Final answer:
Boat operators should prioritize safety and environmental protection when traveling under a bridge, especially after heavy rains have swollen rivers.
Step-by-step explanation:
When traveling under a bridge, boat operators should prioritize safety and take into account various factors such as current weather conditions, water levels, and navigational rules. If heavy rains up-country have swollen the river and created foam, it is crucial to wait until the waters subside to ensure safe passage. Transport via trailered boats requires attention to environmental protection; removing any plants, animals, mud, and debris can help protect local waters from invasive species.
While traversing waterways, knowledge of the safest parts of the river is essential. When paddling upstream, it is recommended to stay close to the shore where the current is milder, whereas moving downstream, staying towards the middle can be safer where the flow is more controlled and less obstructive. Also, understanding the risks and navigating these challenges is critical when operating any water-bound vessel.
Boat operators must also be mindful of their impact on the environment. Actions such as draining live wells, bilge areas, and coolers and rinsing equipment effectively are recommended to protect Maryland waters, according to conservation guidelines. It is essential to maintain the health and safety of the waterways for all who use them, including fisherman, recreational boaters, and the aquatic ecosystem itself.
