(OP)
can anybody give me the Cliffs Notes version of an anti-stagnation plate for use in a large wet well?

RE: stagnation
One of the pump mechanics I've worked with told me a story about that. The well was poorly designed so that when draining the brine pits, they could not be completely drained (only 14" submergence at zero pit level!) So the operators took wooden shipping pallets and tossed them in the pit to act as baffles.
I suppose it worked but pump reliability wasn't exactly a concern in those days!

RE: stagnation
Since its behind a trash rack, it looks like ... while allowing some water to flow though to the region above the pump intake, the bulk of the water is forced to enter the intake region from below the plate. The head differential across the plate would tend to maintain a surface "turnover" replenishing flow behind the plate, rather than allow water to "stagnate" against the riser. Why is that important? Well... that might keep surface water turnover going fast enough to thereby not allow large quantities of surface junk to collect near the riser before finally being sucked down into the inlet in one big pump-clogging-shutdown quantity. You know... it's like a lot of little pills taken at a well regulated pace go down easier then one big horse-choker pill.

It would prevent any vortexing from occuring above the pump inlet. The plan also shows significant other features designed to prevent vortexing or stagnation in the corners, along the bottom of the walls and below the pump intake.
