Solar panel and control box for the new automated fish-counter. This was not here at the beginning of my fish counts for NSRWA. Seems as if this was added just prior to April 29, 2015.

pembroke-alewife-13 I was told this is an Alaska steepPass fishway. It's generally pre-fabricated and simply dropped into place assuming the appropriate mountpoints are present.

Apparently one of the problems with this ladder is contrlling the waterflow to the right level. At one point, the water was flowwing too fast and that was causing the herring to bounce out of the ladder. You can see a few of them in the bottom of the pool. One of the herring commisioners told me that the water flow has to be just right.
