For days, workers have been trying to rid the Reflecting Pool of algae after a more than $14 million renovation that President Donald Trump said was “done properly” and “could last for 100 years.”
But now workers have another problem to contend with: peeling paint. On Thursday, a sheet of the pool’s surface — painted in “American Flag Blue,” a color selected by the president — was seen floating in the water on the north side of the pool. It undulated in the water as curious tourists gathered, some of whom had come to see the green algae.

At 5:35 p.m. on Thursday, a worker came to remove the sheet of pool surface, telling a Washington Post photographer not to photograph it, despite being on public land.

The Interior Department did not immediately respond to questions about the paint and why the pool surface is separating. The agency said in a statement on Wednesday that it is treating the pool with hydrogen peroxide and “high-tech nanobubble ozone technology” to effectively cut off the algae’s food supply.
On Thursday, the Interior Department press office posted on X that “the Reflecting Pool water is crystal clear, and our National Park Service team is now vacuuming up the bottom of some parts of the Reflecting Pool — just like the destroyed Iranian Navy resting on the bottom of the Persian Gulf.”
