Interior says Reflecting Pool is crystal clear—photos don’t match

The Trump administration claimed the Lincoln Memorial Reflecting Pool was painted blue and then cleared algae plaguing the reopening. But on Wednesday afternoon, observers described the water as green and covered with visible algae, even as the Department of t

Washington’s Lincoln Memorial Reflecting Pool was supposed to look like a calm, blue backdrop. Instead, on Wednesday afternoon, it looked more like a shallow bowl of green water—algae-brown and streaked in a way that didn’t match the “American flag blue” promise painted onto the bottom.

The episode landed at the heart of the Trump administration’s broader capital-city makeover. with President Donald Trump’s team claiming the Reflecting Pool had been painted blue. The explanation that followed was blunt: leftover algae in the pipes. This week. Department of the Interior workers moved in with equipment meant to kill and remove it. using nanobubblers. vacuums. and hydrogen peroxide.

Late Wednesday, the Department of the Interior declared victory in a post shared on social media. “The Reflecting Pool water is crystal clear. and our National Park Service team is now vacuuming up the dead algae resting on the bottom of some parts of the Reflecting Pool. ” the agency said. It added a sharp flourish to the message. comparing what was happening to “the destroyed Iranian Navy resting on the bottom of the Persian Gulf.” The agency went further. claiming the pool was now “so ‘blue’ that the Fake News Media. which has been staked out at the Reflecting Pool for weeks. has fled!”.

But when the water was seen from different angles earlier that day, it didn’t read as blue. From a low angle. the Reflecting Pool could reflect the sky and appear blue—matching the kind of photos the administration shared on Wednesday. Yet the side view told a different story. Up close. observers said they could see bits of algae floating on the surface. and they described it as impossible to see the “American flag blue” painted on the bottom beneath a layer of green plant matter.

As the day unfolded, the contrast wasn’t theoretical. HuffPost reported it had been at the Reflecting Pool on Wednesday afternoon and described ducklings paddling in the water, right alongside the visible algae.

The cleaning effort also raised a broader question about how the pool’s recent algae bloom formed. An analysis of satellite imagery suggests the bloom is its worst in years, the Washington Post reported Thursday. Experts have speculated that painting the surface dark blue may have helped the algae by making the water warmer on hot sunny days.

The Department of the Interior’s victory post came after the nanobubbler technology was rolled out, with Interior workers saying the Reflecting Pool’s algae problem had been tackled most recently after the pool’s reopening—most infamously after Obama’s reopening in a cycle that dates back to 1922.

Still. the sequence of claims and what was visible to the eye left a clear mismatch: a federal agency declaring “crystal clear” water and a painted-blue look. while what could be seen earlier in the day—along with descriptions of floating algae and green surface scum—suggested the pool was not “American flag blue” in any straightforward way.
