Algae Appears in Renovated Lincoln Memorial Reflecting Pool After Trump‑Era Reopening

The Trump administration promoted the completion of renovations to the Lincoln Memorial Reflecting Pool, claiming the project made Washington, DC "better than ever." The refurbishment cost rose from an initially projected $1.8 million to about $14.2 million, compared with a $35.3 million overhaul under the Obama administration. A state‑of‑the‑art ozone nanobubbler filtration system was installed to keep the water algae‑free.

A day after the pool was refilled, visible algae was observed along the water’s edge. Interior Department spokespersons described the growth as "residual algae" from dormant supply lines and part of the normal startup process, saying workers were clearing it and the nanobubblers would maintain water quality. The White House highlighted the renovation on social media before the water was even added.

Local residents and tourists offered mixed reactions to the new "American flag blue" paint and the algae sighting, with some praising the appearance and others questioning the value of the expenditure. President Donald Trump touted the project as a personal accomplishment, contrasting it with previous administrations.
