Hi, sorry for my mistake i recently started mapping and i made afew mistakes, the reason i chose the name plavūpe is because it is reffered to as this by the locals,  plavūpe does not end there but isntead continues underground and continues and goes above ground after passing through the railway and continues through the lake, gathers waters from the 4 pedas lake and continues on word receiving waters from a small un named tributery and then flows into a small ditch witch connects to the dougava river, the small stream is one lf the few natural streams in the area, i scouted out the entire length of plavūpe today about  a hour ago,  you can also see the stream on old soviet maps . Im a local and live by the ditch so that's the reason it peaks my interest
