Key elements of a water rescue preplan include clear site information, defined access and staging, identified hazards, and pre-arranged resources and roles. Together, these give crews a common picture of the site and a ready-made framework for command, control, and safe operations.
Site and access information
-
Exact name(s) of the body of water, GPS coordinates, and common local names.
-
Marked access points for personnel and boats, plus alternative launch sites if primary access is blocked.
-
Pre-designated staging areas for apparatus, EMS, and technical rescue resources, including downstream safety positions on moving water.
Hazards and environmental data
-
Known hazards such as currents, hydraulics, strainers, low-head dams, weirs, bridge piers, drop-offs, and underwater obstructions.
-
Seasonal and operational considerations: typical water levels, temperature, ice conditions, flood behaviour, and visibility issues (night, fog, shore vegetation).
Resources, roles, and procedures
-
Required minimum staffing, specialized teams (dive, boat, ice, rope), and mutual-aid or law enforcement partners with contact details.
-
Standard operational templates: incident command location, zones (hot/warm/cold), PPE requirements, downstream safety setup, and preferred rescue options by risk level (reach/throw/boat/entry).
Communications and mapping
-
Radio channels, interoperability plans, and a simple site map showing access routes, launch points, landmarks (bridges, dams), and sectioned areas for search or containment.
-
Checklists for size-up, resource requests, and crew briefings to ensure consistent implementation of the preplan under stress.
