Opal Springs Fish passage Project. Construction started in the spring of 2018, and will be completed fall 2019.
 Big projects take lots of of oversight. |  Early planning and Wahoo film crews documenting the entire project, start to finish. |  Late 2018 poring concrete into the top of the fish ladder |

 Excavating the side walls of the canyon to keep the cliff from falling onto the ladder system, down the road. |  Digging roads to move around the canyon floor |  after the top portion of the ladder was poured, the water level was brought up to test it. |

 Baffles in the fish ladder being formed before the retaining walls on the outside, very unique process to watch |  Large inflatable dams used to restrict flows from concrete construction over the ladder. |  dam sill, showing top of ladder, and operations building. |
 half the sill blocked off to keep water off the project. |  Building the lower section of the fish ladder, attraction flow shoot, all around a large boulder that could not be moved so they designed around it. |  Finished threshold |
 showing flash boards in place, that are engineered to break if the water flows to strongly for safety. |  Flash boards hold water well, and can be dropped to 4 different levels. |  Massive amounts of re-bar 1 inch in diameter are used to create concrete chute forms. |
 Concrete forms are braced as much as they can with thousands of tonnes of concrete behind them. |  this is the pool that the fish will enter the ladder in. |  Attractant flow shoot, will be adjustable to allow for multiple flow levels to attract fish to use the ladder. |
 Operation shack will allow users to change flows to the ladder and attractant flow chute. |  Excavators work daily to clear rock, clear sites, move equipment, assist in all elements. |  Cliff side shot of the final ladder being poured. |
