Artificial reduction of stream discharge resulted in an increase in benthic invertebrates in the drift. Virtually all bottom—dwelling forms were affected. Entry into the drift seemed an active process initiated by changes in current velocity and depth, and resulting in reversal of the normal avoidance response to light.
