In the winter of 2014, AUS spent 10 weeks in Great Falls, Montana, overhauling the waste gates at Ryan Dam. The crew removed the gates and gate stems, installed new gate guides, and replaced the reworked gates and stems. Utilizing Nitrox breathing mixture throughout the project, divers made 194 dives to a depth of 66′, 120 No-D dives, and 74 decompression dives.
