The removal of the Gorge Dam on the Cuyahoga River is in sight, as toxic sediment is to be taken to a former dump off Peck Road in Akron. Site prep for Gorge Dam sediment disposal may start this month
Officials gave an update on the removal of the Gorge Dam in Cuyahoga Falls, announcing the US EPA has cleared $100 million to remove toxic sediment.
There are several ways dams can be removed and the chosen method will depend on many factors. The size and type of the dam, the amount of sediment behind the dam, the aquatic environment below the dam, who owns the dam and what their priorities are, and the timeframe of dam removal are all factors that affect how the dam will be removed.

From the sediment-filled Matilija Dam to the seismically unsafe Potter Valley Project complex on the North Coast, momentum around removing dams that do more harm than good is growing.
The physical process of sedimentation (the act of depositing sediment) has applications in water treatment, whereby gravity acts to remove suspended solids from water. [1] Solid particles entrained by the turbulence of moving water may be removed naturally by sedimentation in the still water of lakes and oceans.
Pumps being used to dewater a spillway at Baldhill Dam. Dewatering / d iː ˈ w ɔː t ər ɪ ŋ / is the removal of water from a location. This may be done by wet classification, centrifugation, filtration, or similar solid-liquid separation processes, such as removal of residual liquid from a filter cake by a filter press as part of various industrial processes.
Sediment discharge into a reservoir formed by a dam forms a reservoir delta. This delta will fill the basin, and eventually, either the reservoir will need to be dredged or the dam will need to be removed. Knowledge of sediment transport can be used to properly plan to extend the life of a dam.
The largest dam removal project in U.S. history has freed the Klamath River, ... The emptying of the reservoirs has released vast amounts of sediment that had accumulated behind the dams, sending ...
