Work crews are treating a bright green algae bloom [3] that appeared in the Lincoln Memorial Reflecting Pool on June 16 [2].
The situation draws attention to the maintenance of one of Washington, D.C.'s most visible landmarks and the potential unintended consequences of recent aesthetic changes to the site.
The bloom surfaced shortly after a $14 million [1] renovation project initiated by President Donald Trump. The project involved repainting the bottom of the pool in a shade described as "American flag blue" [1]. This specific color change is linked to the creation of conditions favorable to algae growth [1].
Crews are using hydrogen peroxide to treat the water and remove the growth. The pool is located between the Lincoln Memorial and the Washington Monument, serving as a central point for national gatherings, and tourism.
While some reports suggest the repainting directly caused the bloom, other accounts indicate it remains unclear if the remodel was the primary driver of the growth. Regardless of the cause, the visible green hue has contrasted sharply with the intended blue finish of the pool's floor.
The incident has already drawn commentary from late-night television. Jimmy Kimmel said, "President Trump promised he would drain the swamp. Instead, he spent 14 million of our dollars building a new one."
“Crews are treating a bright green algae bloom that appeared in the Lincoln Memorial Reflecting Pool.”
The emergence of algae following a high-cost aesthetic renovation highlights the tension between symbolic architectural changes and the biological realities of open-water maintenance. Because the pool is a focal point of the National Mall, any failure in the $14 million upkeep project becomes a visible symbol of government inefficiency and a target for political satire.
