• a vent at the bottom wall of said channel forward of said rear wall for allowing water to flow out of said channel;
• the improvement comprising:
• an adjustable flow splitter consisting of a generally V-shaped member extending generally transversely across said channel with the apex of the V forming a trailing edge of said vent and the sides of the V extending rearwardly;
• an adjustable vent plate extending transversely across said channel generally paralleling the apex of said V-shaped member and defining a leading edge of said vent;
• means for adjusting the position of said V-shaped member, thereby controlling the flow pattern of water at said vent;
• and
• means for adjusting the position of said vent plate. thereby controlling the size of said vent.
