Lake Norman
Lake Norman is an artificial fresh water lake in southwest North Carolina. The largest lake in the state, it was created between 1959 and 1964 as part of the construction of the Cowans Ford Dam by Duke Energy. Located in Iredell County, 15 miles north of Charlotte, Lake Norman State Park boasts the region's popular mountain biking trail system. Geography Lake Norman has of shoreline and a surface area of more than . It is fed by the Catawba River, and drains into Mountain Island Lake to the south. Named after former Duke Power president Norman Atwater Cocke, the lake is sometimes referred to as the "inland sea" of North Carolina. Its normal full level is above mean sea level. Interstate 77 and North Carolina Highway 150 cross Lake Norman at different points. Hydroelectrical power Lake Norman provides electricity to the Piedmont region of the Carolinas. It powers the generators at the hydroelectric station at Cowans Ford Dam, is used by the coal-fired Marshall Steam Station, ...

Catawba County, North Carolina
Catawba County ( ) is a county in the U.S. state of North Carolina. As of the 2020 census, the population was 160,610. Its county seat is Newton, and its largest community is Hickory. The county is part of the Hickory-Lenoir-Morganton, NC Metropolitan Statistical Area. History Catawba County, formed in 1842 from Lincoln County, was named after the Catawba River. The word "catawba" is rooted in the Choctaw sound ''kat'a pa'', loosely translated as "to divide or separate, to break." However, scholars are fairly certain that this word was imposed from outside. The Native Americans who once inhabited the region known as the Catawba people, were considered one of the most powerful Southeastern Siouan-speaking tribes in the Carolina Piedmont. They now live along the border of North Carolina, near the city of Rock Hill, South Carolina. Scots-Irish and German colonial immigrants first settled in the Catawba River valley in the mid-18th century. An official history of the Sc ...

Piedmont (United States)
The Piedmont ( ) is a plateau region located in the Eastern United States. It is situated between the Atlantic Plain and the Blue Ridge Mountains, stretching from New York in the north to central Alabama in the south. The Piedmont Province is a physiographic province of the larger Appalachian Highlands physiographic division and consists of the Piedmont Upland, and the Piedmont Lowlands sections. The Atlantic Seaboard Fall Line marks the Piedmont's eastern boundary with the Coastal Plain. To the west, it is mostly bounded by the Blue Ridge Mountains, the easternmost range of the Appalachians. The width of the Piedmont varies, being quite narrow above the Delaware River but nearly 300 miles (475 km) wide in North Carolina. The Piedmont's area is approximately . The French word ''Piedmont'' (modern spelling ''Piémont'') comes from the Italian , from Latin , meaning " foothill" or, literally, "at the foot of the mountains"; it is the name of the northwestern Italia ...

Stormwater Runoff
Surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to '' channel runoff'' (or ''stream flow''). It occurs when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or human-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry human-made cont ...

Metamorphic
Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock (protolith) is subjected to temperatures greater than and, often, elevated pressure of or more, causing profound physical or chemical changes. During this process, the rock remains mostly in the solid state, but gradually recrystallizes to a new texture or mineral composition. The protolith may be an igneous, sedimentary, or existing metamorphic rock. Metamorphic rocks make up a large part of the Earth's crust and form 12% of the Earth's land surface. They are classified by their protolith, their chemical and mineral makeup, and their texture. They may be formed simply by being deeply buried beneath the Earth's surface, where they are subject to high temperatures and the great pressure of the rock layers above. They can also form from tectonic processes such as continental collisions, which cause horizontal pressure, friction, and distort ...

Igneous
Igneous rock ( ), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rocks are formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Solidification into rock occurs either below the surface as intrusive rocks or on the surface as extrusive rocks. Igneous rock may form with crystallization to form granular, crystalline rocks, or without crystallization to form natural glasses. Igneous rocks occur in a wide range of geological settings: shields, platforms, orogens, basins, large igneous provinces, extended crust and oceanic crust. Geological significance Igneous and metamorphic rocks make up 90–95% of the top of the Earth's crust by volume. Igneous rocks ...

Lake Norman In Ramsey Creek Park
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a depression (geology), basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions ...
