I have been hearing about this dam removal for years. The bureaucrats don't like the concept because it might catch on. Here in northern California we have a stream called Alameda Creek which empties into the San Francisco Bay at the south end. Old timers dammed, diverted and wiered this little thing to death, yet the steelhead kept coming back. Although in dwindling numbers. Finally, it looks like they are going to remove some of the lower barriers.
The problem with dam removal is the silt that builds up behind them over the years. Removal has to be a slow process or you will wipe out the river below the dam. As I heard it they plan to "notch" the dam and let the silt disburse more slowly. One can only hope that once the process begins budgets and bureaucrats will allow the completion.
