Department officials say algae in the Lincoln Memorial Reflecting Pool resulted from residual material idle in supply lines for eight weeks after U.S. President Donald Trump’s renovation finished on June 14, 2026.
The National Park Service installed a $1.7 million nanobubbler system and a $14.2 million “American Flag Blue” liner, bringing total project cost to over $14 million.
