    "grand-mac-daddy of fish ladders" really got me

    Very informative. Thanks. I want to convert this diversion ditch into pools and connect then via a ditch ladder simulating what I find in the wild to create a refuge for the native wild brook trout above the agricultural runoff……. I was shocked to become aware…. Can someone please tell me the maximum height a brookie can jump between pools? I can over summer them through drought with deep trench swales from hillside springs in the fields

      I found a paper online that experimented with this. According to them, wild brookies cannot jump very far, well under a foot. There's a sweet spot for fish size, too, with larger ones that could theoretically jump higher being less likely to colonize new habitat and smaller ones that like to push up into newly opened reaches being less good at jumping. I wouldn't count on brook trout getting past a hop of more than 3" to 6".

    Don’t talk, show the actual ladder

      Thanks for your suggestion for improving the video. Views of the fish ladder as a whole appear at the 51 second mark. The idea there was to show the whole thing and convey that it's a pretty big, elaborate structure. Various views of the fish ladder and its components feature between the 4 minute and 14 minute marks while Jim explains. One goal of these videos is to give a glimpse into the science behind things we see every day, like fish ladders. If you're interested in more views of fish ladders, do an image search and let the audio from our video play in the background while you browse the numerous fish ladder pictures available there.
