Re: Another Fish Barrier Removed
Somewhat similar to this (another read from a couple of days back) is they're building 'concrete fish ladders' below the mouth of culverts. Appears the process is pretty simple. Just measurements needed, precast and plop in place with a back hoe.
Little bit of stream bottom prep' work so the thing sets flat, that may require hand work, or if appropriate with the same back hoe.
