Abstract: The diversion and outlet tunnel for Courtright Dam is in competent granite. It is unsupported and unlined. The outlet tower and trashrack are submerged. The outlet control is located in the tunnel at the axis of the dam and consists of: (1) a pipe embedded in a plug, (2) a butterfly valve in a dry chamber, (3) a cone-dispersion valve in a discharge chamber, and (4) an air-vent access shaft. Wishon Dam outlet works are similar.
