Water quality and processes affecting dissolved oxygen concentrations in the Blackwater River, Canaan Valley, West Virginia

Resource Abstract:
The water quality and environmental processes affecting dissolved oxygen were determined for the Blackwater River in Canaan
Valley, West Virginia. Canaan Valley is oval-shaped (14 miles by 5 miles) and is located in the Allegheny Mountains at an
average elevation of 3,200 feet above sea level. Tourism, population, and real estate development have increased in the past
two decades. Most streams in Canaan Valley are a dilute calcium magnesium bicarbonate-type water. Streamwater typicaly was
soft and low in alkalinity and dissolved solids. Maximum values for specific conductance, hardness, alkalinity, and dissolved
solids occurred during low-flow periods when streamflow was at or near baseflow. Dissolved oxygen concentrations are most
sensitive to processes affecting the rate of reaeration. The reaeration is affected by solubility (atmospheric pressure, water
temperature, humidity, and cloud cover) and processes that determine stream turbulence (stream depth, width, velocity, and
roughness). In the headwaters, photosynthetic dissolved oxygen production by benthic algae can result in supersaturated dissolved
oxygen concentrations. In beaver pools, dissolved oxygen consumption from sediment oxygen demand and carbonaceous biochemical
oxygen demand can result in dissolved oxygen deficits.
