Lake Champlain contains cold fresh water. Divers should be familiar with diving in cold water environments. Watch your thermal comfort. Monitor your air. It is recommended that you exit the water with a minimum of 500psi.
Visibility can vary greatly on all wrecks on any given day.
Silty bottoms can cause zero visibility situations quickly. Practice good buoyancy control and stay off the bottom. Always build in a safety margin. Caution and good diving practices should prevail at all times. Watch for currents and changing weather conditions.
