A paddle trip downriver can include these river hazards.

• Low-head dams: These structures are difficult to see and can trap boaters. Consult a map of the river before your trip, and know where dams are located. Always carry your craft around them.
• Rapids: When approaching rapids, go ashore well upstream and check them out before continuing. If you see dangerous conditions, carry your craft around them.
• Strainers: These river obstructions allow water to flow through but may block small boats. Strainers may include overhanging branches, logjams, or flooded islands.
