A USGS stream gauge on the creek near Richwood recorded a mean annual discharge of 233.6 cu ft/s (6.61 m 3 /s) during water years 1945-2019. The highest annual mean discharge during the period was 318 cu ft/s (9.0 m 3 /s) in water year 1979, and the lowest was 126.2 cu ft/s (3.57 m 3 /s) in water year 1999.
Climate change in West Virginia is an ongoing concern. Most of the state has warmed one-half to one degree Fahrenheit (0.28–0.56 °C) in the last century, and heavy rainstorms are becoming more frequent. [ 1 ]
For USGS water-use reports, surface water is considered freshwater when it contains less than 1,000 milligrams per liter (mg/L) of dissolved solids. [2] There are three major types of surface water. Permanent (perennial) surface waters are present year round, and includes lakes, rivers and wetlands (marshes and swamps).
This was exacerbated by the surface mining activities of the 1960s and '70s, [citation needed] which brought about a severe decline in water quality due to acid mine drainage (AMD). In recent years, the limestone treatment of AMD in the Blackwater River has met with success with the effort receiving an award from the U.S. Office of Surface ...
[30] [31] In recent years, budget constraints have forced the USGS to rely on donations of time by civilian volunteers in an attempt to update its 7.5-minute topographic map series, and USGS stated outright in 2000 that the program was to be phased out in favor of The National Map [32] (not to be confused with the National Atlas of the United ...

The Tygart Valley River — also known as the Tygart River — is a principal tributary of the Monongahela River, approximately 135 miles (217 km) long, [3] in east-central West Virginia in the United States.
SWBD data covers the Earth's surface between 56° southern latitude and 60° northern latitude. It is distributed in ESRI shapefile format, divided into 12,229 files, each covering one 1°-by-1° tile of the Earth's surface. SWBD data is in the public domain and is made available online for free download by NASA.
