The new Lincoln Memorial Reflecting Pool has turned into a hazard for ducks, with algae overtaking the water and at least one duck found dead.
Comparing the pool's condition before and after the renovation, the earlier state, though rough, was far better for the birds.
Now, algae covers the surface, potentially toxic cyanobacteria that can kill animals that skim the water.
The pool's cost has escalated from an initial $13 million to $16 million of taxpayer money.
Former President Donald Trump has blamed vandals for the mess, but critics say the installation work is to blame.
As the nation approaches its 250th birthday, the Reflecting Pool is in disarray, the White House resembles a construction site, and the National Mall's grass has been damaged.
