• a horizontally adjustable gate in a frame, the horizontally adjustable gate actuated by an actuator, the horizontally gate in the frame defining a horizontally adjustable opening;
• a vertically adjustable gate coupled by a flexible joint to a first end of a control lever, a second end of the control lever coupled to a float, the vertically adjustable gate defining a vertically adjustable opening;
• the control lever being disposed in a slot of a frame;
• and
• the control lever and frame being configured such that if the float is lowered to the frame the control lever raises the vertically adjustable gate;
• wherein the horizontally adjustable opening and the vertically adjustable opening align sufficiently that water may pass through the horizontally adjustable opening and the vertically adjustable opening, and
• wherein the horizontally adjustable gate is disposed close to the vertically adjustable gate.
