PRESIHAJOCA JEZERA NA PIVSKEM 9 – VELIKO DRSKOVSKO JEZERO
INTERMITTENT LAKES IN THE PIVKA BASIN 9 – VELIKO DRSKOVSKO JEZERO
V pivski kotlini se nahaja 18 obicajno pojavljajocih se jezer. Proti severozahodu si sledijo Sembijsko jezero, Kalsko jezero, Laneno jezero, Backo jezero, Kljunov ribnik, Veliki dol (za Kalcem), Veliko in Malo Zagorsko jezero, Veliko in Malo Drskovsko jezero, Parsko jezero, Radohovsko jezero, Klenski dol, Palsko jezero, Petelinjsko jezero, Krajnikov dol in Jeredovce.
There are as many as 18 regular lakes in the Pivka basin. Towards the northwest the following lakes occur: Sembijsko jezero, Kalsko jezero, Laneno jezero, Backo jezero, Kljunov ribnik, Veliki dol (za Kalcem), Malo Zagorsko jezero, Veliko Zagorsko jezero, Veliko Drskovsko jezero, Malo Drskovsko jezero, Parsko jezero, Radohovsko jezero, Klenski dol, Palsko jezero, Petelinjsko jezero, Krajnikov dol and Jeredovce.
Veliko Drskovsko jezero je po velikosti tretje izmed vseh Pivskih jezer (186000 m2). Dno njegove globeli je v priblizno isti ravnini kot struga Pivke (542 m), zato je nastajanje jezera pogosto. Ceprav je voda novembra leta 2000 kar za stiri metre presegla srednji vodostaj, povrsina jezera ni bila bistveno vecja. Prostorno ovalno globel z naplavljenim dnom namrec obdaja dokaj strm skalnat rob. Na dnu Velikega Drskovskega jezera je vec kotanj, skozi katere voda pronica v podzemlje. Na severnem obrobju se jezero podaljsa v manjsi zaliv, kjer se zelo pribliza Malemu Drskovskemu jezeru.
Veliko Drskovsko jezero is the third largest lake in Upper Pivka (186000 m2). The bottom of its depression lies at about the same elevation as the Pivka river (542 m asl), so the depression is flooded frequently. Although in November 2000 the mean water level was exceeded by 4 m, the surface area of the lake did not increase significantly. The reason for this was that the oval-shaped depression with its flooded bottom is bounded along its edges by a rather steep rocky slope. The water of the lake sinks through several small ponors at its bottom. On its northern side the lake extends into a small bay, where it approaches close to Malo Drskovsko jezero.
