A "River Flotilla" refers to a group of boats or ships that travel together on a river. This can include various types of vessels, such as barges, canoes, or even larger ships, depending on the river's size and the purpose of the flotilla. Flotillas are often organized for events, celebrations, or specific activities like fishing or tourism. These gatherings can serve multiple purposes, including promoting local culture, enhancing tourism, or facilitating trade. River flotillas can also be a way to raise awareness about environmental issues affecting rivers, such as pollution or habitat preservation, engaging communities in conservation efforts.
