Measure speed of the water current prior to entering water as follows: a. b. c. Position two personnel (or objects) at least 100 feet apart near the stream bank. (Position at entry point is A and position 100 feet downstream is point B.) Toss in any object which will float to point B. Measure the time it takes the floating object to go from point A to point B. When object takes less than 35 seconds, stream is too fast — DO NOT ENTER WATER. d. Test the stream near the bank, along the edges of the stream, and in the middle of the stream. NOTE The maximum speed of the wa- ter in which the carrier can safe- ly cross depends on such factors as water choppiness, amount of ice or other debris, overhanging tree limbs, underwater obstacles and the maximum acceptable downstream drift distance. 3. Water must be from of ice and debris. Use the terrain and water obstacle limits below before entering the water.
