Abstract:

The releases from Douglas Reservoir experience periods of low dissolved oxygen (DO) content during the summer months. Tests were conducted during August 1989 to determine the effects of operating experimental aeration systems overnight, while the hydropower units were not in operation. It was hoped that a storage of high DO content water could be built up in the forebay that would slowly be released during the next operation of the hydropower units. The test measurements consisted of reservoir DO profiles at specified locations, hydropower unit discharge flowrates and discharge DO content.
