Hydropower Studies and Projects
|
|
Hydropower field studies are crucial in describing existing conditions of the river or lake, and involve a variety of data collection activities ranging from hourly water samples to seasonal aquatic and terrestrial population surveys. In essence, these studies help determine
the potential effects of a hydropower project on a river system and
evaluate the effectiveness of proposed mitigation and enhancement measures.
Thorough data acquisition and examination processes in the field, laboratory, and office contribute to fulfilling the needs of regulatory agencies and meeting the requirements for state certification under
Section 401 of the Clean Water Act. E&S scientists have conducted numerous environmental studies for hydropower projects, including:
|
|
-
Water quality reconnaissance of North Fork Reservoir and the Clackamas River, Oregon.
-
Limnological studies of Lake Billy Chinook and Lake Simtustus, Oregon.
-
Water quality and biota of the lower Deschutes River, Oregon.
-
Conditions affecting dissolved oxygen in the lower Deschutes River, Oregon.
-
Effects of hydropower development on water quality in the lower Deschutes River, Oregon.
-
Effects of hydropower development on temperature and water quality in the Sandy and Bull Run Rivers, Oregon.
-
Modeling the effect of proposed mitigation measures on the limnology of Roslyn Lake, Oregon.
-
Effects of the Sullivan hydropower development on temperature in the Willamette River near Oregon City, Oregon.
-

-
North Umpqua River water quality and paleolimnological analysis.
-
