That is smart..........smart water.........
he basin is designed to release 250 million US gallons (950,000 m3) of water captured at high tide twice a day. The inlet gates, located on the Potomac side of the basin, allow water to enter the basin during high tide. During this time, the outlet gates, on the Washington Channel side, close to store incoming water and block the flow of water andsediment into the channel. As the tide begins to ebb, the general outflow of water from the basin forces the inlet gates to close. This same force is applied to the outlet gates, which open into the channel. Silt build up is swept away by the extra force of water running from the Tidal Basin through the channel. The gates are maintained as navigable by the U.S. Army Corps of Engineers, which has recently completed a project to restore the functioning of the gates.
The northern lobe of the basin is crossed by the 433 foot (132.0 m) Kutz Memorial Bridge, named in honor of Brigadier General Charles W. Kutz the Commissioner of Engineering for the District of Columbia during the first half of the 20th century, carrying eastbound Independence Avenue traffic in three lanes. The bridge was designed by Paul Cret, begun in 1941, completed 1943 and altered with dedication in 1954. It is of concrete and steel on pilings, all granite faced.[1]
