1. A storm water filter box having a floatable skimmer apparatus for preventing floatable debris from entering the filter box outlet comprising: a housing chamber having an inlet thereinto and an outlet therefrom; a skimmer panel having a top and a bottom and being positioned in said housing chamber between the inlet and outlet of said housing chamber, said skimmer panel being movably mounted in said housing chamber in a pair of skimmer tracks for movement therein and positioned in said housing chamber to form a channel under said skimmer panel, said skimmer panel having a niche formed therein along the top thereof; and at least one floatation member mounted in said skimmer panel niche on the inlet side of said skimmer panel and being spaced from said skimmer panel to allow water in said housing chamber between said floatation member and said skimmer panel to raise and lower said skimmer panel in said skimmer track with the rise and fall of storm water in said housing chamber to thereby hold the top of said skimmer panel above the water level in said housing chamber; whereby storm water is forced under the bottom of said floatable skimmer panel while blocking floatable debris from entering said housing chamber outlet.
