Reflective pool is filling up!

If you're referring to the Lincoln Memorial Reflecting Pool, it has undergone several major changes since it was built in 1922-1923:Original construction (1922-1923)* Built between the Lincoln Memorial and the Washington Monument.
* Designed as a long, shallow pool to reflect the monuments and sky. Repairs in the 1980s* The pool had begun sinking into the marshy ground beneath it and developed leaks.
* Concrete repairs were made, but the underlying structural problems remained. Major reconstruction (2010-2012)This was the largest overhaul in its history:* The pool was completely drained.
* Nearly all of the old structure was removed.
* More than 2,100 timber pilings were driven into the ground to stop further sinking.
* A modern circulation and filtration system was added.
* New walking paths were built around the pool.
* The bottom was modified to improve reflections. The project cost about $30-35 million. Later maintenance* 2012: Shortly after reopening, algae blooms required draining and cleaning.
* 2015-2016: Repairs were made to part of the basin after construction damage.
* 2017: The pool was drained to address a parasite outbreak affecting ducks. 2026 renovation* The pool was drained again.
* Leaks were repaired and the bottom was waterproofed.
* The interior surface was resurfaced and coated in a dark blue color described as "American flag blue."
* The project cost about $14 million. Ongoing issue: algaeOne thing that has not completely gone away over the years is algae growth. The pool experienced algae problems after the 2012 reconstruction and again shortly after the 2026 renovation, requiring additional treatment and cleaning. Should the money have been spent each time. I think so. But I wouldn't be giving money to all the states with their hands always open wide asking for money. Maintain ourFederal Government assets.
