I think your example is missing a step, overcoming inertia. A spinning space craft must constantly overcome inertia, which is especialy important with liquid.But that drop of water will have the same tangential momentum it had when it it was part of the body of water. Thus it will travel in a straight line along a vector determined by its initial inwards velocity and its tangential velocity. Since the surface of the space ship is curved inwards as is the surface of the water, this path will intersect the water again. For anyone moving along with the rotating craft, will also have a tangential speed that stays pretty much equal to that of the drop of water. So from their perspective, the water rises from the water and then falls back down. There will be a small apparent drift due to Coriolis effect, the larger the "inward" velocity of the drop, the more apparent this will be. But unless you completely remove all of the tangential motion of the drop ( effective throwing "backward" against the rotation at exactly the rotation speed), it will not fail to return to the water surface.
When a drop of water hits a water surface another drop of water is released from the spash. On Earth gravity will bring the drop down, but in the space craft lake the drop will continue upward for several minutes. The wayword drop will continue until it hits something or dissipates.
