COUNTRY STUDY FOR BIODIVERSITY OF THE REPUBLIC OF MACEDONIA<br />

A lack of m<strong>on</strong>itoring for water extracti<strong>on</strong> operati<strong>on</strong>s is also widespread. Notable<br />

examples are the Petruska, Kovanska and Sermeninska Rivers, which are dry in their<br />

lower courses during most of year due to water withdrawal for irrigati<strong>on</strong> purposes. In<br />

additi<strong>on</strong>, the inhabitants of the village of Podgortsi (Yablanitsa) dug a channel to the<br />

Podgortsi glacial lake, which is another dem<strong>on</strong>strati<strong>on</strong> of how a rare habitat type can be<br />

destroyed.<br />

A further drastic example is the proposal to withdraw water from the Boshava River<br />

in order to irrigate the Kavadarechko Pole Plain. This plan endangers the existence of<br />

this significant aquatic ecosystem (i.e., its middle and lower courses) and would cause<br />

significant changes in the hydrology of the wider area, since the waters of the Boshava<br />

River flow into another watershed (that of the Luda Mara River).<br />

The problem of water extracti<strong>on</strong> is serious enough to be ranked am<strong>on</strong>g the basic<br />

threats to biodiversity in Maced<strong>on</strong>ia.<br />

3.6.3.1. Water polluti<strong>on</strong><br />

Surface waters in the Republic of Maced<strong>on</strong>ia are seriously endangered by various<br />

sources of physical, chemical and biological polluti<strong>on</strong>. The trend toward the dramatic<br />

deteriorati<strong>on</strong> of water quality in riverine ecosystems was first noted in the mid-1970s. It<br />

resulted from the development of heavy industry and an increase in urban populati<strong>on</strong>s <strong>on</strong><br />

the <strong>on</strong>e hand, and a complete disregard for the problem of communal and industrial<br />

wastewaters, <strong>on</strong> the other. The irresp<strong>on</strong>sible discharge of high c<strong>on</strong>centrati<strong>on</strong>s of organic<br />

and inorganic pollutants over a period of years has led to the deteriorati<strong>on</strong> of riverine<br />

ecosystems (Table 23).<br />

The state of eutrophic aquatic ecosystems is also alarming in terms of polluti<strong>on</strong>. This<br />

is of particular c<strong>on</strong>cern in Doyran Lake, which is rapidly losing its identity as a lake<br />

ecosystem, instead being reduced to the status of a marsh. Although direct efforts have<br />

been undertaken for the protecti<strong>on</strong> of Ohrid Lake, little has been d<strong>on</strong>e to protect Prespa<br />

Lake, the main source of water in this relic system. In additi<strong>on</strong>, the major reservoirs<br />

Strezhevo, Tikvesh Lake and Turiya are also under great pressure.<br />
