Diversion, Irrigation Locks & Dams

We have performed several projects with the forestry service and other groups involved in the marine & forestry industry. We performed a design-build repair on the Indian Creek Dam & Fish Ladder near Gold Beach, Oregon. The footprint of the dam sets on a sliding fault where the rock hillside actually moves approximately 4” per year. We designed the dam gates in such a way that they could be shortened as necessary as the mountain moved towards the stationary fish ladder area. This would protect the integrity of the gate system and still not jam up and bust during high water-flow times. We also installed a zinc coating as a passive cathodic protection system rather than galvanizing the ladder and gate.

We have also performed several miscellaneous repairs and upgrades to boat ramps and docks.
