Lake Havasu stretches approximately 45 miles from the Davis Dam at Laughlin, Nevada in the north to Parker Dam on the south end. The main navigable length that most Lake Havasu City boaters use runs about 25-30 miles from the London Bridge area north toward Topock. The lake averages 2-4 miles wide in the main channel. A full lake cruise from the city south to Parker Dam takes roughly 1.5 to 2 hours at moderate speed.
