It is important for the boat operator to become familiar with where to get local hazard conditions information and not become complacent with his/her knowledge of local hazards; hazards are ever changing in every type of water system (i.e. lakes, ponds, rivers, oceans, etc.). Types of hazards to be discussed should be state specific (i.e. low-head dams, rapids, sudden winds, tides, sand bars, currents, white water, overhead cables, bridges, waves, heavy boating traffic, etc.).
