Looks good to me!
Are you trying to give a refuge to fish fry to reduce their predation losses?
Are you trying to provide a source and concentrator of small forage species for when you predator species start feeding on that food source?
I think your hotels might possibly work for both goals. Should be interesting to observe the future results with your drone videos.
Yes to both, I'm no expert but I think the general growth rate for Bluegill in my area would allow them to be about 3 inches in a year. So if I can create habitat that will promote growth and shelter it's a win win.
Finally, you are creating lots of new surface area in your pond! Within one year, I suspect that plastic will have a solid coating of periphyton to supply the organisms that rely on that source for their sustenance.
That is my end goal, but for now I have to depend on Mother nature to supply the water.
My wife keeps telling me "It's just not our turn yet, be patient" LOL Patience is not one of my traits.
