The reasoning behind removing and retaining dams is often heavily influenced by monetary gains to be made by stakeholders. As represented in the movie, fishermen often support the removal of dams due to the increased habitat quality for many sport species. The bettered environment allows for more fishing opportunities, which lead to increased tourism and monetary gain. The restoration of streams to their natural state has been displayed by a study done on Pine River, which found a substantial amount of time is required, but substrate, water flow, sediment transport, and channel shape all moved towards their natural states (Burroughs). As riverine systems gradually move towards their original states, fish will work their way into the waterways for use of breeding grounds, transportation, and refugee from other system’s disturbances. With these fish come millions of dollars in equipment, services, and the restoration of the environment’s natural state. Monetary gain another large factor in retaining dams. The benefits of dam construction vary depending on location and use of the waterway, as seen in the video. One example was the businesswoman who supported dam retention due to the economic value associated with businesses on the waterway. San Antonio provides a prime example of the money that can be made off stable waterways. Hundreds of restaurants, services, and retailers are located feet from the river, all of which depend on a safe controlled waterway that needs to be properly managed through dam use. Another use of dams is irrigation, as seen by the 2,104 hm3 of water that was released for irrigation over 21 years of the Eleviyan reservoir dam in Iran (Sattari). The benefit of the water allocated to irrigation for farming arguably outweighs any monetary gain, given it provides sustenance for human life. **__ Works Cited __** Burroughs Bryan A., Hayes Daniel B., Klomp Kristi D., Hansen Jonathan F., Mistak Jessica. “Effects of Stronach Dam removal on fluvial geomorphology in the Pine River, Michigan, United States.” __Geomorphology__.
