Reservoir 5 (1911) is one of three open water reservoirs at Mount Tabor Park and of five total in Portland. Mount Tabor's three open reservoirs and their ancillary structures were placed in the National Register of Historic Places on January 15, 2004. The Environmental Protection Agency (EPA) regulation known as the Long Term 2 Enhanced Surface Water Treatment Rule (aka the LT2 Rule) imposes new requirements that open water reservoirs be covered, buried or additionally treated. This applies to Portland's five open reservoirs and to the unfiltered Bull Run source supplying them. In 2016, all of the open reservoirs at Mount Tabor were finally taken offline and permanently disconnected from Portland’s drinking water system.
