Intention
To create a pond area with an island to function as a
silt deposition site for incoming water borne sediments, thus preventing the silting of
the Wetland and Lake areas.
To construct an access road for excavation machines so
as to allow future removal of accumulated silt.
Method
1) Excavate silt to provide a maximum depth of
1.5 metres.
2) Pond sides shelved.
3) Construction of spillway using Gabion basket
structures incorporating waterproof membrane, geotextile
fabric, stone retaining wall and concrete
base.
4) Lay two 500 mm x 6 metre "Armco"
pipes into the Wetland to convey overspill; these in turn to be overlain by the surfaced
access track.
5) Plant pond shores and hinterland with willow
and introduce indigenous flora from recently established stock in the Wetland area. |
