James, it would not hurt to add some additional cover near the spawning area. You said there is vegetation for the fry to hide in but it's pretty easy to add some cedars along the shoreline for additional cover. I would add them just outside the 2' depths along the spawning area. Todd Overton recommended I add 5 brush piles to help my cnbg spawn because I was short on 3" sized bg. I added 9 brush piles and after that, I had bg most everywhere to feed the lmb. I would expect the same when needing an area to protect the lmb fry. After the spawn, you can remove them if you want. I am assuming you have some cedars around the property or know of someone that will let you cut some down at their place.
