Abstract
A baffle apparatus and method for directing fluid flow to reduce damage to an energy dissipating basin that includes an inlet, an outlet, a floor, a sidewall that extends upward from an edge of the floor, and an opposing sidewall that extends upward from an opposing edge of the floor defining a basin interior with a basin span between the sidewall and the opposing sidewall. The baffle apparatus includes a deflector structure that is generally planar and is fixedly or adjustably positioned substantially transverse to a downstream direction flow in the basin, the deflector structure spanning between the sidewall and the opposing sidewall above the floor. Also included, is a retaining structure for fixedly or adjustably positioning and securing the deflector structure to the sidewall. The deflector structure directs flow in the basin to flow in a downstream direction from a reverse upstream direction adjacent to the basin floor.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
