Lincoln Memorial Reflecting Pool’s Blue Paint Peels After Algae Cleanup Post-Renovation

Blue paint is peeling from the bottom of the Lincoln Memorial’s Reflecting Pool in Washington, D.C., according to a June 20, 2026, report from UPI. The deterioration follows a recent renovation and a cleaning operation intended to remove algae from the basin.

Why is the paint peeling?

The peeling occurred weeks after workers completed a renovation of the pool’s interior. According to UPI, the blue coating applied to the bottom of the structure began to detach following efforts to clean algae from the water.

The Reflecting Pool is a long rectangular basin located on the National Mall between the Lincoln Memorial and the Washington Monument. It is managed by the National Park Service.

What is the impact on the site?

The loss of the blue coating affects the visual appearance of the basin’s floor. The pool is a primary site for national ceremonies, public demonstrations, and tourism in the U.S. capital.

Algae growth has been a recurring maintenance challenge for the basin. The current paint failure follows a specific attempt to resolve these biological growths shortly after the site’s renovation.
