The Lincoln Memorial should be green with envy: This reflecting pool stayed clear

The Architect of the Capitol has long toiled to keep the Mall’s other body of water from falling into disrepair.

Still blue waters, abundant waterfowl, promenading tourists and barely a whiff of mildew — that is the vision President Donald Trump has struggled to turn into reality this month at the Lincoln Memorial Reflecting Pool.

But that has long been the reality just a mile-and-a-half down the National Mall, where another reflecting pool floats just under Capitol Hill — and under the radar — without a scummy green film floating on top.

As the algae-tinged drama has played out at the Lincoln Memorial, little attention has been paid to its sister pond which is slightly smaller, more obscure and managed by a different entity — the Architect of the Capitol, not the National Park Service.

Both are expensive and challenging to maintain, but the trapezoid-ish Capitol Reflecting Pool hasn’t faced the same intractable problems that have plagued the long and skinny pool to the west.

“Anytime you have a water feature in general … they are beautiful, they’re amazing, but they’re problematic because they degrade faster over time than pretty much anything else you’re going to have,” Architect of the Capitol Thomas Austin said in an interview Wednesday. “They require pumps, require pipes — corrosion, animals, diseases, bacteria, algae. There’s a lot of things that go along with that.”

Austin’s agency drains the Capitol pool each fall and sometimes in the spring to evaluate the basin and make repairs. Employees go in with heavy equipment to “remove the sludge that collects throughout the year,” according to a 2017 AOC report.

Then masons repair cracks and other issues with the concrete basin and plumbers tackle pipe and pump problems before refilling the pool. The draining, repairing and refilling can all happen within a week, depending on the extent of work needed, according to an internal AOC bulletin.

In contrast, draining and refilling the Lincoln Memorial Reflecting Pool typically takes about a month.

There is no evidence that the National Park Service or White House sought the AOC’s expertise with reflecting pool maintenance before embarking on the recent renovations across town, which included spraying the floor with an “American flag blue” rubberized coating.

The Park Service has some experience with the Capitol pond: It managed the body until 2011, when Congress assumed control for itself in an omnibus spending bill — scuttling NPS plans for a shallower pool with an overnight draining system.

Instead, the Architect of the Capitol proceeded with a $7.3 million renovation that included draining the pool, thoroughly cleaning it and making repairs to the concrete.

Today, families of ducks call the Capitol Reflecting Pool home, and AOC craftspeople even fabricated and installed ramps to help ducklings make their way in and out of the water. (Some congressional fiscal hawks briefly balked at the expenditure.)

This week, a trio of dead ducks found at the Lincoln Memorial pool increased scrutiny of the Trump administration’s renovation, including the use of high-concentration hydrogen peroxide in the water to combat a recent algae bloom.

On Thursday, eyewitnesses who posted on social media reported the water appeared closer to sparkling, though some residual algae was spotted.

The White House did not address questions about whether it had consulted with the legislative branch on how to maintain a water body before embarking on the Lincoln Memorial project.

“Today, the Reflecting Pool is crystal clear and is reflecting perfectly,” White House spokesperson Taylor Rogers said in a statement, calling it a feat “only an expert builder like Donald J. Trump could accomplish.”

Austin also declined to weigh in on why the water at the Lincoln Memorial has been so much more troublesome than the Capitol’s.

“I will not say that our full reflecting pool is without problems, because it certainly does have some issues,” he said. “It’s also smaller, so that’s part of it, too. And it was kind of formulated in different ways, so it’s kind of hard to compare apples to apples on this one.”

The Capitol’s pool, sandwiched between two parking lots and the Ulysses S. Grant Memorial was completed in 1971, making it about half the age of the Lincoln Memorial’s. It has not always been without blight, however.

In 2020 there was an algae bloom during a stretch of particularly hot weather. And in 2008, when the pool was still under NPS control, at least two dozen dead ducks were removed from the water after avian botulism took hold. These days, some cracked stone can be spotted along the perimeter.

Several lawmakers who exercise oversight of the Capitol campus declined to say much to compare and contrast the two reflecting pools.

“I want to thank the Architect of the Capitol for keeping it clear and keeping it clean,” Sen. Chris Van Hollen (D-Md.) said in an interview this week when asked if his time on the Legislative Branch Appropriations subcommittee gave him any insight into the pool.

“Size matters,” added Rep. Stephanie Bice (R-Okla.), a member of the House Administration Committee.

Sen. Martin Heinrich (D-N.M.), the top Democrat on the Legislative Branch Appropriations subcommittee, said he believed the Trump administration’s rushed approach to the Lincoln Memorial rehab was the most obvious distinction between the health of the two pools.

“I mean, anybody with an eighth-grade science class could have predicted that this was not going to go well,” he said.
