Wallis Lake Estuary Management Plan
Management Objective Effectively control and mitigate erosion of foreshore reserves; Pipers Creek foreshore reserve, Rest Point Road reserve, John
Wright Memorial Park, Darawakh Reserve, Oxley Park
M.3
Management Area A, C, D
Action
No
M.3.1
M.3.2
M.3.3
M.3.4
Action
Conduct a bank assessment of foreshore reserves and identify and prioritise
bank protection structures in need of repair, and areas in need of further
protection from erosion
Conduct repairs on retaining walls identified in M.3.1, and consider constructing
new bank protection structures where necessary as identified in M.3.1
Formalise access areas to the estuary at Rest Point Road reserve by
constructing at least two sets of steps leading to the water and transplant Juncas
sp (Tussock Rush) to stabilise the surrounding bank
Formalise an access area to the estuary at Darawakh reserve ( ie. platform) and
encourage revegetation and bank protection of the surrounding foreshore area
by mangroves and casuarinas

Comments
Erosion is still active at some foreshore reserves where retaining walls have been constructed. In addition to being a source of sediment to the lake, this has lead to undercutting
of the retaining walls and has caused footpaths to slump creating trip hazards.
For Darawakh and Rest Point Road reserves, formalising access points and revegetation of the foreshore is the most appropriate method to stabilise the bank and prevent further
erosion. It is recommended that signage be constructed at these areas outlining the objectives of the revegetation efforts and requesting that people avoid trampling the newly
planted vegetation. The recommended works for Darawakh reserve will prevent boats from being launched at the area, which is contributing further to erosion, as there is no
formal boat launching facility at the reserve. If a platform is considered for Darawakh Reserve, NSW DPI and the Wallis Lake Fish Coop should be carefully consulted to ensure
that existing fishing grounds are not adversely affected.
