What does it mean to divert a river?
Water diversions consist of a system of structures and measures that intercept clear surface water runoff upstream of a project site, transport it around the work area, and discharge it downstream with minimal water quality degradation for either the project construction operations or the construction of the diversion.
What does diverting water mean?
A water diversion is the removal or transfer of water from one watershed to another. The term “consumptive use” is used to define diversions and exports, because the water is being “consumed” without then returning to its source.
Why is diverting water bad?

How do you temporarily divert water?
Temporary diversion methods include temporary diversion channels, pump-arounds, piped diversions, coffer dams and other similar practices. The primary purpose of all temporary diversion methods is to protect water quality by passing upstream flows around the active construction zone.
How do dams redirect water?
Detention dams are built to catch surface runoff to prevent floods and trap sediment by regulating the flow rate of the runoff into channels downstream. Diversion dams are used to raise the water level in order to redirect the water to the designated location.
What does it mean to divert water from a river?
