Abstract
A self-regulating device for controlling the flow of water from a conduit open end into a reservoir or wet marshland and to an outside body of water, such as tidal water, which includes a gate pivotally mounted at its bottom edge so as to be pivotable upwardly to close the conduit end. A rod is pivotally connected to the upper edge of the gate and extends upwardly through a slotted bracket, and a float is mounted on the upper portion of the rod above the bracket. As the level of the tidal water rises, the float will rise and move the gate into the closed position.

A device for controlling the flow of water from a conduit open end into a wet marshland or the like and comprising a flow-controlling gate pivotally mounted at its bottom edge upon a horizontal axis in the vicinity of the bottom of the conduit open end, said gate being pivotable upwardly against the conduit opening to a closed position, a bracket extending from above the conduit and having a slot substantially parallel to the longitudinal axis of the conduit, a rod pivotally connected to said gate and extending upwardly through said bracket slot, and a float on said rod above said bracket such that as the level of water adjacent the conduit open end and outside thereof rises, the float will rise to pivot said gate upwardly toward its closed position.
