Typical water quality concerns with releases from hydropower reservoirs include low dissolved oxygen, inappropriate temperature for downstream uses, supersaturation of total dissolved gases, and water quality constituents associated with low dissolved oxygen. Except for supersaturation of total dissolved gases, which is usually caused by by-passing turbines and spilling water, all of these concerns are related to the limnology of the upstream reservoir. Various limnological factors affect water quality, particularly dissolved oxygen (DO) in turbine releases. This paper describes three groups of reservoirs, thermal stratification characteristics for each group, DO effects for each group, the main factors that affect DO in TVA turbine releases, and other water quality constituents that are related to low DO.
