Best for advanced divers, 4-31m, shore entry, mild current.
Lake Chelan Monument is a freshwater wall and wreck site offering depths between 4 and 31 metres. The site is accessed via a shore entry with on-site parking. Divers encounter visibility ranging from 15 to 70 metres, allowing for clear observation of the wall structure and the deeper wreck. A thermocline exists, with warmer surface waters mixing to 30 metres in summer, while fall and winter bring cooling throughout the depths. The site features mild currents, though the significant depth requires advanced buoyancy control and careful gas management. Due to cold water and depth, appropriate thermal protection is essential, and divers should monitor their depth to mitigate nitrogen narcosis risks.
