The village was originally named Cedar Valley. Is not certain when the name was changed to Oasis. But the the name Oasis reflected the picturesque ("pretty as a picture") scene of a small farming community. In 1935 Oasis had all of 21 residents. From the big red mill there were roads going south into Arkansas. Other roads went north into other parts of Missouri. Originally Long creek had two fords nearby. Taney county built a bridge near the mill at a cost of several thousand dollars. But the bridge didn't go anywhere. One end had no access road. The other end was built up against a steep hill. There were no funds to build a road to the bridge. Nor were there funds to blast out a road from the rock on the other side. So it remained unused for 10 years,until the roads were finally built. The one-lane bridge was connected to Highway 86.
