Ova rijeka ima dva imena, u gornjem toku se zove Matica, a dolje bliže zavodu Komanski most dobija ime Sitnica. Kada se gleda satelitski snimak jasno se može vidjeti kojim dijelom svog toka se rijeka zove jednim a kojim drugim imenom. Takođe rijeka Matica nikada ne presuši dok to nije slučaj sa rijekom Sitnicom. 

This river have two names, first part of river, with this note location, have a name of Matica, on part where are a lot of power lines start a river of Sitnica. When you look at satellite imaginery you can see how river Sitnica is smaller, like her name suggest (Sitnica = Small river). Sitnica also every summer dissapear.
