Lake Harris Lodge is a great little place. The old man that owns it has worked on my boat before and he is a stand up guy.
Coming out of that cove where Lake Harris Lodge is, you will be facing due east, with Long Island straight in front of you. This whole area is a great area during the spawn. In fact, this is where Bradley Dortch won the FLW Tour event last year (March 9 - 11 2017).
Just on the other side of that island on the SW corner there is a fish attractor bouy placed by FWC. There are many artificial brush piles in this area. Tons of opportunities for you to catch fish, even from a smaller craft.
As far as lures...you can throw a frog if you'd like - I never have luck with topwater though, due to the water clarity and the fishing pressure. You will have more luck with a soft plastic. During that time of year my go-to bait will be the speed worm (Zoom u-vibe). Either in junebug or green pumpkin. Fished on the bottom...slow...but not that slow...hopping it, letting it rest...you will definitely catch fish in said area with soft plastics.
I'm here!! Just now saw the thread.
Hope you're doing well Mike! Stay warm up there bud.
