NPS wrote in a sign posted outside the Reflecting Pool that more than half of the 58 supply ports were “deemed nonfunctioning” due to buildup and needed to be cleared. The posting blamed the clogged lines on “years of neglect by previous administrations,” echoing attempts by President Donald Trump to pin the Reflecting Pool’s ongoing troubles on his predecessors. Leaks and cracks in the piping have long afflicted the pool, which was constructed in the 1920s. The administration’s spring renovation, however, was limited to repainting the bottom of the pool and installing a new filtration system, leaving the pipes untouched. The Department of Interior provided a similar explanation when algae first discolored the pool, saying it was residual growth from reactivated supply lines.
