Lake Cressbrook is a reservoir formed on Cressbrook Creek, situated approximately 60 kilometres northeast of Toowoomba and 21 kilometres east of Crows Nest National Park in Queensland's Darling Downs region. It is listed as a paddling destination on the Southeast Queensland coast circuit and offers calm, flatwater conditions well suited to recreational paddle craft.

Access to the water is via a boat ramp located at Loveday Cove within the Day Use Area. Paddling is restricted to the hours the Day Use Area is open: 6am to 8pm during summer months (September to April) and 7am to 6pm during winter months (May to August). Water-based activities are not permitted outside these hours, and this restriction applies to campers as well as day visitors.

Only paddle craft and electric outboards are permitted on the lake; conventional motorized vessels are not allowed. Swimming is prohibited. As the lake sits within a designated flora and fauna reserve, no pets are allowed on site. Generators are also not permitted.

The lake supports a notable variety of birdlife, including large numbers of Eurasian coots, and grey kangaroos are commonly seen in the surrounding area. Feral deer are occasionally spotted in the inland bushland. A walking track (Grade 3, approximately 7,455 metres, taking around 150–160 minutes to complete) begins near the boat ramp and follows the lake's edge before looping back through bushland, providing good vantage points for observing water birds.

Camping is available on site, and a picnic and day use area with a children's playground and sand volleyball court adjoins the boat ramp. Firewood is not available for sale or collection on site and must be brought in. Anglers paddling the lake require a Freshwater Fishing Permit (Stocked Impoundment Permit), available from local post offices or by contacting the Queensland Government Contact Centre on 13 13 04.

To reach Lake Cressbrook from Toowoomba, travel north to Hampton on the New England Highway, then take the Hampton–Esk Road through Ravensbourne, turning onto Mount Jockey Road and following signs to Cressbrook Dam.
