Please answer the following question: Information: - Fresh water is naturally occurring water on Earth's surface in ice sheets, ice caps, glaciers, icebergs, bogs, ponds, lakes, rivers and streams, and underground as groundwater in aquifers and underground streams. Fresh water is generally characterized by having low concentrations of dissolved salts and other total dissolved solids. The term specifically excludes seawater and brackish water although it does include mineral-rich waters such as chalybeate springs. The term "sweet water" (from Spanish "agua dulce") has been used to describe fresh water in contrast to salt water. The term fresh water does not have the same meaning as potable water. Much of the surface fresh water and ground water is unsuitable for drinking without some form of purification because of the presence of chemical or biological contaminants. - State Highway 66 or SH 66 is a state highway running from Garland to Greenville , roughly parallel to Interstate 30 . Along the way , it passes through Rowlett , Rockwall , Fate , Royse City , and Caddo Mills . It also twice crosses Lake Ray Hubbard . - Lake Ray Hubbard, formerly Forney Lake, is a fresh water impoundment (reservoir) located in Dallas, Texas in the counties of Dallas, Kaufman, Collin, and Rockwall just north of the City of Forney. It was created by the construction of the Rockwall-Forney Dam which impounded the East Fork Trinity River. - A reservoir (etymology: from French "reservoir" a "storehouse" ) is a storage space for fluids. These fluids may be water, hydrocarbons or gas. A reservoir usually means an enlarged natural or artificial lake, storage pond or impoundment created using a dam or lock to store water. Reservoirs can be created by controlling a stream that drains an existing body of water. They can also be constructed in river valleys using a dam. Alternately, a reservoir can be built by excavating flat ground and/or constructing retaining walls and levees.
