Karkarook Lake, part of the 40-hectare Karkarook Park near Moorabbin in Melbourne's southeast, is a designated Family Fishing Lake listed by the Victorian Fisheries Authority.

The artificial wetland is stocked with rainbow trout fingerlings, particularly during school holiday programs, and also holds redfin, eels, carp, estuary perch, and Murray cod. Two fishing jetties are accessible from the Lake Walk path that circles the water.

The first jetty, near a picnic shelter, is reached via a gentle asphalt path and features a large T-section platform. A second jetty sits three-quarters of the way around the lake on a steeper access path.

A small concrete boat ramp and loading jetty near the Sheoak Picnic Area allow canoe and small-boat launching. The park promotes catch-and-release practices to support the lake's long-term fishery.
