Narrabeen Lagoon Recreational Dredging

This consultation has concluded."

Some user groups have asked Warringah Council to dredge sections of Narrabeen Lagoon to allow better access for sports such as fishing, sailing and kayaking.

The Lagoon has been dredged for recreational use in the past. However, recent investigations have indicated that dredging may also have some environmental impact.

There may need to be some trade-offs to get the balance right and getting that balance right means that we need to hear from the broader community, local residents and users of the lagoon.

  • Installation of Navigational Marker Buoys Planned

    10 months ago

    Following consultation with Roads and Maritime Authority, Industry and Investment (Fisheries), Crown Lands, and key user groups, we will be installing strategically placed marker buoys around the edge of the shallow seagrass areas of Narrabeen Lagoon to aid navigation.

    View Marker Buoys Map

    This proposal has the advantages of:

    • Identifying the shallow areas in the central basin of the lagoon to users and directing them to deeper water
    • Identifying legislatively protected seagrass beds and routes around them which in turn may lead to an increase in marine biodiversity in the lagoon
    • Not ‘overcrowding’ the lagoon with markers thus reducing visual clutter and obstacles

    In determining the best locations and design for the marker bouys, we took into consideration popular recreation routes, depth, shallow seagrass areas and international navigation guidelines.

  • Narrabeen Lagoon Recreational Dredging – Council Decision on the Dredging Options

    almost 2 years ago

    A report was presented to Council on 29 April that described the community feedback on the recreational dredging options.

    View the Council report

    There was a range of support from within the community for the three dredging options and the option not to dredge. 

    Due to concerns about environmental impact, low overall benefit and high cost, Council resolved to first implement non-dredging options to aid navigation before determining whether to proceed with dredging.

    Non-dredging options include installing signage and marker buoys to aid navigation through existing channels, better management of existing users and a review of the lagoon’s opening and closing procedure. 

    After implementing the non-dredging options, and after approaching Pittwater Council and State Government for consultation and funding support, Council will then determine which of the available dredging options should be implemented.

  • Narrabeen Lagoon Dredging Options - Open for comment

    over 2 years ago

    Council has prepared a discussion paper detailing three feasible dredging options for Narrabeen Lagoon. 

    View the Discussion Paper

    This followed an extensive study of the environmental feasibility and cost/benefit of a range of dredging options in Narrabeen Lagoon. 

    Have your say

    • Complete online feedback form 
    • Write to warringah Council 725 Pittwater Road, Dee Why 2099, Marked: Narrabeen Lagoon Dredging 

    Comments close 10 February 2014

    An indicative estimate of dredging costs, seagrass mapping, a bathymetry survey, a revised cost estimate and a study of aquatic recreation were conducted. From these, three options for dredging were proposed that are both financially feasible and offer benefit in the busiest areas to the greatest number of users.

  • Narrabeen Lagoon Dredging Options

    over 2 years ago

    The feasibility study was based on a list of 31 preferred locations for dredging that were put forward by recreation clubs, stakeholders and community in 2012.

    The 31 sites were assessed against environment, legislation and other dredging requirements. Of the 31 sites, 12 were found to be potentially environmentally feasible.

    A report on the shortlist was presented to Council in April 2013

    View Council report

    From this, Three options were proposed for dredging. These options were identified as being both financially feasible and offered benefit in the busiest areas to the greatest number of users.

    Dredging offers benefits to water craft by providing access channels between the south of the lagoon (at Jamieson Reserve) and the deeper waters in the north and east. The benefits are expected to be most experienced by kayakers, paddlers, small boats and sailors in the central area of the lagoon, Dredging will not result in notable change in the flushing and water quality. It also presents a risk to important ecological species of the lagoon and comes with a relatively high financial cost. It is therefore important that Council receives input from the community about the potential options.

    Your feedback, along with the recommended option will be reported to Council in March 2014.

    Council has developed a short list of 12 potential options for recreational dredging in Narrabeen Lagoon. The short list was developed from 31 options that had been put forward by the community during the Stage 1 community consultation. The feasability of each option was assessed against environmental and legislative requirements and graded as “feasible”, “unfeasible” and “requires more data”. Further data was then collected to finalise the short list, including:

    • A seagrass survey for the whole lagoon (February 2013): A seagrass map was developed to quantify the environmental impact of each of the dredging options
    • An aquatic recreation study (April-June 2013): Surveys of on water recreation and surrounding infrastructure conducted under various environmental conditions and days of the week. The results are being used to estimate the recreational benefit of each short listed dredging option
    • Cost estimates for dredging a variety of combinations of the short listed options (May 2013). The cost estimates are used to quantify the financial impact of dredging

    The following documents are now available:

    1. Interim Report on Narrabeen Lagoon Recreational Dredging 
    2. Map and List of Feasible Dredging Sites 
    3. Narrabeen Lagoon Seagrass Mapping 2013 
    4. History of Dredging in Narrabeen Lagoon 

    A cost, benefit, impact and risk assessment is now underway for 12 short listed options. This assessment will be used to develop final recommendations for Council to consider by December 2013.

  • Stage 2 Feasibility Assessment

    about 3 years ago

    The Stage 2 Feasibility Assessment commenced in October 2012 and it aims to find out if any areas can be dredged with minimal impact to the lagoon’s ecology. The Stage 2 Feasibility Assessment will also consider the financial and recreational feasibility including the costs to dredge, the potential benefits to recreation and any associated impacts.

The Stage 2 Feasibility Assessment will also consider the financial and recreational feasibility including the costs to dredge, the potential benefits to recreation and any associated impacts.

    The Feasibility Assessment is broken down into a series of tasks:

    • Identify a short-list of potential dredging locations
    • Undertake a risk analysis
    • Compile existing environmental impact information
    • Assess any impact on flood management
    • Assess any impact on the surrounding shore and future infrastructure needs
    • Identify project costs and potential benefits

    Community information sessions will be held at various stages to provide updates and receive feedback. At the end of Stage 2, a report will be presented to Council to then decide whether to proceed to Stage 3 – a detailed design and works stage.

    For more information contact Council on 9942 2111.

  • Stage 1 results

    by site admin 1, over 3 years ago

    The Stage 1 Community Consultation aimed to understand the broader community’s support for dredging in Narrabeen Lagoon to improve recreation, and it was found that half of the community (51%) are in support of dredging while 22% of people are opposed to the idea. A significant number in the community (81%) believe that it is important that there are no environmental impacts from dredging.

    These results were presented to Council on 24 July 2012, and it was decided that there was enough broad community support to take the project to the next stage and assess the feasibility of dredging in the lagoon.
