Definitions of Water Quality Designations

The RiverCast Water Quality Designations provide recommendations about the suitability of the river for various recreational activities based upon predicted levels of bacteria in the river at a given time. The suitability of the water depends upon the type of recreational activity and the extent of contact with the water.

Direct contact recreation is also called "primary" contact recreation by state and federal authorities. As shown in the table below, primary contact recreation includes any activity that is likely to cause immersion in the water and includes jet skiing, swimming, kayaking, wading, and water skiing.

Secondary contact recreation is not likely to cause immersion in the water and is therefore less impacted by changes in water quality. Secondary contact includes but is not limited to rowing, power boating, and fishing.

The table below provides a summary of RiverCast Water Quality Designations as they relate to specific recreational activities.
