Inflowing rivers can provide a major driving force for water circulation in lakes in which water turn‐over time is short, that is, less than a few years. Such inflow‐induced currents strongly influence the dispersion and sedimentation of allochthonous particulate matter, especially fine‐grained particles that can remain in suspension in lake water for days or weeks. We present data to illustrate the importance of inflow‐induced circulation on sedimentation patterns in Lake Brienz and Lake Biel, two large lakes in northwestern Switzerland, and suggest that such currents should not be disregarded in sedimentological studies of similar lakes elsewhere.
