  1. WATER RESOURCES REGIME OF THE SCUTARI LAKE BASIN WITHIN THE TERRITORY OF MONTENEGROStevan Prohaska, Ph.D.C.E Dragoslav Isailovic, Ph.D.C.E Predrag Srna, B.S.C.E Vesna Ristic, M.S.Geol

  2. SCUTERI LAKE CHARACTERISTICS • THE LARGES LAKE OF THE TECTONIC ORIGIN ON THE BALKAN • THE BIGGEST STORAGE OF FRESH WATER • AREA TO MAXIMUM WATER LEVEL – OVER 525 km2 *MONTENEGRO – about 60% of the area * ALBANIA – about 40% • WATER LEVEL FLUCTUATION • * Between about 4,50 and nearly 10,00 m.a.s.l • TOTAL VOLUME • * About 4,25 10 m3 • ACTIVE VOLUME • * About 2,5 10 m3 • AVERAGE DEPTH • * From 4,4 to 8,1O m

  3. CHARACTERISTICS OF THE CATCHMENT SCUTARI LAKE • IMPUT • THE MOST SIGNIFICANT STREAMS • *MORACA RIVER AND ITS TRIBUTARIES ZETA RIVER AND CIJEVNA RIVER - 3200 km2 • * THE SMALLER STREAMS - 2150 km2 • _________________________________________________ • TOTAL DRAINAGE AREA -5350 km2 • OUTPUT • BOJANA RIVER WHICH FLOWS TO THE ADRIATIC SEA • During the high flows the Drim River can significantly affects the Bojana River • (backwater curve can obstruct discharge out of Lake-”upstream” direction)

  4. HYDROLOGIC CHARACTERISTICS AT THE GAUGING STATIONS Average monthly and annual flow at selected gauging stations (m3/s) period 1946-1991

  5. HYDROLOGIC CHARACTERISTICS AT THE GAUGING STATIONS Average annual flows, low flows of 95 % probability and flood flows of 100 years return period with the corresponding unit-area-flow

  6. Characteristicof water level of the Scutari Lake at gauging station Plavnica (m.a.s.l.)

  7. Water balance of the Scutari Lake

  8. CONCLUSION • The Scutari Lake drainage area belongs to two states. • Area drained by the Scutari lake is characterized by relatively large • precipitation, and consequently by high unit-area-runoff. • Due to high average annual rainfall, the rivers flowing into the • Lake are water abundant, while runoff coefficient is very high. • Because of unfavorable temporal distribution of precipitation, • runoff considerably fluctuates within the year. • The extreme flows are significantly affected by the prevailing geomorphologic • and geological properties of the catchment, so that spatial variations of the • relevant parameters considerably vary in space. • Larger part of runoff (almost 65 %) come through principal tributary of the • Lake – the Moraca River, while remaining over 35 % is being contributed by small • streams running directly to the Lake from both Albanian and • Montenegro’s territory. • Primary catchment (about 80 %) contributing to the Lake belongs to Montenegro, • while 20 of it is found in Albania.
