An apparatus or biopassage (A) includes a housing ( 20 ) dimensioned for receipt in a waterway during an increased flow event. The housing has a passage: ( 26 ) that provides a region of reduced flow generally irrespective of the flow external to the passage. A flow disrupter ( 50 ) disturbs laminar flow in the waterway above the passage. A preferred embodiment of the disrupter includes surfaces ( 52, 54 ) disposed in angled relation relative to a common apex ( 60 ) located above a longitudinal opening ( 30 passage. The surfaces include a series of peaks and valleys formed by angled planar portions ( 56 ) in one arrangement. A deflector (NC) is positioned upstream of an inlet end ( 40 ) of the passage to direct water away from the passage.
