Lake Cania is the impoundment formed by Cania Dam on Three Moon Creek, located in Queensland, Australia near Cania Gorge National Park. The dam is an earth and rockfill embankment structure, and the lake itself is characterised by sheer granite cliffs and hills that enclose its various arms, giving it a relatively narrow configuration that provides natural protection from wind and weather. The water is generally very clear and quite deep, making it well suited to smaller boats and kayaks.

Access to the water is via a single-lane concrete boat ramp on Shamrock Road, Cania, Queensland 4630. When water levels drop below the end of the ramp — which reportedly occurs frequently — paddlers and boaters commonly launch from a bank near the dam wall, accessible via a dirt track. There are no boating restrictions on the lake. Facilities at the site include car parking, picnic areas, toilets, rubbish bins, BBQs, treated water, and a lookout. Camping is not permitted at Cania Dam itself, though accommodation options exist nearby, including a Big4 caravan park approximately four minutes' drive from the boat ramp.

The lake is a stocked fishery managed in part by the Cania Dam Fish Stocking Association, which maintains populations of Australian bass, saratoga, and yellowbelly (golden perch). A Stocked Impoundment Permit (SIP) is required to fish, available through Fisheries Queensland. Onshore fishing on or near the dam wall is not permitted. Paddlers should be aware of fishing activity on the water, particularly given the lake's popularity as a kayak fishing destination.

The combination of clear water, deep channels, and the enclosing granite terrain gives the lake a distinctive character. The multiple arms of the impoundment offer varied paddling routes to explore. Autumn and spring are noted as the best seasons to visit for outdoor activities on the lake. The surrounding Cania Gorge National Park includes hiking trails and scenic lookouts that complement a paddling visit.
