History [edit]. Positioned on the shore of Bay Lake, near Discovery Island in Bay Lake, Florida, near Orlando, Florida, River Country featured a rustic wilderness theming, complete with rocks and man-made boulders.It was described as an old-fashioned swimming hole  with a twist of Huckleberry Finn.iver Country was much smaller than the other two water parks, yet the park remained, surviving the competition. As it did every year, River Country closed at the end of the warm-weather season (the park closed on November 2, 2001), with the expectation that the water park would reopen in the spring of 2002.
