Tabourie Lake Entrance Management Review

Consultation has concluded

Shoalhaven City Council is currently reviewing the Entrance Management Policy for Tabourie Lake.

In conjunction with the NSW Government, Council is responsible for managing the entrance of Tabourie Lake for the purpose of flood mitigation. The Tabourie Lake Entrance Management Policy and Review of Environmental Factors (Peter Spurway & Assoc., 2005) (pdf 500KB) documents the procedure for opening the Lake.

This document has been in place for over 10 years now. Council has also recently updated the Tabourie Lake Floodplain Risk Management Study and Plan with better information. Therefore, Council has engaged consultants Cardno (NSW/ACT) to undertake a review of the document to ensure best practice is achieved in managing flood risk.


Background

Tabourie Lake is an ICOLL or Intermittently Closed and Open Lake or Lagoon. At times, the Lake is blocked off from the open ocean by a sand berm. The sand berm is formed by wave action across the estuary entrance. When the entrance is closed, there is no tidal flushing of the estuary and the water levels are largely controlled by catchment rainfall, with some potential for waves to overtop the berm. When Lake water levels rise in response to rainfall, the entrance berm may be breached and scoured away by floodwaters.

Due to the presence of low-lying development around the Lake, Council prepared an Entrance Management Plan (Spurway and Assoc., 2005) to manage the impacts of flooding on infrastructure and properties. It provides for mechanical opening of the Lake entrance by Council to artificially lower water levels.


Community Workshop Presentation

On the evening of Monday 9 August 2017, Council held a community workshop at Lake Tabourie Rural Fire Shed. The workshop was held to discuss the progress of the project and to receive feedback from the community regarding the proposed options. The workshop was well received by those who attended.

Consultants Cardno provided a presentation which was followed by question time and a discussion with Council staff and the Consultants. A copy of the slides from the presentation has been provided below.
