Devices, apparatus, systems and methods for preventing backflow current problems which often have caused debris and litter to pass out of screen type baskets used in storm water treatment systems. A half size or full size pivoting panel at the input end of a basket screen system placed in a storm water treatment chamber can downwardly divert incoming storm water so as to prevent back flow currents from being formed. The pivoting panel can work well during high flow conditions. A half size or full size pylon located in the input end of the basket screen can split and divert incoming storm water to also prevent back flow currents from also being formed. The pylon can work well during low flow conditions. Also, both the half pivoting panel and the half pylon can both be used at the input end of the screen basket. Still furthermore a gap in the floor before the input end of the screen basket can allow for sediment coming to pass down and collect beneath the screen basket.
