The Chomutovka does not have many tributaries and none is significant. The longest tributaries of the Chomutovka are:
The Chomutovka in the area of its source collects water from peat bogs and crosses many artificially constructed channels, so the main source flow cannot be determined. The length of the river is measured from the fishpond Novoveský rybnÃÂk.
The most notable settlement on the river is the city of Chomutov. The river flows through the municipal territories of Hora Svatého à  ebestiána, Blatno, Kà Âimov, Chomutov, ÃÂdlice, Nezabylice, BÃÂlence, Velemyà ¡leves and Postoloprty.
A 3-metre-high waterfall is located near Hora Svatého à  ebestiána. It is a tourist destination to which a marked path leads. About 1.5 km further down the flow there is a second waterfall with a height of 2 m.
Before it reaches Chomutov, the river flows through the mountainous landscape of the Ore Mountains. Starting with Chomutov, it flows through a flat and predominantly agricultural landscape of the Most Basin. The slope of the terrain here is approx. 0.3âÂÂ0.5%.
There are 141 bodies of water in the basin area. There are two small reservoirs in the area of the upper course, but the largest water bodies are around the middle course near Chomutov. Novoveský rybnÃÂk, a small fishpond near the Chomutovka's spring, is the only body of water built directly on the river.
There is an increased risk of flooding in the section between 23.0 and 31.8 river km, which includes the city of Chomutov and the village of ÃÂdlice.
A large area of in the spring area of the Chomutovka is protected as Pramenià ¡tàChomutovky Nature Reserve. The subject of protection are marshes and bogs, forest cover typical of these biotopes, and the occurrence of rare species of plants and animals.
Another part of the upper course (before it reaches Chomutov) flows through a valley that is protected as BezruÃÂovo údolàNature Monument. It has an area of . The subject of protection is, among other, the occurrence of butterfly species dusky large blue and scarce large blue.
