A turbidity curtain will be used in the nearshore area during “key-in” of the jetty at the river bank where excavation works will occur. As it is anticipated that greater turbidity will occur during this phase of the work, the turbidity curtain will contain this sediment and allow it to settle out. As noted above, to further mitigate sediment, the rock placement will be slow and controlled (and not require any in-river excavation) and turbidity levels will be continually monitored. Should turbidity levels exceed acceptable levels, defined in the Fisheries Plan, works shall cease to allow conditions downstream return to normal, at which time the works can re-commence.
