1. A water management device configured to drain water from a stormwater pond, the water management device comprising:
a sluice comprising:
a housing defining a chamber, the housing defining a plurality of openings configured to permit the water outside the sluice to enter the chamber; and
a front wall defining a front of the chamber, the front wall defining an aperture configured to permit the water to exit the chamber;
a buoyancy device coupled to the sluice, the buoyancy device configured to bias the sluice towards a top of the water; and
a drainage element pivotably coupled to the sluice, the drainage element configured to receive the water exiting the chamber and direct the water away from the sluice, the drainage element comprising:
a tapered inlet extending along a longitudinal axis, the tapered inlet comprising an input disposed against the aperture of the front wall, an output opposite the input, and sidewalls extending between the input and the output, wherein the sidewalls narrow from the input to the output at an angle between 12 degrees and 30 degrees with respect to the longitudinal axis; and
a channel extending away from the tapered inlet, the channel configured to receive the water from the aperture via the tapered inlet and direct the water away from the sluice.
