Overview
The Water Bureau has replaced its original 1894 reservoirs with a new 12.4-million-gallon, seismically reinforced underground reservoir. This reservoir supplies water to Portland's west side and serves more than 360,000 people, including all downtown businesses and residents, 20 schools, 5 hospital complexes, and more than 60 parks.
Currently we are working to install the reflecting pool and interpretive elements, restore historic structures and open the area to the public for the first time in decades. This page last updated February 29.

Monitoring ground movement
Started in February 2022, the Water Bureau replaced some sensors in the park to help us measure ground movement of the slow-moving landslide between the Portland Japanese Gardens and Washington Park Reservoir. We installed some of these a few years back and are replacing them as part of ongoing maintenance. This work ensures that we can gather accurate information about soil movement near the reservoir as part of our seismic planning efforts.
In addition to building new walkways and a reflecting pool, we'll plant native flowers and grasses, making a better habitat for wildlife, including butterflies. When we've completed the final stage, this park will transform into a vibrant public space we all can enjoy.
