The paper reviews the methodology of attempts to assess the importance of washout as a cause of loss of salmonid eggs and alevins. The results of this study are presented of various small-scale field trials using buried artificial salmonid eggs and tethered table tennis balls. The results suggested that, even when few eggs were actually lost by washout, some downstream movement of the upper layers of gravel and of artificial eggs might have taken place.
