To avoid capsizing, strikes, and deaths, US boaters should actively reconnoiter the dangers beforehand shallow bars, submerged logs, and unexpected currents are taking hundreds of lives annually. The law requires due diligence prior to launching, Coast Guard and state.
Pre-Trip Chart and App Research: Download NOAA charts (free apps such as Navionics, Aqua Map) of shoals, rocks, dams. Look at USGS gauges of river level; declining water is showing bars. Recent snags have been reported on the local marinas.
Visual Scouting on Shore: Parallel drive routes: checking: standing waves (currents), strainers (downed trees), boils (upstream hazards). Glass serene patches – debris lines give signals of currents. Note dam portages.
Slow On-Water Reconnaissance: 1. Idle at no-wake upstream. Glance backwards to find succeeding waves (follows deep water). Spare paddle pole shallows. Record the positions of rocks/logs on the mark GPS.
Local Knowledge Necessary: Marinas, tackle shops, liveries offer up-to-date information a daily change in sands due to floods. Flotillas and auxiliary USCG post waterway conditions.
Legal Responsibilities: Federal Navigation Rules stipulate the right-of-way concession, safety in speed, and collision prevention. PDs, sound signals, navigation lights are required by the state boating laws. Information Report new hazards to Corps of Engineers within 24 hours.
Emergency Hazard Avoidance: Standing waves? Ferry perpendicular. Strainer ahead? above plough, Under submerge paddle. Spill? Deploy throwable.
The tides, floods, storms daily change waterways–scout meekly, boat guardedly. Knowledge of the local is better than charts.
