However, the project was not put into practice, since its legalization did not take place in the competent sports bodies, nor was there any record of any activity in the years 1946 and 1947. The first historical record dates from February 15, 1948. That day was played the first game of the River against Amarantino. River's first goal was scored in this game by Antônio Freire (Freirinho). The game was held in the city of Amarante-PI and the River won by 4-3. Almost a month later, on March 12, 1948, there was the so-called 'reorganization' of the club, led by Afrânio Messias Alves Nunes (River's most successful president - 11 titles). On March 15, 1948, the River had already been admitted to the Piauiense Sports Federation. In the same year, it disputed the championship of the season, of which it became champion.
