List of reservoirs in Portland, Oregon

The city of Portland, Oregon, is known for having a large number of man-made reservoirs.

Portland's reservoirs provide storage for drinking water from the Bull Run River. Portland is currently in the process of covering some of these reservoirs for continued use due to health concerns, but plans to keep most of them uncovered for their historic and cultural significance to Portlanders. These reservoirs are common for photography and art and are generally located in areas with panoramic views due to the need for them to be elevated.^[1]
