Claim 7:
8. The skimming system of claim 7, wherein if the flow of water incident on the dual weir door assembly has a medium flow velocity that is greater than said relatively low flow velocity and less than said relatively high flow velocity, the angular degrees to which the first and second weir doors rotate about the common axis of rotation depend on whether there is an ebb in the medium flow velocity or an increase in the medium flow velocity, wherein an ebb in the medium flow velocity causes the second weir door to rotate about the common axis of rotation to an angular degree that places the second weir door in an open position in which the second weir door performs skimming and causes the angular degree to which the first weir door rotates about the common axis of rotation to cause the first weir door to remain in a closed position in which the first weir door does not perform skimming, wherein an increase in the medium flow velocity causes the first and second weir doors to rotate about the common axis of rotation to respective angular degrees that place the first and second weir doors in open positions in which the first and second weir doors perform skimming.
