A flood barrier for protecting the environment having a venturi type effect pumping means not requiring external power, the flood barrier comprising a wall and a pump for drawing water across the barrier from a first side to a second side. The wall configured to provide a barrier preventing movement of water from the first, drain, side to the second, tributary, side, of that wall. The barrier further comprising a pipe traversing the wall for transferring water between the two sides of the wall the pipe being terminated in the first side of the wall at a venturi effect pump, the pump being feedable with water from the drain through a conduit inlet so as to create suction in the pipe for drawing water through the pipe from the second side of the wall to drain water from the second to the first side of the wall.

An automated water control device comprises a rotatable housing that can be incrementally positioned to control flow of water over an upper or weir edge of the housing. The device is installed at a control point in an impoundment area, such as a settling pond. The housing is selectively rotated to raise and lower the height of the weir edge to a target gate height. Automatic control is provided for operation of the device by a controller communicating with an actuator. A system of the invention includes one or more water control devices and the controller. A method of the invention includes controlling flow of water from an impounded water source by use of the automated water control device. Manual or semi-automated embodiments are also disclosed.
