Wetlands...
When the North Anna nuclear power plant was constructed in Virginia, the decision was taken to dam the North Anna River to build a massive artificial lake to serve as the ultimate heat sink. The dam proper can generate hydropower, at least enough to serve as the emergency backup supply for the plant.
This created an outstanding wildlife habitat, reduced the visual signature of the site, and created a beautiful set of lakefront communities and recreational areas.
Granted that trick won't work everywhere, but it is a truly lovely solution where it can be implemented
