34 Danube Pollution Reduction Programme – National Review, Ukraine 4.5. Dams and Reservoirs The whole system of the reservoirs at the Ukrainian section of the river Danube is not significant. The types and major parameters of the reservoirs of the Ukrainian section of the Danube River basin are presented in Table 4.4. and Table 4.5. Table 4.4. Type of reservoirs Large reservoirs, more than 10 ml. m 3 Reservoirs of the Ukrainian Section of the Danube River Basin Number of reservoirs total water volume under normal conditions area of water table 6, including 4 of 1236,0 282 km 2 ml. m 3 capacity more than 100 Reservoirs, less than 33 1308,0 530,6 km 2 1 ml. m 3 Ponds 602 56,5 38,3 km 2 Table 4.5.

In Odessa region area of lands under dams (or bank protection) is 1500 ha. The reservoirs at the river Tisza do not influence the river flood. There are a few reservoirs in the Prut River basin with additional volume for flood regulation, but their influence on floods is low. The effect of reservoirs on floods is evident for flood of 5 % and more and their permanent discharges 700 m 3 per sec. The floods of lower hydraulic loads are regulated in much less degree. The regulatory capacity of Danube lakes-reservoirs is limited and practically does not influence flood events. Existing constructions, canals and waterlocks are outdated and are not efficient even for minimal requirements. Even small floods may destroy them and large areas may be flooded. Locations of reservoirs and ponds as well as major flood protective construction are presented on Maps 2.1., 2.1., 2.3., 2.4., also see 4.2., 4.3.
<strong>Technical</strong> <strong>Reports</strong> – Part C: Water Quality 35 4.6. Other Major Structures and Encroachments Hydraulic constructions are mainly presented by irrigation systems in Odessa and antiflood constructions in Zakarpattia region. In Ivano-Frankivsk and Chenivtsy Region these constructions are less important. (Table 4.6.; 4.7.). Table 4.6.

Additionally, there is a sector water intake in the village Salmany. Major irrigation systems of Odessa Region along the Danube River are: Prydunaiska Irrigation system; Bolhrad Irrigation system; Suvorovo Irrigation System and Tatarbunary Irrigation System. 300,6 km of dams are constructed along Danube riverbank. The dam through canal Danube Sasyk is 14 km long. In Zakarpattia Region the irrigation systems and irrigation canals are not available. In Ivano-Frankivsk Region area of irrigation canals is 294 ha and has 1970 m of water routes. The major flood protection constructions are presented in Table and at the Maps. The regulation of flood with system of reservoirs was not accepted for Transcarpathian Regions because of high costs of construction and long expenditure return period (between 25 and 100 years) (Table 4.8.).
