At every scene a map should be made of the area. This map does not have to be elaborate, but it must entail all landmarks and last seen points. Place on the map the name and location of each individual witness. Have the location of the command post, staging area, entry and exit points. Show all areas searched and type of patterns used. This map does not have to have bottom contours and obstacles as do the maps that should be made during preplanning, but should have at least one or two underwater landmarks for future reference.
When the victim is found transfer this location to the point on the map giving distance from shore, depth of water, and body position. If the victim was caught in trees, or other would be hazards, mark this on the map. Give exact compass bearing as to location so that the exact spot can be found again if needed.
When the search teams abandon an area, or calls off a search, a map must still be made showing all areas searched. Be sure on all maps to record weather, time of day, and when searching started and ended, as well as all Team members present.
