We are so proud of our town…our beaches, golf courses, marinas, parks, housing opportunities for all, businesses, industrial parks, healthcare and educational institutions including our own Islip MacArthur Airport that provides many job opportunities.

We are so excited to finally be moving forward with this long overdue Park improvement. We thank you for your patience and understanding while the Town works to renovate, rehabilitate, modernize and ultimately improve Byron Lake Park. This will be an attraction and asset for all Town of Islip residents to enjoy for many years to come.

At a glance: Work is currently underway to renovate the Byron Lake Park pool, concession area, septic system, as well as improve accessibility and surrounding beautification. Byron Lake itself is also being rehabilitated.

Residents are encouraged to use this page as a resource through the duration of the project, and to check back periodically for additional news and updates.

    • Byron Lake Park may be closed to the public for safety reasons at intervals beginning October 3, 2022. Every attempt is being made to have some areas, when practical, available.

  7. What other work is planned for the pool project?

    • Upgrades to the septic system are being done per Health Department requirements.

    • Plans call for tree trimming and the removal of any dead or dying trees. There is no plan at present to remove trees that provide a buffer between the park and homes.

  8. When will construction take place?

    • Construction for the pool will be done during normal business hours.

  9. What is the overall scope of the lake project?

    • The lake project involves rebuilding the existing bulkhead, some reconstruction on the south end of the lake, and reconstructing the culverts for the walkways along the stream.

  10. Will water quality be a factor?

    • The lake water quality will improve once bulkheading, culverts, and other areas have been rehabilitated.

  11. Will the site be secured?

    • The site will be safely secured.
