How does the southwest border of the district of columbia differ from the capital's three other borders?

Virginia is the states that surround Washington D.C on its southwest side and the states of Maryland on its southeast, northeast and northwest sides; It intersects those states’ shared boundary, which is both the upstream and downstream from the Region of the Potomac River south shore. The part of Potomac River that passes Washington D.C is practically completely within the District’s border, as the Districts outspreads to the bank of the south. The area covers the historic “centralized city”, the country of which was previously part of those two neighboring states prior they respectively surrendered it for the national capital. In 1847, the Congress restored the land that was surrendered from Virginia. So, what was left in the modern state district was particularly once part of Maryland.The geography of the District of Columbia is similar to the substantial geography of much of Maryland. It has three major normal flowing bodies of water: The Potomac River and two side streams, the Anacostia River and Rock Creek. It also includes the Washington Channel that flows into the intersection of the Anacostia and Potomac Rivers. The region has also three man-made lakes: The Mc Millan Reservoir near Howard University; Secondly, The Dalecarlia Reservoir, that crosses over the northwest boundary of the District from Maryland, and the third was Georgetown Reservoir upstream of Georgetown. Lastly, the fourth minor lake is at Fort Reno in Tenleytown.
