, low level gabion structure and 2 silt traps has been executed. The details of the structures constructed have been tabulated as below:-
