Officials to drain Lincoln Memorial reflecting pool

(AP) -- Officials in Washington plan to begin draining the Lincoln Memorial's reflecting pool for an annual cleaning.

National Park Service spokesman Mike Litterst said in a statement that the draining is expected to begin Friday and the work is expected to take between 30 and 60 days.

The National Park Service says the reflecting pool is more than 150 wide and over 2,000 feet long and contains 6.7 million gallons of water.
