We won't put a boat on the river by itself when the combined air and water temperature is under 100 degrees or when the water temperature in the James is under 55 degrees, the Maury 50 degrees. We always reserve the option to move your trip to another if the conditions on your reserved choice are unsafe or the water is too low. We will also move anyone we deem not up to the trip reserved to an easier, safer trip. Remember, the more challenging a trip is, the more opportunity there is for injury or property damage. Customers are responsible for themselves, those in their group, and all personal and rented equipment.
