Using the diagrams

Rolling your cursor over a dam symbol brings up a box with the current elevation of the water in the dam's reservoir, how that elevation relates to what is called for in the Water Control Diagram, and the amount of water flowing into and out of the reservoir.

Clicking on the dam symbol brings up more detailed water elevation and flow information, including how water levels relate to boat ramp elevations.

The large "cup" to the left (on the Willamette and Rogue diagrams) explains how close that system as a whole is to its Water Control Diagram.

The Corps of Engineers and other agencies collaborate on gathering and analyzing data regarding current and projected future reservoir and river level information.

This information is hosted on the Northwestern Division Water Management site.

The water management mission

Detroit reflection--a historical photo

The Corps plays a major role in a coordinated and complex system to reduce flood risks and provide water for hydropower generation, fish and wildlife enhancement, navigation, recreation and other uses. Portland District's primary water management mission is to save lives and reduce property damage by reducing flood risks with measures both structural (such as dams and levees) and non-structural (such as improving the natural function of floodplains). We also assist communities in developing responses to flood risks and hazards.

As part of this mission, we own and operate 16 dams in Oregon, maintaining these dams with available resources to meet authorized purposes, the foremost of which is public safety. We also assess levees for integrity and viability. No combination of actions can prevent floods and no single agency can manage them.
