Much of the Medieval Bulgarian Navy from the 9th to the 14th century was built at the river mouth thanks to the quality timber of the area.

The unusual coexistence of ash, oak, elm, alder and maple trees, sometimes rising up to 40–50 m with lianas climbing among the branches, creates the impression of a tropical forest, a real tangle of woods.

The Luda Kamchiya gorge, which cuts across Stara Planina provides the easternmost of the three railway routes between northern and southern Bulgaria.

A 2006 study conducted by the Institute of Oceanology and the Bulgarian Academy of Sciences on the water quality and its impact on the Black Sea coastal zone concluded that Nutrients content (nitrite, phosphate) in Kamchia River downstream does not always correspond to national water quality standards.

The comparison of data from different periods of investigation reveals a slight tendency of decreasing of phosphate and nitrites content and BOD.

A decreasing tendency was established as a positive sign of water quality evolution last years[3] Other environmental issues are that the river is purportedly becoming marshy.

[4] The Storage Battery Plant in Targovishte is a significant polluter (heavy metals) of the Kamchia River.

[4] The third main pollutant is waste water from everyday household activities in cities and small towns.

However, on a more positive note, as a result of improvements to the Kamchia river, it no longer floods the dense forest.
