Thompsons Creek Dam is a premier trophy trout fishery located in the Blue Mountains region of New South Wales. Managed specifically as a trophy fishery, this dam is renowned for producing consistently large rainbow and brown trout, offering some of the best lake-based fishing for these species in the state. The fishery also supports populations of European perch and tiger trout. Access is restricted to a single entry point, with fishing permitted only during daylight hours, creating a carefully managed angling environment focused on quality over quantity.
