The Lincoln Memorial Reflecting Pool, recently renovated at a cost of $14 million under the Trump administration, has quickly turned green due to an algae bloom. Despite attempts to paint the pool ‘American flag blue,’ officials state that this algae is a normal occurrence as the pool was reopened. The National Park Service has been working to address the resurgence of the algae, which has become a point of controversy, with some attributing the issue to past administrations. This has sparked reactions from pool owners and the public, questioning the effectiveness of the renovations and highlighting ongoing management challenges in maintaining the historic site.
