On December 31, 2012, National Park Rangers, using their personal funds and time, lit over 2,000 candles around the reflecting pool in commemoration of the 150th anniversary of the Emancipation Proclamation, where the Park Service rang in the New Year with a Night Watch and Freedom Vigil and the singing of ' My Country, 'Tis of Thee.'.As of 2012, the restoration project was completed and the pool was reopened on August 31.Notable speakers included Alveda King, the niece of Martin Luther King Jr., former vice presidential candidate Sarah Palin, and the event's organizer Glenn Beck.

More than 80 ducks and ducklings have died at the pool due to parasitical infection since May 20. The parasite, which causes swimmer's itch, infects snails which inhabit the pool. The Reflecting Pool was completely drained in June 2017 to control a parasitical outbreak. NPS workers closed the eastern 30 feet (9 meters) of the pool in August 2015 to repair the basin, work that was completed in the summer of 2016. In 2013, construction on the National World War II Memorial damaged the eastern end of the Reflecting Pool. Using an ozone disinfectant system installed during the renovation, the National Park Service said it would double the amount of algae-killing ozone in the pool to control future outbreaks. The algae growth was so extensive it almost completely covered the surface of the pool. Within weeks of the pool's reopening in 2012, it had to be drained and cleaned at a cost of $100,000 due to algae in the pool. The project was managed by the Louis Berger Group. In May 2011, workers began sinking the first of 2,113 wood pilings into a 40-foot-deep (12-meter) layer of soft, marshy river clay and some dredged material atop bedrock to support a new pool. Construction on the 18-month, $30.74 million project began in November 2010. Paved walking paths were added to the north and south sides of the pool to replace worn grass and to prevent further erosion. The pool's water supply system was updated to eliminate stagnant water by circulating water from the Tidal Basin the pool was formerly filled using potable water from the city. Using funding from the American Recovery and Reinvestment Act of 2009, the National Park Service reconstructed the Lincoln Memorial Reflecting Pool.

It has a depth of approximately 18 in (46 cm) on the sides and 30 in (76 cm) in the center. The perimeter of the pool is therefore 4,392 feet (1,339 meters 13⁄ 16 mile) around. It is approximately 2,030 feet (620 m 3⁄ 8 mi) long and 167 feet (51 m) wide. The Lincoln Memorial Reflecting Pool was designed by Henry Bacon, and was constructed in 19, following the dedication of the Lincoln Memorial. Depending on the viewer's vantage point, it dramatically reflects the Washington Monument, the Lincoln Memorial, the Mall's trees, and/or the expansive sky. It is lined by walking paths and shade trees on both sides. Part of the iconic image of Washington, D.C., the reflecting pool hosts many of the 24 million visitors who visit the National Mall annually. It is a long and large rectangular pool located on the National Mall, directly east of the Lincoln Memorial, with the Washington Monument to the east of the reflecting pool. The Lincoln Memorial Reflecting Pool is the largest of the many reflecting pools in Washington, D.C.
