Initially subordinate to the Referee of the Riverine Fleet in the Ministry of Military Affairs in Warsaw, in 1932 it was separated as a semi-independent branch of the navy based in Pińsk. In 1939 the commander of the Riverine Flotilla was Cmdr. Witold Zajączkowski and his chief of staff was Cmdr. Władysław Szczekowski. Other members of the staff were:

• Deputy commanding officer Cmdr. Henryk Eibel
• Artillery officer Cmdr. Włodzimierz Kleszczyński
• Technical officer Cmdr. Wacław Trzebiński
• Signals officer Cmdr. Bronisław Witkowski
• Intelligence officer Cmdr. Narcyz Małuszyński
• Head surgeon Cmdr. Władysław Kozłowski
• Chaplain Maj. rev. Henryk Antonowicz
• Flags officer Cmdr. Janusz Marciniewski

On September 15, 1939, the Riverine Flotilla received orders from the commanding officer of the Independent Operational Group Polesie, Gen. Franciszek Kleeberg. Because of a possible breakthrough of the German forces in the northern sector of the front, the orders for the Flotilla were to prepare a defence of a 200 kilometres long front along the Prypeć river. The forces were to be divided into 8 semi-independent task forces, each defending a separate part of the river. However, a particularly dry and sunny summer resulted in shallow waters preventing many ships from reaching their area of operations. In addition, the Soviet invasion of September 17, 1939, made the plans obsolete.
