The Šumera starts nearby former Dargužiai village and flows mostly southwards through agriculture lands and the Lančiūnava-Šventybrastis Forest. It meets the Obelis in Pašumerys village.

The name Šumera (or Šiumera) is of obscure origin, maybe derived from Lithuanian Germanism šiumas ('foam, decoction').[4]
