1. A skimming system for skimming an artificial body of water, the system comprising:
a skimmer body configured to be installed in the artificial body of water, the skimmer body having a front entrance for receiving a flow of water of the artificial body of water into an interior of the skimmer body; and
a multi-weir door assembly mechanically coupled to the skimmer body near the front entrance such that the flow of water received in the front entrance is incident on a front side of the multi-weir door assembly, the multi-weir door assembly comprising multiple weir doors that are rotationally coupled to the skimmer body by at least a first hinge assembly, each of the weir doors having a respective buoyancy, and wherein at least first and second weir doors of said multiple weir doors have first and second buoyancies that are different from one another such that the flow of water incident on the multi-weir door assembly affects the first and second weir doors differently in terms of an angular degree to which the incident flow of water causes the first and second weir doors to rotate about first and second axes of rotation, respectively.
 
14. A method for skimming an artificial body of water, the method comprising:
receiving a flow of water of the artificial body of water into an interior of a skimmer body of a skimming system through a front entrance of the skimmer body, wherein the skimmer body is installed in the artificial body of water and the multi-weir door assembly is mechanically coupled to the skimmer body near the front entrance such that the flow of water received in the front entrance is incident on a front side of the multi-weir door assembly; and
performing skimming with the multi-weir door assembly, the multi-weir door assembly comprising multiple weir doors that are rotationally coupled to the skimmer body by at least a first hinge assembly, each of the weir doors having a respective buoyancy, and wherein at least first and second weir doors of said multiple weir doors have first and second buoyancies that are different from one another such that the flow of water incident on the multi-weir door assembly affects the first and second weir doors differently in terms of an angular degree to which the incident flow of water causes the first and second weir doors to rotate about first and second axes of rotation, respectively.
