PRESIHAJOCA JEZERA NA PIVSKEM 4 – RADOHOVSKO JEZERO
INTERMITTENT LAKES IN THE PIVKA BASIN 4 – RADOHOVSKO 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.
Radohovsko jezero je edino jezero na levem bregu Pivke. Nastane v majhnem zatrepu ob vznozju Primoza in podzemno odteka v Pivko. S treh strani ga obdajajo hise in cesta, saj se Radohova vas (del naselja Pivka) siri. Podatek o srednji visini Radohovskega jezera, naveden v TTN 1:5000, je po nasem prepricanju previsok, saj je najnizja tocka oboda tega jezera na karti oznacena na nadmorski visini 536 m. Ce bi voda dejansko dosegla to visino, bi se prelivala preko ceste Pivka – Knezak proti strugi Pivke, kar pa se ne dogaja. Tudi ob izjemno visokih vodah novembra 2000 je vodna gladina dosegla komaj 535,6 m. Srednjo visino Radohovskega jezera bo torej potrebno popraviti.
The Radohovsko jezero lake is named after Radohova vas, a part of the town of Pivka, and is the only lake situated on the left bank of the Pivka river. It appears in a small pocket valley at the foothill of Primoz and flows underground into the Pivka. As Radohova vas is expanding, the lake is surrounded by buildings and a road on three sides. The value of the mean water level of the lake indicated in the BTM 1:5000, is, according to our observations, slightly overestimated, since the map shows that the lowest point of the edge of the lake lies at 536 m asl. If the water actually reached this elevation, the Pivka – Knezak road would be flooded, which, never happens. Even in November 2000, during exceptionally high waters, the water level of Radohovsko jezero hardly reached an elevation of 535.6 m asl, meaning that the average water level of Radohovsko jezero needs to be determined again.
