A lid sealingly closes the open top of the box. There is an inlet at the first end of the box and an outlet at the second end of the box, the outlet extending upwardly to a point vertically above the top of the box to create a backpressure to keep the box full. A plurality of sampling surfaces are removably mounted inside the box for accumulating plant and/or animal specimens from the water flowing through the box.
