Sideling Creek Dam, also known as Lake Kurwongbah, is built on a tributary of the Pine River and is part of South East Queensland’s drinking water supply.

It is an un-gated dam, meaning that when it reaches 100 per cent capacity, water flows over the spillway and safely out of the dam. If you would like to be notified when Sideling Creek Dam begins to spill, please sign up to our free dam release notification service.

Visiting the lake

The surrounding environment and recreation facilities available make Lake Kurwongbah popular for fishing and picnicking. Fishing is permitted from paddle craft and from the shoreline at designated recreation areas. No permit is required.

Changes to the shared recreation arrangement at Lake Kurwongbah were introduced in June 2015 and still currently apply - click here to read the update or download the brochure.

More information including maps are available in the Lake Kurwongbah Recreation Guide*.

Note: Recreation at, and access to, our sites may have changed since the recreation guides were published in 2014. We are in the process of updating these guides to simple one-page recreation maps. Until then, please refer to for the most recent updates about recreation activities and site access.

Future recreation changes at Lake Kurwongbah

Public rowing, paddling and club skiing will soon be permitted on Lake Kurwongbah, seven days a week.

In June 2015, changes were made to the shared recreation arrangement at Lake Kurwongbah, while a landmark water quality assessment was undertaken at the neighbouring Lake Samsonvale.

The Australian-first study has increased Seqwater’s knowledge about the impact recreation has on water quality, which has allowed us to revise the current shared recreation arrangement on Lake Kurwongbah and provide more access opportunities.

We will be working with local recreation clubs and immediate neighbours over the coming months to carefully plan these changes at Lake Kurwongbah.

More information will be available as planning progresses in 2017.

Dam Improvement Program

Dams are long-life assets and require continued assessment, monitoring and maintenance.

In 2012-13, we commissioned an independent review of our 26 regulated dams, which found improvements are needed at a number of these dams to meet Queensland dam safety guidelines into the future.

In 2018-19, Seqwater will be upgrading Sideling Creek Dam, as part of the Dam Improvement Program. Sideling Creek Dam is one of five dams across the region identified for upgrade in the next 5-6 years.
