Width Estimation, Method 3
Choose a baseball size rock. Stand near the stream and throw the rock several times with equal force, ideally about as far as you estimate the river to be wide, stepping off the distance each time. Average your throws. Finally throw the same rock with the same force across the river. Compare your throw of a now known distance to the width of the river. You can also pick a tree on the other shore, than pick a tree that appears to be of equal distance but on your side of the river. Step off the distance to the second tree. These method should yield results that are close enough for most purposes.
