The height of the link-in point is problematic, too; if you drop ten feet onto an inflatable raft, you’ll likely overturn or even break it, and raising a platform ten feet above waterline seems like a considerable engineering challenge. You might end up keeping open water under link-in and having a ladder to climb up into the boat nearby.
Once you have a base of operations, you can start making proper studies: sounding the depth of the lake, chemical analysis of the water, marine biology, and so forth.
