A siphon spillway in a dam is usually not technically a siphon, as it is generally used to drain elevated water levels. [34] However, a siphon spillway operates as an actual siphon if it raises the flow higher than the surface of the source reservoir, as sometimes is the case when used in irrigation.
A siphon spillway uses the difference in height between the intake and the outlet to create the pressure difference required to remove excess water. Siphons require priming to remove air in the bend for them to function, and most siphon spillways are designed to use water to automatically prime the siphon.
A waste weir on a navigable canal is a slatted gate on each canal level or pound, to remove excess water and to drain the canal for repairs or for the winter shutdown. [1] ...
The canal spillway of Laguna Diversion Dam, shown here, uses a baffle chute drop structure to pass water to a lower elevation. Drop structures can be classified into three different basic types: vertical hard basin, grouted sloping boulder, and baffle chute. Each type is built depending on water flow, steepness of the site, and location. [1]
A perforated disc (4) covered by a flexible plate or flap (5) is joined by the siphon rod (6) to the flush lever. Pressing the lever raises the plate, forces water over the top of the siphon into the vertical pipe, and starts the siphonic discharge. Water flows past the flap until the cistern is empty, air enters the siphon and the flush stops.

The Yuma Main Canal continues 10.5 miles (16.9 km) southwest until it reaches the 9.9-foot (3.0 m) Siphon Drop Spillway where a power plant was later built in 1926. After another 3.5 miles (5.6 km), it reaches the Colorado River Siphon which siphons the water under the Colorado River. After it reaches Yuma, it split into the East and West Main ...
