Every year, people are seriously injured or killed at dams. Most of these accidents could be avoided by simply staying clear of the restricted zones at dams, by understanding the dangers dams can create, and by obeying all warning devices.
Important tips to stay safe
- Always stay a safe distance outside of warning signs, buoys and barriers when fishing, boating or swimming.
- Stay away from the edge of waters above and below hydroelectric stations.
- Be sure to obey all warning signs and signals.
- Stay back from dry riverbeds below dams. They can quickly change into rapidly flowing waterways.
Be alert for the warning signs of rising water:
- Flashing lights, horns, or sirens.
- Increased or changed wildlife activity.
- Louder sound of rushing water.
- Previously exposed rocks or snags are covered with water.
- Clear water quickly becomes cloudy.
- Suddenly faster water currents.
Critical danger zones at dams
- Hazard area marked by buoy lines
- Sudden water discharge from dam gates
- Strong, unpredictable currents above and below dams
- Sudden turbulent discharges from automatically operated power house generators
- Deceiving reverse currents below spillways
- Slippery surfaces on dam structures and shorelines
- Submerged hazards above and below dams
- Open spillways which may not be visible from above the dam
- Debris passing over or through the dam
- Ice that forms near a dam is often thin and unsafe
Don't take chances when boating or canoeing
- Never anchor a boat below a dam. Rapid surges in water levels can pull an anchored boat under water in seconds.
- Beware of dangerous and unseen currents. Backrollers, eddys, and whirlpools can pull a boat upstream into a spillway and quickly capsize it.
- Boating above or below a dam can be very dangerous. Always maintain a safe distance from the dam. Keep your motor running when near a dam so that you are always ready to maneuver or leave the area quickly.
- Stay away from spillways. Changing currents and unpredictable waves make boat control difficult.
