Dredge No. 4 (Hän: Lëzrą Kä̀nëchà "s/he is looking for money") is a wooden-hulled bucketline sluice dredge that mined placer gold on the Yukon River from 1913 until 1959. It is now located along Bonanza Creek Road 13 kilometres (8.1 mi) south of the Klondike Highway^[1] near Dawson City, Yukon, where it is preserved as one of the National Historic Sites of Canada. It is the largest wooden-hulled dredge in North America.^[2]

With its 72 large buckets, the dredge excavated gravel at the rate of 22 buckets per minute, processing 18,000 cubic yards (14,000 m³) of material per day. It was in use from late April or early May until late November each season, and sometimes throughout winter. During its operational lifetime, it captured nine tons of gold.
