Boating is allowed on three of Denver Parks & Recreation lakes: Sloan’s Lake, Berkeley Lake in northwest Denver and Smith Lake in Washington Park. Sloan’s Lake allows boats longer than 12’, motorized boats with a maximum of 330 horsepower and allows water skiing. The length limit on the other two lakes is 12’. Sailing, canoeing, rowing and kayaking are allowed on all three lakes. A permit is required to launch any boat on a Denver lake, and the permit sticker must be displayed on the right side of the boat.
