The old synclines of the river leave swampy areas called azmatsi. The reserve is 40 km long (stretching throughout the longose grove to the river mouth) and up to 5 km wide.

. Lake Tsonevo is also a preferred fishing spot for much of Eastern Bulgaria. The Luda Kamchiya gorge cutting across Stara Planina provides the easternmost of the three railway routes between northern and southern Bulgaria. The river valley is fertile, lined with orchards and vegetable gardens; much of it is irrigated. The lower Kamchiya is navigable for smaller motor boats.

Environment and pollution

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


Other environmental issues are that the river is purportedly becoming marshy. The water lily, torfaceous snowdrop, and white Kamchia lily are also disappearing according to the World Wildlife Fund. The Storage Battery Plant in Targovishte is a significant polluter (heavy metals) of the Kamchia River.

Cattle breeding is the second major source of water pollution and directly affects sources of drinking water. Due to a serious lack of water purification stations on cattle farms, non-purified waste waters pour into the various water basins. The same holds for the underground waters, as nitrates, phosphates, and other macroelements used in farming are dissolved and washed away by rains, to appear subsequently in water basins and mineral springs. The Kamchia reservoir, which is the primary source of drinking water for Bourgas and a secondary source for Varna, is an example. Water and sewage experts have stated that the "Komounari" hydro project should not divert waters from the highly polluted Gorna Kamchia River into the Kamchia reservoir. This reservoir, as well as other sources of drinking water for Varna, have old and low-capacity purification stations. During droughts, drinking water is drawn from the reservoir that does not meet sanitary standards.

The third main pollutant is waste water from everyday household activities in cities and small towns. One of the major problems at the Kamchia reservoir is the lack of purified water provided to the town of Kotel. The city of Varna discharges too much impure water.

However on a more positive outlook as a result of improvements to the Kamchia river, it no longer floods the dense forest. This was responsible for the appearance of Dutch elm disease
