Abstract: In the previous period river Strumica used to flood about 7,800 ha on the river basin. Besides that the retreat of the flooded waters was very long and the flood wae doing along the whole length of the river. Length of the regulated sector of the Strumica river is 35,000 km. Discharge Q_ (5g) for the calculation was from 267.00 to 488.00 m~ (3) s~ (-1) Besides the floods before the regula- tion, as in 1963, it may be of interst to mention the flood in November 1979 after the regulation. The registrated discharge was 120.00 m~ (3) s~ (-1) and the flooded area was 119 ha. It is very important to say that these flooded waters were Less than the waters for. dimensioning of the regulated sector. This phenomenon has to be taken a speciaT consi- deration. On the basis of the known data the foIlowing measurements may be undertaken: necessary reconstructions, greater attention of the maintenance of the built objects, completion of the system and improvement of the existing hydrologicaT and meteorolo- gical observing system.
