The water in the canal comes from the C-111 Canal, which is part of the South Florida Water Management District's canal system. There are no significant tributaries or dams that directly affect the canal. The flow in the canal depends on rainfall and water management activities in the region. The wet season from May to October typically has higher flows, while the dry season from November to April has lower flows. Interesting fact: The South Florida Water Management District manages over 2,100 miles of canals and levees to protect against flooding and provide water for agriculture and drinking water supplies.
