Notice text
In 2013, a prototype lamprey passage structure was installed in the south fishway entrance at McNary Dam. Through biological evaluations this structure has been deemed a success and will now require a few modifications to make the structure a permanent addition to the fish ladder. Those modifications include: removing the ported hood box and making this box shorter in length to un-occlude the bulkhead guide slot and reinstalling the box, secure the knife gate in a fully open position and remove "screw jack" lifting mechanism and all supporting structure, cut and install inspection ports (4 total) in the baffle box section, and remove I-beam from channel wall outside fishway entrance. Each of these tasks will require dive work. The modification to the ported hood box will be done in the dry. This lamprey passage structure is constructed entirely of aluminum. This work will occur during the ladder outage period in the months of January and February 2019.
